The Australian server market slowed to 5 percent growth in the second quarter with Sun and AMD-based systems the only standouts, according to IDC\u2019s quarterly server tracker.Chris Ward, IDC Asia Pacific servers and workstations market analyst, said this quarter\u2019s growth rate was a slowdown on last quarter\u2019s 20 percent, because most of the vendors are trying to sell more higher-value, two- and four-way systems.Local enterprises spent US$130 million in Q2, which is normally a stronger quarter, Ward said.The significant standout was Sun, which was the only Unix server vendor to grow its revenue\u2014by more than 30 percent."Sun went well in the Unix [Solaris on Sparc] server space and was the only Unix vendor to grow in revenue while IBM and HP did not," Ward said.Ward said that since Sun launched its galaxy range of x86-64 systems, its business has been the fastest growing in that space at 83 percent, but it is coming off a small base and is still languishing at number five in terms of x86 units shipped.The other trend of note was that AMD almost doubled its shipments from\u00a0the first quarter\u00a0to the second, mainly due to "large orders across sectors.""In the x86 space, AMD surpassed 20 percent revenue share in the market and the rest is taken up by Intel," Ward said, adding that Sun and HP were the only vendors to offer a range of AMD-based products."IBM had a moderate quarter and was pretty much flat, [but] has seen stronger growth in low-end Unix products, including OpenPower."Both Dell and HP had a strong quarter in terms of units shipped, but their revenues were generally flat compared with the same time last year.Ward said the Unix market is declining with migrations of industry standard servers, but this trend has been slower than the previous year."The market is heading to dual-core, which will proliferate, but we haven\u2019t seen massive deployments yet," he said. "Intel\u2019s Woodcrest is expected to be adopted quite quickly as it is coming to market at a comparable price. "AMD is challenged by Woodcrest, so there will be increased competition between the two and customers will benefit."Sun Microsystems\u2019 Australia and New Zealand Solaris product manager, James Eagleton, said the company gained 7 percent in market share across all markets, which can be attributed to "innovation and sense of vibrancy around Solaris.""We\u2019re seeing a lot of traction around Galaxy now and have launched the Opteron Rev-F capability," Eagleton said. "More blade offerings are coming before the end of the year, so we\u2019re only partway along our journey into x86."Eagleton said its Niagara-based Ultrasparc T1 systems are competing well against Intel\u2019s Itanium, with more than 250 units shipped in the last quarter compared with 142 IA64 units, according to Gartner.
