EMC Symmetrix DMX-4: Supported Drive Types


In this blog post we will discuss the supported drive models for EMC Symmetrix DMX-4. Right before the release of Symmetrix V-Max systems, in early Feb 2009 we saw some added support for EFD’s (Enterprise Flash Disk) on the Symmetrix DMX-4 platform. The additions were denser 200GB and 400GB EFD’s.

The following size drives types are supported with Symmetrix DMX-4 Systems at the current microcode 5773: 73GB, 146GB, 200GB, 300GB, 400GB, 450GB, 500GB, 1000GB. Flavors of drives include 10K or 15K and interface varies 2GB or 4GB.
The drive has capabilities to auto negotiate to the backplane speed. If the drive LED is green the speed is 2GB, if its neon blue its 4GB interface.
