Strong Demand Sustains Worldwide Growth for Storage Software Market, According to IDC

FRAMINGHAM, MA – DECEMBER 11, 2006 – The worldwide storage software market experienced its 12th consecutive quarter of year-over-year growth in the third quarter of 2006 with revenues of $2.5 billion, a 10.7% increase over the same quarter one year ago. According to IDC's Worldwide Quarterly Storage Software Tracker, storage replication was once again a major factor driving the sector's growth.

"The market for storage software has performed very well over the past three years with the replication and archiving segments providing a lot of momentum," said Rhoda Phillips, research manager for Storage Software at IDC. "IDC expects this trend to continue as companies focus on data retention requirements and business continuity needs, as well as storage consolidation and migration issues."

Storage replication, one of the largest storage software markets, demonstrated year-over-year growth of 22.5% in 3Q06. Meanwhile, the smaller but fast-growing archive and hierarchical storage management (HSM) market posted a 30.8% year-over-year growth rate.

EMC led the overall market this quarter with 28.5% revenue share in the third quarter of 2006. Symantec took the second position with 17.6% revenue share, while IBM finished in the third position with 12..3% revenue share. Network Appliance finished in the fourth position with 9.4% revenue share. Again, CA and HP rounded out the top 5 in a statistical tie with 5.3% and 4.9% revenue share, respectively.
