HOPKINTON, Mass.--(BUSINESS WIRE)--April 4, 2002

EMC Led Software Market for Third Straight Year;

Also #1 in Rapidly Growing Data Replication and Resource Management

Software Segments

EMC Corporation continued to widen its lead as the world's #1 provider of storage management software in 2001, according to a new report from Gartner Dataquest.(a) EMC led the $4.9 billion market last year with 30.4% revenue share in 2001, outpacing the closest competitor by more than 10 percentage points. According to the report, EMC also led the two fastest-growing storage management software segments, Storage Infrastructure and Enterprise Resource Management, which Gartner Dataquest predicts will together represent over 70% of the total storage management software market by 2006.(b)

According to Gartner Dataquest, EMC was #1 in Data Replication software revenue in 2001, leading the sub-segment with 55% share - five times larger than the next competitor (see today's related release, "EMC Led 2001 Data Replication Software Market By Wide Margin, According To New Report").

Gartner Dataquest's new report ("2001 Storage Management Software Market Share") partitioned the storage management software market into three segments - Storage Infrastructure (which includes Data Replication), Enterprise Storage Resource Management, and Data Management Products software.

In Storage Infrastructure Software, EMC led with 45.5% share, more than three times the share of its closest competitor, according to Gartner Dataquest. In 2001 the Storage Infrastructure Software segment was the largest of the three segments and includes load balancing software such as EMC PowerPath, data mobility software such as EMC HighRoad, and data replication solutions such as EMC SRDF (Symmetrix Remote Data Facility), EMC TimeFinder, EMC MirrorView and EMC SnapView.

According to Gartner Dataquest, EMC led the Enterprise Resource Management Software (ESRM) segment in 2001 with 51.7% share, a gain of nearly 10 percentage points over 2000 and nearly five times the share of its closest competitor. According to Gartner, the second fastest growing storage management software segment provides for the management of various storage resources on the network. The segment includes open management software, such as EMC ESN Manager and EMC StorageScope, and EMC ControlCenter, the bedrock of EMC's Auto IS strategy.

Carolyn DiCenzo, chief analyst for Gartner Dataquest, said, "While disk array growth stalled in 2001, software continued to deliver growth as companies looked to improve the security and management of information storage. Storage Management Infrastructure products grew 15% last year, fueled by demand for data replication software used to safeguard corporate assets. Storage and Device Resource Management software also grew in 2001, reflecting market demand for better, more functional networked storage management tools."
