EMC Launches World's Largest-Capacity Disk Storage System, Able to Hold 100 Million U.S. Income Tax Forms.

HOPKINTON, Mass.--(BUSINESS WIRE)--April 6, 1998--

World's Highest-Capacity Disk Storage System Packs

Six Terabytes (Six Trillion Bytes) in 17.3 Square Feet

EMC Corporation, the world's leading provider of intelligent enterprise storage systems and software, today introduced a new system capable of storing the equivalent of 100 million Form 1040 Individual Income Tax Return Statements -- the entire number of annual 1040 statements due next week to the Internal Revenue Service.

Through the use of up to 128 47-gigabyte disk drives in a single system, EMC today doubled the capacity of its high-end Symmetrix 5700/3700 Enterprise Storage system, delivering a record six terabytes (six trillion bytes) of storage capacity in 17.3 square feet of floor space. The new system is the highest capacity disk storage system in the world and the first to implement the new 47-gigabyte drives. Six terabytes is the equivalent of the amount of information in 120,000 four-drawer filing cabinets; 102,000 CD-ROMS; and 3 million standard diskettes.

This announcement breaks new ground in the ability of EMC Enterprise Storage to scale up with -- and provide unrivaled information management, protection and sharing for -- the increasingly aggressive storage needs of today's data-intensive applications.

"The record capacities announced today illustrate EMC's role in helping businesses take control of the information juggernaut and use its momentum to their advantage," stated Robert Dutkowsky, EMC Executive Vice President, Markets and Channels. "As the amount of information considered business-critical grows beyond anyone's forecasts, EMC Symmetrix will continue to be the industry's premier open platform for high-performance, consolidated storage for all types of information across the enterprise."

Chicago-based U.S. Cellular is America's eighth largest wireless services provider. Dave Dubnick, U.S. Cellular's Director of Infrastructure and Operations, commented, "Our need for data is growing larger by the day. The more data we can support in a single storage system, the better we're able to manage the customer billing, data warehouse and other applications that drive our business. The new 6-terabyte Symmetrix -- combined with EMC's enterprise storage software and its ability to handle storage requirements for all of our Hewlett-Packard, Sun, IBM RS/6000 and Windows NT servers simultaneously -- further differentiates EMC from anyone else out there."

According to International Data Corporation (IDC), the need for storage capacity will continue to increase at a compound annual growth rate of more than 95% through the end of the decade.

John McArthur, Director of Storage Systems Research, IDC, commented, "The efficiencies gained from advances in disk density will help EMC satisfy its customers' demand for greater and greater amounts of storage. This announcement builds on EMC's ability to support large-scale data consolidation efforts and an increasing number of data-hungry applications."

To date, EMC has shipped more than 12 petabytes (12,000 terabytes) of capacity on its Symmetrix family of intelligent storage systems, more than any disk storage system in history. Symmetrix systems are used by many of the world's leading organizations -- including the world's 20 largest telecommunications companies and all 25 of the largest banks in the United States -- for the demanding storage requirements of very large database (VLDB), data warehouse, Internet, and other information-intensive applications.

The new high-capacity Symmetrix 5700/3700 systems are available immediately. The systems continue to provide simultaneous connectivity to all major mainframe, UNIX, NT, AS/400 and other hosts, and support all EMC information protection, information management and information sharing software solutions. Configurations up to six-terabytes are available for specific application requirements. U.S. list prices for Symmetrix 5700/3700 systems with new 47-gigabyte drives range from one $1,000,000 to $4,700,000.
