—According to estimates released this week by Gartner Inc., EMC held on to its number-one position in the external controller-based disk array market in the second quarter of this year—by a long shot. EMC had a 23.8% market share based on revenues, according to Gartner, and increased its revenues by 4.3% versus the second quarter of 2005. (In Gartner's calculations, EMC's revenues do not include revenues from its major resellers, Dell and Fujitsu Siemens.)

The number-two spot was a virtual tie between IBM and Hewlett-Packard, both of which posted a 14.6% market share on Q2 revenues of $526.7 million. IBM got there by increasing revenues by 4% year-over-year, while HP's revenues increased by only 1.5% to land the company in the tie for second place.

Hitachi maintained its number-four position with an 8.3% market share and increased its revenues by 5.8% over the previous year. (Gartner's estimates of Hitachi's revenues exclude revenues from its primary resellers, HP and Sun.)

Sun edged out Dell (7.5% market share) and Network Appliance (also at 7.5%) in the number-five spot with a 7.6% market share, although Network Appliance posted the strongest growth among the top-tier vendors with 22.2% revenue growth.

Sun posted 13.8% revenue growth vs. the previous year, although Donna Taylor, a principal analyst with Gartner, notes that Sun's revenue growth was attributable primarily to its acquisition of StorageTek last year.

The top-seven vendors accounted for 84.1% of the overall market for external disk arrays, while revenues for the "other" vendors declined 4.9% in the second quarter.

The overall market for external controller-based disk arrays totaled $3.6 billion in the second quarter—a 4.3% increase over the same period a year ago.

Gartner analysts will present detailed analysis of the storage industry at two upcoming conferences: The Gartner Symposium/ITxpo in Orlando, October 9–13, and the 25th Annual Data Center Conference in Las Vegas, November 28–December 1. For more information, go to www.gartner.com.
