The proof is in the numbers, dearest Fool;
A rising Sun came up against a slow --
a lesser uptake of its hardware tools;
It's elsewhere that the customers do flow.

The numbers are in, and it looks like Sun Microsystems (NASDAQ:SUNW) is tumbling into the end of its fiscal year. Sales and operating earnings came in at the low, low end of official guidance, making the stated goal of 4% operating margins by next quarter seem a bit further away. I'd do this report in iambic pentameter, but there's just no time; enjoy the end of National Poetry Month.

CEO Jonathan Schwartz mentioned that software and services were doing well and validating Sun's business model, but tellingly omitted any mention of the hardware side. Sun used to be the big dog in the Unix server market, at least as commanding a presence as IBM (NYSE:IBM) and Hewlett-Packard (NYSE:HPQ). These days, the server segment is fighting just to keep up with its rivals, turning first to AMD processors when the SPARC wasn't selling, and then to Intel (NASDAQ:INTC) when that platform started looking good.

Of course, the competition has long offered both of those alternatives for many years, although IBM still ties its AIX platform to the proprietary POWER chips. Is the turncoat strategy really paying off for Sun? The Intel option is too new to get a read on, and the Opteron is currently not perceived as a top performer, so it's hard to get a read on the effectiveness there.

In general, I wouldn't be surprised to see Sun phasing out its hardware operations over time -- first the in-house processor design and then perhaps even system integration. Solaris and Java look like the future, and it's much easier to achieve efficient operations in software than in hardware.

In the short term, even that strategy seems tenuous at best. Businesses are starting to get comfortable with the idea of Microsoft's (NASDAQ:MSFT) Windows Vista in their data centers, and the likes of Red Hat (NYSE:RHT) and Novell (NASDAQ:NOVL) are pushing hard to replace Unix with Linux. We'll just have to wait and see where Sun fits into that market flow.
