Uncertainty about Sun Microsystems' future appears to have contributed to serious erosion in the company's market share for computer servers in the latest quarter, according to new data being released Wednesday.
The latest numbers from market-research firm IDC show that Sun's market share in servers stood at 10 percent in the second quarter, down more than a full percentage point from the same period last year.
Sun is the world's No. 4 maker of computer servers, which power Web sites and corporate back offices.
Rivals have siphoned off business by stoking fears about the future of Sun's product lines under Oracle , which has agreed to buy Sun for $7.4 billion but has been prevented from completing the deal because of antitrust scrutiny in Europe.
Rivals IBM and Dell gained market share in the latest quarter, to 34.5 percent and 12.4 percent, respectively. Hewlett-Packard's market share dipped slightly to 28.5 percent. It was the toughest quarter for the server industry in 13 years, according to IDC.
