Now, I'll turn the call over to Dheeraj. Dheeraj?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Thank you, Tonya. Hi, everyone. Thank you for joining. Q1 marked another strong quarter for Nutanix, with billings, revenue, gross margin, and EPS performance better than our guidance and consensus. Before getting into our Q1 results, I'd like to start the call by discussing the business transformation within Nutanix. You might have heard from us that we are increasingly taking a software-centric approach to go to market and financial reporting. I want to take the opportunity to zoom out and talk about the why behind our packing and distribution strategy over the last six years, and the somewhat obvious why of the future software strategy.
I borrow from my annual shareholder letter to set the context. Digitization, or virtualization, as we call it, has been an unstoppable phenomenon in computing. We saw this with music, photography, shopping carts, and maps, as they all converged into pure software and as digital constructs in our consumer lives. We brought the foresight to enterprise storage and compute. And by doing so, we improved machine productivity by bringing data closer to applications, and also human productivity by breaking down artificial walls in IT departments. By standardizing on commodity hardware and a common operating system, we delivered economies of scale that were unprecedented in enterprise datacenters. But none of this would have been possible if we hadn't obsessively focused on product design. The elegance of Nutanix products is in their simplicity and in our ability to bring a consumer-grade experience to enterprise-grade systems.
We are now on a path to digitizing networking, security, and effectively, the entire datacenter. This architecture, of an undifferentiated hardware running software services that then bring all the differentiation, is the only way to operate a cloud if the enterprise if the enterprise wants to stay in the business of computing. In 2011-'12, software-defined anything was too abstract for our customers to put their arms around. So, vendors were conflicted because they sold billions of dollars worth of hardware equipment that we, as disruptors, were digitizing into pure software. Our only route to market was to take control of our own destiny. The Nutanix appliance was born. We now had an iPhone-like design patent that people could touch and feel, and the channel could sell. Customers loved us for bringing the web-scale culture to them in a white box with the robust software, aided by a word-class customer service, was meaningfully more delightful than the current experience of sticking together vendors and inside teams that constantly finger-pointed at each other.
Over time, as our architecture gained popularity, we relaxed our opinion of our own hardware and signed OEM relationships. We built the muscle memory on a two-hop customer service. Also in the last 18 months, we signed large ELAs in pure software, come up with your hyperscale customers running OCP-like software equipment. In the last 12 months, we ported our software to every major x86 solo vendor. IBM-powered microprocessor, ruggedized warfare servers, and even 4x4-inch Intel miniservers for the IoT edge. We now have a meaningful competitive advantage in being the most portable operating system built for the enterprise cloud. We have kept growing our total addressable market as we portered our software to all these platforms in the last three years.
A software-only form factor gives us ubiquity. It also enables friction-free access of our technology to tinkerers, prospects who are at the top of the sales funnel. But the change is beyond just the product. It includes thoughtful changes to the port to cash process, sales compensation, software downloads, license management, and new tools at the top of the sales funnel. These changes also prepare us well as we embrace the subscription model next year with our Xi, spelled X-I, Cloud Services. The company that is obsessed with an iPhone-like motif is ready to institutionalize a pure software version of its operating system. And all that without compromising customer experience and without being negligent about the boundary at which hardware and software meet.
Shifting gears to product, over the past two years, we've built a multi-product portfolio. We have built our own hypervisor AHV, which has consistently grown in market share quarter over quarter. We introduced AFS, a software-only scale-out filer to remove yet another hardware silo from enterprise datacenters. We added Prism Pro and Calm for operations management and model-driven automation, respectively. At a recent .NEXT Europe customer conference in Nice, France, we continued this innovation with the announcement of the Acropolis Object Storage Service, Acropolis Compute Cloud, and Nutanix App Marketplace. These services, which will be included with our software, help our customers run a growing set of cloud native applications.
Acropolis Object Storage Service supports the growing number of applications with large unstructured data, and enables application development teams to consume storage as a high performance, on demand service, similar to public cloud offerings. Complementing Object Storage Service is our new AHV-based compute service, the Acropolis Compute Cloud. This new capability will help enable the enterprise customers to economically scale compute resources to better support applications like distributed analytics workloads, large-scale frontend web services, Citrix XenApp deployments, and other CPU-intensive workloads.
Finally, on Nutanix Calm, spelled as C-A-L-M, we announced the addition of the app marketplace. This new marketplace service empowers IT teams to rapidly deploy fully validated applications via self-service portals, so new workloads can be deployed quickly and easily.
Xi continues to be on track for a mid-2018 release. We are making meaningful process with Google on the go to market and deployment strategies around the world. On a related note, the bare metal as a service offering from the public cloud providers is a very promising breakthrough for our cloud OS, as we explore even more ubiquity for our software. Through APIs, automation, and digital delivery, bare metal in the cloud even further commoditizes the commodity server.
Alliance partnerships move from business relationships to developer relationships, aided by SDKs and APIs. The next few years will be exciting in our cloud OS journey, as we forge deeper alliances with new hardware partners in the cloud.
At .NEXT, one of our most intriguing announcements was a remote IoT Edge. We laid the foundation of the IoT edge with our 4x4 miniserver form factor port and Prism Pro software. Beyond providing an invisible IoT infrastructure, we are building an event-based method bus application that manages data between the Edge and the cloud core. Both object storage and this IoT data service are early forays into building platform services for developers beyond traditional infrastructure for IT operators. Consumer cloud operators like Amazon and Facebook have leveraged a lot of open source to their competitive advantage. Similarly, in the last eight years, they embraced Linux to build an elegantly simple yet enterprise-grade hypervisor and network virtualization, and also NoSQL databases to build the core metadata services of our operating system.
