The following figure illustrates the logical view of the Greenplum on PowerFlex with ten storage only (SO) nodes and 12 compute only (CO) nodes. The Greenplum is deployed on the CO nodes with one instance of master and ten segments.
Each of the SO node is fully populated with ten 7.68 TB SAS SSD drives. From PowerFlex storage layout perspective, a single PowerFlex cluster with two protection domains is used. Since each of the PowerFlex node is fully populated with ten disks, these 100 disks are used to create four storage pools from which the various volumes are created. The 12 CO nodes which are the ESXi hosts has the SDC component that makes the ESXi data stores available from the PowerFlex volumes. Once the data stores become available, Greenplum VMs are created in the VCenter with a single master and ten segments.
