DMX
TM
systems are EMC’s family of high-end
storage solutions. The DMX-3 model establishes a new performance
and capacity trajectory for the highest of the high-end enterprise
systems.
The DMX-3 offers 4 Gb/s front-end that provides increased
performance without increasing power and cooling.
The DMX-3 fully leverages the EMC industry-leading storage
management functionality and introduces the economic benefits of
scalable packaging to the high-end storage market.
The Symmetrix
®
DMX-3 is incrementally scalable, supporting from
96 to 1,920 2 Gb/s high-performance Fibre Channel disk drives,
providing a maximum raw capacity of approximately 1 PB.
Note: For information on 2,400 drive support, contact your EMC Sales
Representative.
To support the massive scalability of DMX-3 configurations, the DMX
architecture has been expanded and improved to deliver higher
throughput (1 GB/s links) and increased I/O performance (four dual
1.3 GHz PPC processor complexes per director). Table 1 on page 26
describes some of the Symmetrix DMX-3 performance features.