2018-'19 will be years when we embrace open-source Apache Software Foundation services even further to deliver consume- grade developer building blocks in Xi. Linking these building blocks into hybrid services is our big bet around the future of cloud. The true north for us is to provide a common IT experience in a hybrid cloud world, and we try to blur the line between owning and renting computing.
Shifting to some Q1 KPIs now, last quarter, I shared the progress we have made in signing large deals. We continued our large deal momentum with 478 customers that have purchased in excess of $1 million lifetime to date, up 74 in the first quarter, and they have collectively spent nearly $1.4 billion with us in lifetime bookings. Additionally, we have 206 customers that have purchased over $2 million, up 40 from last quarter; 47 customers that have purchased over $5 million; and 16 customers that have purchased $10 million with us lifetime to date.
As we have shared in the past, customers are increasingly trusting us with their most machine critical workloads. Our top three deals in Q1 were all in the federal vertical, and together comprise more than $15 million in billings. In two of those engagements, the customer went all in with AHV, our hypervisor, choosing to standardize on our built-in hypervisor or other virtualization offerings. The first customer, which is the largest revenue generating civilian agency in the federal government, selected Nutanix because of the inherent security and rapid time-to-value our platform provides. This customer will take advantage of our Prism Pro software edition, benefiting from reduced complexity and costs for operations and management. The other customer, a unit within the United States Armed Forces, which handles day-to-day operations around the globe, will use the Nutanix platform to support facilities that provide recreational and educational opportunities to the children and youth soldiers and U.S. Armed Forces civilians stationed at bases in both the U.S. and abroad.
This quarter also saw great momentum in the healthcare vertical, with seven deals greater than $1 million. One such deal was with Baylor Scott & White Health, another existing customer that is using our platform to host Epic, its electronic health record system, and power its DNA sequencing environment. In fact, using the Nutanix solution, Baylor Scott & White Health has been able to process DNA sequencing results five times faster and at greater volume than its previous solution.
Another great used case in the health services space is with an S&P 500 company that operates one of the largest clinical laboratory networks in the world. The company is replacing its legacy of three-tier infrastructure with Nutanix, using our platform to run a host of different workloads, including powering the lab tests for a popular privately held personal genomics and biotechnology company.
Outside of the healthcare and federal verticals, a leading entertainment provider with 17 facilities, including casinos, hotels, and show theaters, uses our platform to support its value gaining management software. To give some context on that workload, when the gaming management system goes down, the casino stops running and customers leave. It's the company's moneymaker, and they trust this mission-critical application to Nutanix.
Another customer, an international group active in the design, manufacturing, and sale of watches, jewelry, and watch components, which had previously committed to a VMware-centric strategy, selected our platform because of its easy to use and simplified management console.
In this quarter, we continue to see customers refocusing their infrastructure strategies away from public cloud-only ambitions. One such customer, a leading provider of device insurance, warranty, and support services for cellphones, consumer electronics, and home appliances, began adding a variety of machine-critical workloads to our platform after a yearlong focus on evaluating and testing AWS. Cost, service-level agreements, and security concerns were among the contributing factors for the shift.
We saw robust demand for our software upsells, including Prism Pro and our ultimate software license. In Q1, Prism Pro adoption increased by 40% quarter-over-quarter. We also had 16 Prism Pro deals in excess of $100,000, including the previously mentioned largest revenue generating civilian agency in the federal government, which is one of our largest deals this quarter.
Another customer a Fortune 100 multinational company that produces a variety of commercial engineering, aerospace, and consumer products continues to standardize the Nutanix software, including adding Prism Pro to their 300-plus Nutanix nodes so that they can execute proactive capacity planning to lower operation costs and reduce risk. This customer continues to invest in and rely on the Nutanix enterprise cloud platform across their enterprise, inclusive of mission-critical applications such as ERP and PLM.
One win of particular interest is with the Department of Defense Agency. This software-only deal, coupled with our software with hardware from a partner, Klas Telecom, K-L-A-S Telecom, in order to deliver a ruggedized hyper convert solution that is roughly the same size as airline carry-on luggage. This agency plans to deploy these ruggedized Nutanix appliances across its field teams, who will operate the units on battery power to maintain communications and other critical applications in war zones.
In closing, I'm very pleased with how the company is evolving toward its next act. Lou Attanasio, our new Chief Revenue Officer, will play a pivotal role in our transformation to software as he leads our growing sales force and a journey that blurs the lines between owning and renting computing. This now allows Sudhish Nair, our President, to focus on strategic partnerships -- importantly, Xi and its developer-oriented services, and our largest of the large customers. I sincerely believe that we now have a dream team to do justice to our mission.
With that, I'll turn the call over to Duston to discuss our strong Q1 financial performance. Duston?
Duston Williams -- Chief Financial Officer
Thank you, Dheeraj. I'm pleased that our Q1 results came in a bit better than expected, primarily driven by a solid quarter in our federal vertical. And as a reminder, we adopted ASC 606 beginning this quarter, and our results are reported under this new method of revenue recognition.
