Dell PowerFlex 4.6.x Technical Overview
Acceleration pools
Acceleration pools require non-volatile random-access memory for fine granularity storage pools.
Non-volatile random-access memory acceleration pool features and requirements:
- Must reside on SDPM or NVDIMM devices.
- The SDPM or NVDIMM must be mapped to a DAX device.
- Non-volatile random-access memory acceleration pools cannot be disabled.
- Migration to a different NVRAM pool is not supported.
Limitation: SDPM or NVDIMM failure on SDS node causes failure of all SSDs in the fine granularity storage pool for that node.
