wyhlg

The best is yet to come...
From
its inception, Symmetrix was designed with the flexibility to
incorporate the latest technology in disk drives, memory and other
components. This effort has enabled the storage platform to evolve to
meet the ever-increasing data demands of enterprises. and has provided
customers with unparalleled investment protection. The first-generation
Symmetrix 4400 Integrated Cached Disk Array (ICDA), with a total
capacity of 24 gigabytes, was introduced in 1990. The
seventh-generation system, the Symmetrix DMX-3, was introduced in July
2005 and features a Direct Matrix Architecture® and maximum capacity of
one petabyte (1,024 terabytes). The Symmetrix platform has continued to
improve and evolve to meet the needs of data-intensive organizations
worldwide and remains the most successful intelligent storage platform
in history.
    With
more than 68,000 systems shipped from its introduction in 1990 through
the end of June, 2005 and with more than 400 EMC patents covering its
technology, Symmetrix remains the high-end storage market leader and
continues to set the standard for mission-critical high-end storage
innovation.