Revenue for the quarter was $276 million, growing 46% from a year ago and up 9% from the previous quarter. We built $315 million in the quarter, representing a 32% increase from a year ago and a 9% increase from Q4. Our performance in our geographic regions were essentially in line with what we would expect for the first quarter of our fiscal year. As expected, our OEM business, although with approximately 10% of bookings, waned a bit from the very high level we experienced in Q4. On the upside, we saw good performance in our federal business, as well as continued strength in the APAC region. This strength was somewhat offset by seasonal declines in our North American commercial and EMEA businesses.
Once again, we were pleased to see the number of large deals in Q1 keep pace with the strong levels we experienced in Q4. We booked 15 greater than $2 million deals in the quarter, and that was consistent with our strong Q4 performance. Bookings from our international regions were 37% in Q1 '18, up from 34% in Q1 '17. Our gross margin for the quarter was 61.9%, which was higher than our guidance and compares to 65.4% in the year ago quarter and 62.6% in the prior quarter. The Q1 '18 gross margins benefited by approximately 1.5 percentage points as we purposely eliminated more than 9% of revenue attributable to our pass-through hardware revenue. Our operating expenses were $193 million, below our guidance by $7 million, primarily due to timing of new hires and other personnel-related expenses. Our non-GAAP net loss was $25 million, or a loss of $0.16 per basic share.
Before I review the balance sheet highlights and our Q2 guidance, this is a good time to take a step back for a high-level discussion on how we see our business model evolving over the next several years. Today, we are software company -- more specifically, an enterprise cloud operating systems company, that up until now has delivered a majority of its software via its own branded appliance and recognized the associated hardware revenue. This approach made sense at the beginning, as it allowed us to stand tall among our competitors in an emerging market, while at same time allowing us to build out a direct sales force and brand for what was early on an unknown company. It was this very same approach that yielded 60% gross margins, despite our significant software content, and which inadvertently disguised the true nature of the company. This left many investors wondering if we were really a software company or just another storage or appliance company. And despite our best efforts to establish Nutanix as a software company, in the minds of many investors, you simply are what your margins say you are.
Going forward over time, Nutanix will emerge as exactly what it is, an enterprise cloud operating systems company. In conjunction with this, investors should expect the following to occur over the next few years. First, we will begin the migration away from pass-through hardware-related revenue. Beginning last quarter, we started the gradual migration away from recognizing pass-through revenue attributed to the hardware portion of our business. Today, the hardware portion of our business is approximately 26% of our total billings. This transition will come in two parts -- first, with straightforward changes that will allow us to step aside for most hardware-only invoicing by enabling our legacy appliance manufactures to begin selling the NX hardware directly to our distributors; and secondly, by simply focusing on more software-only transactions, allowing our customers to then choose to run on a large number of server platforms.
It is important to know that stepping aside from this pass-through hardware does not in any way infer that customers are not ordering NX appliances. To be very clear, our customers' choices and experiences will remain the same. We expect this transition to take a year or so, and result in the elimination of at least 80% of all pass-through hardware-related revenue. All things being equal, the direct impact of this specific change would result in significantly higher software content and significantly higher gross margins, with no change to our growth and gross profit dollars. Probably the most important point to make here is that this change will have absolutely no impact to our future growth rates of our software and support billings, that being the portion of our business today that represents 74% of our billings. Over time, we would also hope to gain additional selling leverage that naturally comes from focusing on software-only transactions.
The next modification in our business you should expect will be a gradual shift to ratable Software-as-a-Service revenue. Once our Xi Cloud Service offering takes hold, starting with services such as disaster recovery, we expect to see the emergence of some ratably recognized Software-as-a-Service revenue.
And lastly, over time, we will start to position the Company for increasing ratable Software-as-a-Subscription revenue. Although not immediate and not yet quantifiable, with the introduction of both our Xi Cloud Services and Nutanix Calm, we believe we have the option to convert some of our perpetual and term-based software streams into ratably recognized subscription software. To help incentivize and expedite this transformation, starting February 1, 2018, our fiscal Q3 '18, we will start the process of compensating our sales teams on software-only related bookings. Once the change is fully implemented, sales representatives will no longer be compensated for pass-through hardware sales.
To summarize, this transformation of our business will take place methodically over an extended period of time. The first phase will result more perpetual and term-based software as we begin to significantly reduce our pass-through hardware revenue. We then expect to see the emergence of ratable services revenue, followed by a gradual shift to more ratable subscription revenue over time. As we start to shift away from pass-through hardware revenue, we will also take this opportunity to change how we report the software content of our business. The previous methodology had us reporting software as a percentage of total bookings, with the software content comprised of OEM licenses, upsell of our addition software, and other miscellaneous software sales. What this methodology excluded was the significant software content attributable to the base operating system that was bundled into the appliance sale.
Going forward, we will add the software content attributable to our base operating system into the total software metrics. The base operating system is simply calculated by taking the total billings attributable to the appliance sale, less the billings of the actual cost of the hardware. As we increasingly separate ourselves from the hardware sales, the related revenue and cost of goods sold would be eliminated in equal amounts, this amount representing the actual cost of the hardware. Under this new software-centric reporting, based on billings for Q1 2018, the splits of the business would be as follows: software and support, 74% of total billings, and hardware, 26%. It is this 26% attributable to the pass-through hardware that will mostly be eliminated overtime. We would encourage you to review the Q1 Nutanix Investor Deck located in the Investor Relations section of the corporate website for further details surrounding this new software-centric reporting and the associated historical breakouts.
