Storage-providing nodes

PowerFlex hyperconverged nodes

PowerFlex hyperconverged nodes are based on Dell PowerEdge R660, R760, R650, R750, R640, R740xd, and R840 servers. PowerFlex is deployed on these nodes in a true hyperconverged form where PowerFlex SDC and SDS software components are installed on the same PowerFlex node. PowerFlex hyperconverged nodes nodes provide and consume storage.

PowerFlex storage-only nodes

PowerFlex storage-only nodes are based on Dell PowerEdge R660, R760, R650, R750, R640, R740xd, and R840 servers. PowerFlex storage-only nodes are designed to provide storage capacity but no compute power to the compute cluster. Only the SDS component of the PowerFlex runs on PowerFlex storage-only nodes. PowerFlex storage-only nodes run an embedded operating system and do not require any VMware ESXi license. PowerFlex storage-only nodes have the ability to add additional storage capacity to a PowerFlex cluster without additional compute power.
