If you doubted the dominance of IBM's grip on the server market, doubt no more. Big Blue has maintained its market share lead in blade servers as well as the more traditional variety, according to a pair of market research reports just released.

IBM raked in the most server revenue in the last quarter for the tenth consecutive quarter ending October, said market researcher Gartner, with growth in overall, Unix and blade server revenues. Its overall share was 32.7 per cent, up nine per cent year-on-year.

Breaking that down, IBM's blade server revenues grew 82 per cent year-to-year, according to both Gartner and rival researcher IDC, to take more than 45 percent of blade server revenues in the third quarter - although IDC's figures put that share slightly lower at 42 per cent.

Big Blue's also taken the leader spot in overall Linux-based server revenue worldwide in 3Q05, with 29.7 percent of the revenue, up 32 per cent year-on-year. In particular, eServer iSeries system revenue was up 25 per cent year-on-year.

And finally, IBM increased its Unix server revenue share, growing 3.7 points year-to-year, taking 29.4 per cent of the market. IDC reported that IBM's Unix server revenues grew by 11.1 per cent in the last year.