So, in summary, what would Nutanix have looked like over the last 12 months, if we chose not to build any pass-through hardware-related transactions? The resulting business would have been very interesting, basically yielding an $800 million pure software and support infrastructure company with gross margins above 80%, while at the same time being a market leader within $100 billion TAM. That's what Nutanix would have looked like over the past 12 months, void of any pass-through hardware billings. This level of size, growth, and gross margins compares very favorably to other software and service companies such as Splunk, Lassian, Tableau, and others.
Now, let's turn to the balance sheet for a few highlights. We closed the quarter with cash and cash equivalents of $366 million, up from $349 million in Q4 DSOs on a straight average with 57 days. That was eight days lower than the 65 days reported in the prior quarter. The weighted average DSO was 27 days in Q1. We generated $10 million of cash from operations in Q1, which was negatively impacted by $8 million of ESPP funding. We used $8 million in free cash flow during the quarter, and this was also negatively impacted by the $8 million of ESPP funding.
Now, onto the guidance for the second quarter. The guidance on a non-GAAP basis is as follows. Revenue to be between $280 million and $285 million, gross margins between 62.5% and 63.5%. This revenue and gross margin guidance is expected to yield approximately $178 million gross profit dollars, versus the current Q2 gross profit consensus of about 173 million. Operating expenses of approximately $210 million and a per share loss of $0.20 to $0.22 using the weighted average shares outstanding of approximately 161 million shares.
This guidance assumes that we will eliminate approximately $12 million or 15% of our pass through hardware revenue and an equal amount of hardware cost of sales during the quarter. Without this change, we would have guided revenue to the range of $292 million to $297 million, with gross margins of 60% to 61%. And lastly, for modeling purposes, we anticipate eliminating up to two-thirds of all pass-through hardware revenue by the end of Q4 '18. Additionally, we have also assumed that for every $5 million to $6 million reduction in pass-through hardware revenue, gross margins should increase by about 80 to 100 basis points.
At this point, Operator, if you could open the call up for questions, that would be great. Thanks.
Questions and Answers:
Operator
Thank you. At this time, I would like to remind everyone, in order to ask a question, please press * and the number 1 on your telephone keypad. We'll pause for just a moment to compile the Q&A roster. Your first question comes from the line of Jason Noland from Baird. Your line is open.
Jayson Noland -- Robert W. Baird -- Analyst
Oh, OK. Great. Congrats on the quarter, and exciting stuff on the transition in the business. I guess, Duston, I wanted to ask on the elimination of 80% of your pass-through hardware in about a year, what has to happen over the next 12 months? I assume there's lots of negotiation with distributors to take that hardware revenue?
Duston Williams -- Chief Financial Officer
Yeah, that has already happened in the U.S., so that's the good news. The team has done an excellent job getting those -- getting that process in place. So, North America is done. We need to now go execute on it, but those agreements are now complete. And we're now off working on some international regions.
Jayson Noland -- Robert W. Baird -- Analyst
Okay. And we've spent some time on our team trying to figure out what your long-term operating model would look like. And I don't know if you are ready to point us -- point in any directions here. But would the profitability be pushed out a bit with more leverage in the model longer-term?
Duston Williams -- Chief Financial Officer
Yeah, we'll give a full -- I think at the beginning of the year, we'll have a full deep dive on the operating model and how that changes. Obviously, gross margins go up substantially. The operating margin goes up and some other things there. And I don't think, from a cash flow perspective, there shouldn't be any major changes there. We've been hovering plus or minus, and that's kind of how we've been running the business from that perspective. But yeah, we've been doing awful lot of work on the long-term model and things like that. So, at some time, I think probably at the first quarter of the calendar year, we're anticipating scheduling some type of probably analyst event that will give a pretty deep dive into all that.
Jayson Noland -- Robert W. Baird -- Analyst
Okay. Lots of questions, but I'll cede the floor. Thanks.
Operator
Our next question comes from the line of Matt Hedberg from RBC Capital Markets. Your line is open.
Matthew Hedberg -- RBC Capital Markets -- Analyst
Hey, thanks, guys. I'll offer my congrats again. I'm curious now. This is the second quarter in a row you guys have had really strong large deal momentum. I know you highlighted the federal vertical in particular this quarter. Can you talk about sort of the momentum that you're seeing there? How do you see that large deal funnel progressing here in a software-only model? I'm sort of kind of curious about the pipeline of these larger deals.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Thanks, Matt. This is Dheeraj. Definitely, we've seen an uptick in the last three quarters. That's also because of the way we segmented our sales force. The focus is on global accounts and enterprise accounts -- strategic accounts, I should say. And a lot of the replatforming is now happening. So, for the first three, four, five years of selling, we were going and selling workloads and project-based spend, trying to go and exhaust the project-based spend. But many of our existing customers, we talked about 474 of those million-dollar customers. They are massively strong return customers for us, and we really focus hard on them. And you can see that from our net promoter score as well, which is one of the big determinants of large deals and the large deal pipeline for the last three quarters and the coming quarters as well.
Matthew Hedberg -- RBC Capital Markets -- Analyst
And then, I was curious .I don't think you guys mentioned in your prepared remarks anything about the GCP relationship. I know it's probably still early, but is there any updates on the progress of that?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, I talked briefly about this in my call script as well. Making good progress, I think. You know, we are talking -- engaged with Google on the locations, like where do Nutanix's products go. And we've identified a couple of regions, both here in the U.S. and outside the U.S. as well, to make Nutanix as a service where customers can rent as well as own us. So, sometime in the middle of next year you'll actually see a big update around Xi, which is the cloud service. And it's not completely dependent on Google, but that's a big part of our overall push, is to go together as partners.
