IBM tossed Sun Microsystems aside as market-share leader in US server sales for the first quarter of 2001, according to research firm Dataquest, a division of Gartner.
Sun first overtook IBM as the US server sales leader in 2000, sparking a bitter public relations battle between the vendors. Worldwide, the server market has been stagnant for the past year: Dataquest charted sector-wide revenue of $US12.04 billion for the quarter, down 1.8 per cent from first-quarter 2000's revenue total of $12.26 billion.
Globally, IBM remains comfortably ahead of Sun, its nearest rival. Both companies slightly increased their worldwide market share during the first quarter. IBM's market share climbed to 26.8 per cent, up from 26 per cent in the year-ago quarter. Sun's share increased to 17.3 per cent, from 17 per cent.
Third-place Compaq also saw its market share grow, to 13.9 per cent from 12.6 per cent, displacing fourth-place Hewlett-Packard. HP suffered a market-share decrease in the first quarter to 12.7 per cent, down from 14.1 per cent in the year-ago quarter.
