The PowerFlex software-defined storage is configured in a VMware vSphere environment and deployed with a single-layer Hyperconverged Infrastructure (HCI) architecture option. An HCI configuration has both the Storage Data Client (SDC) and Storage Data Server (SDS) configured on each node of the cluster as shown in the following figure.
The Storage Data Server (SDS) aggregates the raw local storage in a node and assists as PowerFlex storage. A single protection domain is carved out of the SSD drives on the four PowerFlex HCI nodes. A single storage pool is configured, and multiple volumes are created to meet the SingleStore requirements. These volumes are mapped to the ESXi cluster and added as a datastore. These are later mapped as disks drives to SingleStore virtual machines using VMware Paravirtual SCSI (PVSCSI) adapters.