Matthew Hedberg -- RBC Capital Markets -- Analyst
Great. Thanks a lot, guys.
Operator
Your next question comes from the line of Andrew Nowinski from Piper Jaffray. Your line is open.
Andrew Nowinski -- Piper Jaffray -- Analyst
All right, thank you very much, and congrats on a great quarter. In the transition to your software model, are you assuming that most customers can do the integration work themselves between hardware and software, or are you going to become more reliant on channel partners like CW to do the integration work for you?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, it's like a pyramid, Andrew. If you think about the top of the pyramid, it will be driven by global SIs. And especially as we've sold the software, some of which could actually go direct as well. So, we'd expect the channel and the SI to come back and help utilize that, deploy them on servers, on commodity servers, x86 servers. In the middle of the pyramid, we expect more of the resellers to do that. We made it extremely simple to actually go and deploy Nutanix. That's one of the biggest values of being an appliance company, the roots, because we really understood the value of the hardware/software boundary itself. So, we've made a lot of those deployments one-click. And the base of the pyramid could still be going through as NX. And, as Dustin mentioned, it could be an NX that's basically going through the ST model, where we just take the order, but then the software comes to us and the hardware goes to the hardware vendor.
Andrew Nowinski -- Piper Jaffray -- Analyst
Okay, got it.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
And I just want to say one more thing about customer success, that we just seeded a team around customer success, where our technology relationship managers, we call them TRMs, who will be very active at the top of the pyramid with our largest customers. And we expect to get professional services, our own professional services, as well as the EPS of our resellers and the SI partners themselves for the middle of the pyramid.
Andrew Nowinski -- Piper Jaffray -- Analyst
Great, that makes sense. And then I just have a follow-up. You had a fairly big jump in percentage of nodes sold with AHV this quarter, up to 28%. Are you seeing customers just getting more comfortable with Acropolis, or have there been changes on the competitive front that are prompting more customers to look at new options such as AHV? Thanks.
Duston Williams -- Chief Financial Officer
Yeah, it's Duston. Yes, just on that metric there. We did continue to do great, as you can see from the investor presentation there. The only thing we did make a little tweak there, as you can see in that chart there, is that we've now, I think, more appropriately shown this just as NX nodes, and not including the OEM business in there, as you might expect. It's heavily tilted away from AHV. So, that tweaked it a little bit, but not substantially.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
And I think one of the correlations is with respect to our partnership with Citrix. The VDI business went up a little this quarter, and we've been doing some really good with Citrix using the AHV hypervisor and the Citrix workload.
Duston Williams -- Chief Financial Officer
Yeah, and if we had used the exact same metric last quarter, I think it would have gone from 24 to 25. So, not a substantial change there, but up no matter what.
Andrew Nowinski -- Piper Jaffray -- Analyst
Great. Keep up the good work.
Operator
Your next question comes from the line of Aaron Rakers from Wells Fargo. Your line is open.
Aaron Rakers -- Wells Fargo -- Analyst
Yeah, thanks for taking the questions as well, and congratulations. Just looking at your slide deck and looking at slide number seven -- and I can appreciate the fact that you're looking at the mix of business based on billings. But just simple math, I guess, looking at an 80%-plus gross margin on your software support revenue would leave us to think about a progression of gross margin into at least the 70, if not mid 70% range. So, I guess the first question is, is that how we should be thinking about the overall progression of the gross margin? And then to follow up on that, I think last quarter, you talked about adding $10 million of OPEX per quarter. It looks like your guidance is a little bit less than that. So, I'm curious of how we should think about the OPEX trajectory through the course of this year relative to your prior commentary?
Duston Williams -- Chief Financial Officer
Sure. Yeah, on the first one -- and I actually gave you the metric because I wanted you guys to get this correct. You can do your own assumptions there. We gave you a couple data points -- two-thirds elimination by the end of the year at the end of Q4. And then for every $5 million to $6 million that you're gonna take out of your models of hardware, pass-through hardware revenue, gross margins should go up 80 to 100 basis points. So, it's a pretty simple way for you to go get to that endpoint, and it's from -- it's your models, obviously. But you should be able to easily do that from that perspective.
On the expenses, yeah, I mean, we came in a little -- we were a little under hiring. It wasn't intentional. We didn't try to drive it down. We've still got, obviously, a lot of priorities and things like that. So, we'll continue to -- you'll see expenses -- I don't think we'll continue to be massively under. There's a lot of things going on, lot of hiring and things like that, so.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, especially as we focus on the unrecovered global accounts and the unrecovered enterprise accounts, because we've done one phase of segmentation, but now we need to go back and figure out if we need to resegment it in the coming quarters as well.
Aaron Rakers -- Wells Fargo -- Analyst
Okay. And then a quick follow-up. If you could, I would be interested in comment -- your comments on the IBM relationship, and then I'll cede the floor.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yes. So we did a GAR product a couple of months ago with IBM, and we have some really good momentum on the Linux applications. We have some proof of concepts going on in very large customers, both in the U.S. and Canada, and beyond as well. And we are working on the AIX product, which is one of the biggest sort of product sort of coverages that IBM has. And virtualizing that itself would grow the time on this whole relationship. So, we expect to see some news in the coming quarter or two. The product is off to a good start with the proof of concepts going on right now.
