Unix servers saw a 23.4 percent revenue decline in the third quarter of 2009 (Q309) compared to the same time period in 2008, according to market research IDC.
Global Unix revenues were $2.8 billion for the quarter, representing 26.9 percent of quarterly server spending.
IBM gained 5.1 points of Unix market share year-over-year and holds the Q3 leadership position, posting 39.5 percent share in this segment, followed by Hewlett Packard (29.2%) and Sun Microsystems (23.4%), respectively.
Microsoft Windows server revenue was $4.5 billion in Q309 showing a 12.8% year-over-year decline and comprising 43.0% of all server revenue in the quarter. Windows servers account for the single largest segment, by operating system, in the worldwide server market.
Linux server revenue declined 12.6% year over year to $1.5 billion in the quarter. Linux servers now represent 14.8% of all server revenue, up slightly from 14.0% a year ago.
Worldwide server market declined 17.3 percent year-over-year to $10.4 billion in Q3. Although it was the fifth consecutive quarter of year-over-year revenue decline, the market grew sequentially for the first time since Q408.
“The worldwide server market exceeded expectations in the third quarter with improving x86 server demand leading the way, which was driven in part by the infrastructure refresh momentum that is building in many geographies. In fact, x86 server revenues experienced their largest sequential quarterly revenue increase in nearly five years,” said Matt Eastwood, group vice president of Enterprise Platforms at IDC.
“IDC believes that platform migration is once again gaining steam in the market and the post-recession server deployment patterns will establish the technology agenda in the datacenter for the next business cycle. For server vendors, after five quarters of market contraction, the next few quarters will be critical to determining the technology platform winners and losers in the years ahead.”
