HOPKINTON, Mass.--(BUSINESS WIRE)--Dec. 4, 2003

EMC Corporation (NYSE:EMC) announced today that more than 300 partners and resellers have enrolled in the EMC Centera partner program since its inception, with more than 30 joining since October 2003. As an outgrowth of this momentum, more than 85 applications have been integrated with Centera and are generally available. An additional 140 partners are currently engaged in the integration process, taking advantage of the free and open Centera application programming interface (API).

As a result of this success, through the third quarter of this year, more than ten petabytes (10,000 terabytes) of Centera have been shipped to customers since its introduction in April 2002.

Centera's rapid adoption highlights its position as the fastest-growing storage platform in EMC history and underscores its role as a critical component of EMC's information lifecycle management (ILM) strategy. More than 400 customers have implemented the Centera platform for its unique data protection, self-healing and long-term archiving capabilities.

EMC also announced plans to double its investment in the Centera Partner Support Program, in 2004. These incremental resources will help EMC continue to deliver the industry's highest levels of partner support for key market leaders.

Joe Tucci, EMC President and CEO, said, "As with any business endeavor, success for Centera is a team sport. The power of Centera is brought to life for customers only through solid partnerships with the world's leading fixed-content application providers. We continue unwavering support for our partner efforts in the development and adoption of open Centera solutions for our mutual customers."

Key Centera partners include some of the world's leading application providers and resellers including AGFA, Connected, Documentum, FileNet, IXOS, Fujitsu Siemens, GE Medical, KVS, LEGATO, Mobius, Unisys and many others.

Mike Hedger, CEO of KVS, said, "KVS delivers market-leading e-mail archiving solutions. Our customers demand not only cost-effective products, but focused and open solutions. To meet their demands, we work with partners who share our vision. This desire to make our customers succeed serves as the foundation of our premium partner relationship with EMC and fuels the continued successful integration of KVS with the Centera platform."

Helmut Beck, Vice President, Storage Solutions at Fujitsu Siemens Computers, said, "Our mission is to offer to our customers the world's best-in-class storage solutions. Reselling Centera is an important element of this commitment. The mutual partnerships among major application providers, EMC and Fujitsu Siemens Computers give us all the options we need."

Chander Khanna, Vice President, Platform Marketing at Unisys Corporation, said, "As a reseller, Unisys looked for a partner with flexibility in storage options. EMC Centera, coupled with some Unisys applications, provides our clients with choices few others can offer. Our clients, particularly in the financial services and check-imaging industries, appreciate EMC's market presence and the breadth this product line offers."

Charles King, Research Director at The Sageza Group, said, "Centera's partner acceptance and support reflects EMC's outreach to the ISV community. This bodes well for the company, its partners and its customers."
