The Linux operating system will account for 29 per cent of units shipped into the worldwide server market in 2008, up from 12 per cent last year, according to predictions published by the IDC research firm.
Linux will take $US9.7 billion from the $US60.8 billion market when measured by revenue, according to IDC. Servers running the Windows operating system will account for $US22.7 billion of the market.
IDC forecast hat the worldwide market for server hardware would grow at 3.8 per cent per year for the next five years, jumping from $US53 billion in 2004 to $US60.8 billion in 2008.
Growth would be strongest in central and eastern Europe and the Asia Pacific region, both of which were expected to grow more than 6.5 per cent, year-over-year, until 2008, it said.
Though Windows systems will account for just 37 per cent of the 2008 server market, when measured by dollars spent, they will account for 60 per cent of the units shipped, a slight drop in market share from the 63 per cent of units shipped IDC reported for 2003.
Sales of blade systems are also expected to grow rapidly, according to IDC.
By 2008, blade shipments are expected to reach $US9 billion, or 29 per cent of server units shipped. Blades accounted for just 4 per cent of the server market in 2003, the research firm said.
