PowerFlex has implemented VMwares vSphere API for Storage Awareness (VASA). PowerFlexs VASA enables control of PowerFlex storage to be handled by the vCenter administrator. PowerFlexs VASA uses Virtual Volumes (VVols) to enable VMs hosted on VMware vSphere to have their storage mapped directly to storage in PowerFlex.

PowerFlexs VASA automatically assigns VMware storage policies based on keywords
that appear in the PowerFlex Storage Pool names.

PowerFlexs VASA runs on a separate VM that needs to be deployed.

Dell EMC PowerFlex is currently not listed in the VMware Compatibility Guide for VVOL support.
