configuration The Symmetrix DMX system can support up to eight slots in the
midplane dedicated to global memory and 512 GB of global memory
(256 GB effective) global memory. Individual global memory
directors are available in 8 GB, 16 GB, 32 GB, and 64 GB sizes.
When configuring global memory for the Symmetrix DMX systems
follow these guidelines:
◆
Very large eight disk director configurations may be limited or
restricted by currently available Symmetrix DMX-3 maximum
memory.
◆
Global memory directors can be added to the DMX-3 not to
exceed the maximum designed for the system’s configuration.
◆
Global memory directors must be configured in pairs of the same
capacity.
