Dell PowerFlex 4.5.x Technical Overview
Acceleration pools
Acceleration pools enable NVRAM required for fine granularity (FG) storage pools.
NVRAM acceleration pools features and requirements:
- Must reside on NVDIMM devices
- The NVDIMM must be mapped to a DAX Device
- NVRAM acceleration pools cannot be disabled
- Migration to a different NVRAM pool is not supported
Limitation: NVDIMM failure on SDS node causes failure of all SSDs in the FG storage pool for that node.
