Dell PowerFlex Manager 4.6.x CLI Reference Guide

By default, the RMcache size is set to 128 MB in all SDSs. The amount of RAM you can allocate for cache is limited by the amount of RAM on the SDS server:

• If the RAM is less than 32 GB, 50 percent of memory can be used for cache.
• If the RAM is more than 32 GB, 75 percent of memory can be used for cache.

The maximum amount of RAM cache is 128 GB.