Aaron Rakers -- Wells Fargo -- Analyst
Thank you very much.

Your next question comes from the line of Jason Ader from William Blair. Your line is open.
Jason Ader -- William Blair -- Analyst
Yeah, thank you. Hey, guys. I have a question on the -- let's see what slide it was. Oh, it's number seven. You assume support and other margin of 55% for future periods. And when I look at the model, it looks like the support gross margins are quite a bit higher than that. So, wondering what is happening with 55%?
Duston Williams -- Chief Financial Officer
Yeah, good question. Nothing happening there. This includes support. It includes the small piece of professional services that we have, and then some residual other COGS that we have on a quarterly basis. So, nothing massively trending there. It's just kind of an all-in residual of what would be remaining there. And again, professional services is included in that support piece.
Jason Ader -- William Blair -- Analyst
Okay. So, that doesn't include the residual pass-through hardware. That's still . . .
Duston Williams -- Chief Financial Officer
Correct.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Correct.
Jason Ader -- William Blair -- Analyst
Right. Okay, so right now, your support gross margin is in the low 60s. So, what --
Duston Williams -- Chief Financial Officer
Yes, it's hovered 60, 62, or something like that. There's just some other COGS that we capture in that total, but it really is truly residuals left there. There's just some other stuff that gets bundled into there.
Jason Ader -- William Blair -- Analyst
Okay. So, today, that's in the product side.
Duston Williams -- Chief Financial Officer
Yeah, you could argue either way. But it's residual, so it has to go someplace.
Jason Ader -- William Blair -- Analyst
Okay. I gotcha. All right. And then, Dheeraj, I see the guidance. If you include the pass-through hardware, obviously very strong. So, I'm assuming that with the strong federal performance, is it fair to say that you had some good backlog on the enterprise side and the commercial side?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, I'll let Duston answer this one.
Duston Williams -- Chief Financial Officer
Yeah. Yeah, the backlog didn't really surprise us for Q1 from that perspective. So, it bounces up and down, and we've maintained a reasonably healthy backlog over the last several quarters. So, we'll see how it progresses here with Q2, and obviously, we have the end of the calendar year. So, we will see how things play out with those efforts.
Jason Ader -- William Blair -- Analyst
Okay, and then last one quick one from me is on the billings differential from revenue. Is that just because you had a very strong billings quarter a year ago? And how should we think about the differential going forward between billings growth and revenue growth?
Duston Williams -- Chief Financial Officer
Yeah, I don't think you'll see that much difference going forward. About a year ago or so, we had a little tweak to support pricing and how the mix to bill and revenue kind of tweaked a little bit there. But I think you're seeing some residual of that. But I wouldn't expect that you'll see that level of delta going forward on a year-over-year basis.
Jason Ader -- William Blair -- Analyst
Okay. Thanks, guys. Good luck.

Your next question comes from the line of Simon Leopold from Raymond James. Your line is open.
Simon Leopold -- Raymond James -- Analyst
Great. Thanks for taking my question. Just first wanted to see if we could clarify the federal. You highlighted it was strong this quarter. If we could just get some quantification around contribution, percent of revenue from federal, and where it is typically, and how much of this is seasonal?
Duston Williams -- Chief Financial Officer
Yeah. So, we expected federal to be reasonably healthy, and it was pretty good. If you look at our federal business in total, on average, it averages 10% to 12% of bookings or so. And then Q1, it pops up. So, we had a pretty good popup in Q1. It wasn't quite exactly to the same percentage as last year. But the team did a great job. We had lots of large deals, as Dheeraj mentioned there. So, a little bit better, but not massively better.
Simon Leopold -- Raymond James -- Analyst
Great, and then -- sorry, go ahead.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
I was gonna say that obviously, the CR, the continued resolution, for most of the year, a lot of that budget will flush at the end of their fiscal, which was September.
Simon Leopold -- Raymond James -- Analyst
Great. And I wanted to see -- you gave us, I think, a number of helpful insights in terms of the software pivot, of how it affects our modeling and how the analyst might look at the financial metrics. But I guess what I'm a little bit hazy on is your customer experience -- how your customers will view Nutanix, how they're going to interact with you. I think my worry is, are they becoming more at arms length in terms of their interaction with Nutanix? Could you help us get a better understanding of, really, the interaction level and how that either does or does not change? Thank you.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
That's a great question, and we think about it all the time, simply because we are paranoid about customer experience, by the way. So, the first step, as Duston mentioned, is about having the same port to cash experience where they can order NX appliances and it'll get split in the channel via the ST to Nutanix and SuperMicro. So, we hope to continue to keep that experience, even if we end up selling more software than hardware, as we'll do over time. But then the customers can come back and fulfill the hardware by going through a very similar sales process. Even today, we have -- more than 30% of our nodes are actually OEM nodes, and we have tested -- being tested in customer service, customer support. And we've kept our OEM partners honest as well. So, we've actually gone through building that muscle memory of customer support at a nontrivial number of nodes that don't belong to NX nodes.
