The PowerFlex software-defined infrastructure 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 40 SSD drives on the five PowerFlex HCI nodes. Each host is populated with eight 1.92 TB SSD drives. A single storage pool is configured, and multiple volumes are created to meet the SingleStore needs. These volumes are mapped to the ESXi cluster and added as a datastore.
The SingleStore Cluster VMs are deployed onto these datastores, which consist of two aggregator and multiple leaf VMs. These are later mapped as disk drives to the SingleStore virtual machines using VMware Paravirtual SCSI (PVSCSI) adapters.
