Worldwide server shipments totalled 1.08 million units in the second quarter of 2002, up 0.5% over the same quarter last year.
US shipments reached 482,647 units, up 9.9% on the same period a year ago.
However, this does not necessarily signal the end of the market downturn, because the market overall has yet to show consistent revenue growth, Dataquest said. Without a stable revenue stream, companies may not be able to invest in new server equipment.
A weak business environment worldwide means that purchasing decisions, platform changes and big contract signings are all being deferred.
The merger of Hewlett-Packard and Compaq Computer moved the new HP into first place in worldwide and US rankings, despite HP alone selling less than last year.
HP holds 30.5% of the worldwide server market and 26.8% of the US market.
Dell comes second with 18% of market share worldwide and 24% in the US, followed by IBM, which holds14.5% worldwide and 13.3% in the US.
Sun Microsystems comes fourth with a 6.5% worldwide share, and a US share of 7.5%
Fifth place is held by NEC, which holds a 2.2% of the market share worldwide, but Gateway holds the same position in the US with 1.1% market share.