Duston Williams -- Chief Financial Officer
And I think it's really important also just to really understand that there's absolutely zero change from what the customer sees. So, that process from the customer is left intact and exactly the same as it has been in the past.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
And that being said -- and obviously, we want folks to buy our software and run it on -- like I mentioned, some of our customers run into an OCP-like servers. In fact, others run it on Cisco. Cisco was a pretty good quarter for us this quarter. It substantially jumped from last quarter. HP is also going down a pretty robust path. So, we have really done a good job of building the right tools, all the way from installed tools. We call it Foundation. We have Sizer, which is a capacity-planning tool. We have X-ray, which is our POC automation tool, so it does a lot of the testing of the hardware upfront. We are in the process of actually pushing out our certification tool to all the partners so that they can actually go and certify this in the field itself. So, a ton of automation that was actually done to make sure that the transition from hardware to software is without a lot of these negligent things that one could end up doing, and software with experience. And not only the experience, but product reliability and integrity of data, and things like that.
Simon Leopold -- Raymond James -- Analyst
Great. Thank you for taking my questions.

Your next question comes from the line of Mark Murphy from JPMorgan. Your line is open.
Benjamin -- JPMorgan Chase & Co. -- Analyst
Hi, this is Benjamin sitting in for Mark. Great quarter. Seems like a lot of moving pieces. So, as you -- my question was about the sales motion and how it changes. So, as you move to a software-centric company, and it seems there will be a lot of changes. I don't know if there are changes in the organization structure, but definitely comp will change for the sales guys. How does the sales motion for sales guys change? Is there a learning curve to selling software versus selling the appliances, etc.? And how confident are you that you'll be able -- that we will not see a period of oscillations with respect to bookings in the next 12 months?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
You know, one thing that we've learned in the last couple of years is to segment, segment, segment, our world and our lives. So, if you look at the pyramid, the middle of the pyramid, which is the midmarket, and the base of the pyramid, which is commercial business, we shouldn't see much of a difference. We've been selling OEM nodes with our software for the last couple of years. Our sellers have done a pretty good job of really managing relatively conflicted relationships in a way that hasn't hurt our relationship with the customer, including both sales in terms of professionals services and customer support itself. The top of the pyramid is where we expect to -- especially our global account managers, who have been used to selling software in their past lives as well, to go and do ELAs. And these could be very large ELAs that basically help replatform our customer's overall infrastructure.
So, I think we're going to look at it in that segmented way, and I think that's the way to actually mitigate any risks along the way. But definitely, it's a cultural shift to think about how do you decouple the budget between the software budget and the hardware budget. And many of our folks have actually been thinking on these lines for a while, because it's hard, just the fact that we flipped the switch overnight. And we're talking about this for almost a year now, as we're porting our software to Cisco, or porting our software to HP and IBM, and porting our software to white boxes like OCP-like servers and so on. So, we've done a fairly thorough job in the last 18, 24 months, which is exactly what I told in that script, that this is not something that happened overnight.
Benjamin -- JPMorgan Chase & Co. -- Analyst
Okay, understood. The other question was, Duston, about -- on the software-centric disclosure. I think you mentioned $800 million of software and support if you add on the rate of the pass-through in the last 12 months. What portion of that is recurring today? And how do you think that recurring portion looks in 12 months from now?
Duston Williams -- Chief Financial Officer
Yeah, that's something, again, as far as how that changes and the recurring piece of that, that we need to give some more thought to. And I think maybe at the beginning of year, we'll give some more thought there. We've obviously got a big piece of the support part of the transactions that are obviously all recurring in 95% renewal-plus rate there. And we continue to get more and more of the product portfolio set up that way to reoccur, but yeah, we'll give some insights --
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, the good thing is also that our software additions, STARTER, PRO, and ULTIMATE --they are all term licenses, actually. So, most customers look at one-year, three-year terms, and they buy it with the support lifetime itself.
Benjamin -- JPMorgan Chase & Co. -- Analyst
Okay, got it. I'll cede the floor. Thank you.

Your next question comes from the line of Alex Kurtz from KeyBanc Capital Markets. Your line is open.
Alex Kurtz -- KeyBanc Capital Markets -- Analyst
Yeah. Thanks, guys. Couple quick questions here. Dheeraj, at the beginning of the call, you talked about a hyperscale customer win or running on OCP. I don't know if that was new or not, but maybe you could refresh us on selling your software. Maybe not to the top four hyperscalers, but sort of maybe five through 20, if there's been sort of a development in the pipeline with that customer base?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah. I think one of the things we'll do, Alex, in the coming couple of quarters, is start talking about SaaS customers. We've done some good things with those folks in the past with a great vertical part. But the most exciting thing there is, more than the 15 to 20, is to take our software and put it in the bare metal service in the top four themselves, and they're all willing to open up, including the announcement that Amazon made about three, four days ago about bare metal as a service. That opens up some really good doors for us to go and use them as a platform where we make our software even more invisible than actually shipping systems to their on-prem environment. So, look out for some more SaaS-based insights in the coming quarters.
Alex Kurtz -- KeyBanc Capital Markets -- Analyst
And just a follow up with the moves to software. Have you seen any customers in the top 25 or maybe within the top global 2000 where they've approached you about just purchasing the software directly from you, and then just kind of going on their own as far as burning it onto the hardware?
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah. So, we talked about a couple of these ELAs in the last quarter. In fact, one of the ELAs is a very giant retail chain. It's a Global 1000 company that has taken our software, an ELA version of it, and is running it on both Dell and HP servers, actually. So, a lot of what we did in terms of getting the support from HP was because the customer wanted it. So, we've done some other ELAs with Global 1000 customers in a very similar fashion.
