Sun Microsystems, which has been undergoing a drastic realignment of its server business over the past couple of years, in the second quarter regained its position as the worlds third-largest systems maker, overtaking rival Dell.
The Santa Clara, Calif., company saw its market share increase to about 13 percent in the second quarter, according to numbers released by analyst firms IDC and Gartner.
In the second quarter of 2005, Suns market share stood at between 11 and 12 percent.
In addition, Sun was the only one of the four top server makers to see growth in its revenues. The companys server revenues grew 13.7 to 15.5 percent year to year, according to the firms. IBM, Hewlett-Packard and Dell saw revenue declines of between 1.3 and 3.8 percent.
"[Sun officials] spent the better part of the last few years refreshing a significant portion of their line," said IDC analyst Matthew Eastwood, in Framingham, Mass. "Theyve also done a nice job of stabilizing their core base, going out and educating their customers about the road map and new products."
Sun until two years ago had long shunned the x86 space in favor of its own RISC-based SPARC line. In a turnabout, Sun adopted Advanced Micro Devices Opteron processor as the basis for a new line of x86 systems and has aggressively grown out its product line. The bulk of the companys server business is still the UltraSPARC line, but Eastwood said he expects that the Opteron systems will continue to grow in significance.
In July, Sun added to its line of Opteron-based Galaxy systems, introducing a blade server and a system than can scale to 16 processors.
"We have our foot firmly on the accelerator and are leaving our competitors in the dust," John Fowler, executive vice president of Suns systems group, said in a statement. "Over the past year weve brought to market a significant number of new products—including x64, UltraSPARC IV+ and Sun Fire CoolThreads servers—and the customer response has been overwhelmingly positive."
The AMD relationship has been good for both companies. The Sunnyvale, Calif., chip maker continues to gain traction in a business dominated by rival Intel, with Opteron accounting for 20.2 percent of all x86 server revenue worldwide in the second quarter, according to IDC.
In addition to the Opteron push, Sun also last fall unveiled the UltraSPARC T1 processor, a chip that offers up to eight cores and runs on a power envelope of about 70 watts. With both that chip and its adoption of Opteron, Sun has been pushing to become a leader in the growing movement for more energy-efficient data center technologies.
It also is undergoing dramatic change internally. Jonathan Schwartz has taken the reins from longtime CEO Scott McNealy and has initiated a number of programs, such as cost-cutting measures that will mean up to 5,000 job losses and the merging of its two server lines.
The moves are having a positive effect, IDCs Eastwood said. "There was a period of arrogance in the earlier part of the decade," he said. "Then there was a period of indifference. … Now theyre listening much more closely to their customer base."
In the overall server market, IDC saw unit shipments grow 8.3 percent in the second quarter, the eighth consecutive quarter of slowing growth that the firm attributed in part to the rising prominence of virtualization and multicore processing technology. Revenue grew 0.6 percent, to $12.3 billion. The driving force in the revenue growth was the volume server segment, which at 6.2 percent was the only segment to see growth. The midrange market revenue dropped 3.5 percent, and the high-end 6.9 percent.
Gartner saw a more significant growth in shipments of 12.8 percent, with revenue jumping 2.5 percent.
Linux servers, which saw revenue grow 6.1 percent to $1.5 billion, represent 12 percent of all server revenue, and shipments jumped 9.7 percent, according to IDC. Unix revenue and shipments both declined, 1.6 and 1.8 percent, respectively. Windows server revenue increased 3.1 percent, and shipments rose 11 percent.
Servers running Intels Itanium processor saw revenue increases of 36.4 percent, to more than $740 million. HP, of Palo Alto, Calif., sells more than 80 percent of all Itanium systems. Itanium servers account for 11.7 percent of all non-x86 server revenue.
Gartner, of Stamford, Conn., combined the Unix and Itanium server markets, and noted that revenues grew 2.6 percent and shipments 1.8 percent.
Blade servers continue to be a hot commodity, with revenue growing 37.1 percent and shipments jumping 29.7 percent in the quarter.
In both the IDC and Gartner reports, IBM, of Armonk, N.Y., stayed atop the server market, followed by HP.