Alex Kurtz -- KeyBanc Capital Markets -- Analyst
All right, thanks, guys.

Your next question comes from the line of Wamsi Mohan from Bank of America Merrill Lynch. Your line is open.
Param Singh -- Bank of America Merrill Lynch -- Analyst
Hi, thank you. So, this is Param Singh on behalf of Wamsi. So, firstly, I was wondering what was your average billing per customer in the quarter? How has that trended? It also looks like the number of new customers that came into your install base was lower than the past few quarters, so maybe you could comment on that as well. Thank you.
Duston Williams -- Chief Financial Officer
Yeah. We've never really given a number on the average, if that was your question, average deal size or customer size there. Yeah, there's too many segments there. You've got the OEM piece, which is obviously lower. You've got Global 2000. That's higher. You've got all this other stuff there. So, we really haven't -- we haven't commented on it. But I think you can take away that with the big deals, that has a tendency to migrate up. And the deeper we get in the Global 2000, obviously, that deal size ends up taking care of itself. But even on ours, the product is built for repurchase also. So, it's a little deceiving there that you don't have to buy these massive amounts of upfront purchases. That's not how the product's designed, obviously. So, you always have a bunch of continuing repeat purchasing there.
On the customer account, yeah, I wouldn't look too much into that. Q1's always little softer from a customer perspective. But we added a decent amount of customers there. In Q2, it will pop up naturally, which it usually does quite a bit from the Q1 level.
Param Singh -- Bank of America Merrill Lynch -- Analyst
And as a follow-up -- I appreciate the clarity you guys gave on the transition there. But if you could talk a little bit about what have you already done in the U.S.? What sales groups are you focusing on? Is it by vertical that have now been moved to kind of passing through the hardware, or is it just that you've opened up across the U.S. right now, and it's just taking time to show up on your P&L? And then, how do you expect to kind of incrementally launch that with your sales teams in the international markets? I'd appreciate any clarity there.
Duston Williams -- Chief Financial Officer
Yeah, again, it's fairly transparent for most things there. And again, it's not -- it has nothing to really to do with verticals or customers or whatever. It's a generic process that we can start executing and eliminating the path through hardware on our books there. So, there's no limitations, if you will, from that perspective. And then, international is just another process there. We just haven't focused on it yet, but it's a similar process. It's a little bit more dispersed, so you lose a little of the concentration. So, maybe it takes a little longer to do some things there. But it's a very similar process that the folks are working on now.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
And in terms of any kind of segmentation to roll this out slowly and gradually, I think we just picked up some large deals and built some muscle memory, and we're just going down that path of deeper down the pyramid.
Param Singh -- Bank of America Merrill Lynch -- Analyst
Okay. And then with SuperMicro, is there anything that they would be doing differently than they are right now with the appliances in the new model?
Duston Williams -- Chief Financial Officer
Just who they invoice. That's all.
Param Singh -- Bank of America Merrill Lynch -- Analyst
Okay, got it. Really appreciate the clarity, guys. Thank you.

Our last question comes from the line of Katy Huberty from Morgan Stanley. Your line is open.
Katy Huberty -- Morgan Stanley -- Analyst
Thank you. Congrats on the quarter. Dheeraj, does deemphasizing the hardware increase your chances of new partnerships, or even the chance that partners like Dell will increase their commitment to selling your solutions versus their own? And then I have a follow-up.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah. I think it definitely it reduces friction in the sales motion, both for our sellers and the OEM sellers themselves. That being said, we also expect fully that the market we will make its decision on whether they want to get end-to-end support from us, or whether they are comfortable actually going through two-hop support. So, I think we have to hustle to prove that either our OEM partners are very good at support, even at scale, or our customers just pick us over going through two hops of support itself. But absolutely, we expect the friction to go down. We don't expect any kind of algorithms that people have to apply to take it through this route to market versus that route to market because there'll be normalized currency for how salespeople will make quota.
Katy Huberty -- Morgan Stanley -- Analyst
Okay. And then at the user conference in June, I think you talked about Xi launching early 2018. Today. you talked about middle of the year. Is that just a function of early release versus GA, or is the timing different? And then maybe you can comment on when you think the memory market loosens, because I know that's been a factor on gross margins. Thank you.
Dheeraj Pandey -- Founder, Chief Executive Officer, and Chairman
Yeah, thank you. I think one of the things, Katy, that we talked about in our overall engineering culture is how this release that we're actually doing in 5.5 took us a little bit longer to come out with in terms of general availability. And that pushes a few other things out as well. So there's, I would say, three months' worth of wait time in Xi, because we have to keep the lights on with on-prem customers as well. And we do expect to actually change the way we do engineering. In these two-piece teams, like really thinking about cloud engineering. What does it mean to have a platoon of developers who are independently releasing code? And it's becoming a company that's more DevOps-like. So, that's the foundation that the company is going through to actually improve our overall fidelity of releases as well.
Katy Huberty -- Morgan Stanley -- Analyst
And Duston, do you have any comments on your thoughts around the memory market?
Duston Williams -- Chief Financial Officer
Yeah. Yeah, as we've said, it's gotten, obviously, better. I don't think there's any insights right now to seeing it actually going the other way as far as pricing goes. It's gotten to a manageable level that we've been doing a good job managing around it, and doing a fine job with margins. And we expect it to be a little bit better this quarter, and then we'll see from there.
Katy Huberty -- Morgan Stanley -- Analyst
