When deploying vSphere with Tanzu on a PowerStore X model, perform the following three steps before enabling Workload Management.
A single PowerStore X model appliance contains two nodes which are deployed as two ESXi hosts. vSphere with Tanzu requires a minimum of three ESXi hosts. Therefore, a minimum of two PowerStore X appliances must be deployed in a PowerStore X model cluster. A two-appliance cluster would yield four nodes or four ESXi hosts, which meets the vSphere with Tanzu minimum requirement of three ESXi hosts
When the PowerStore X model is deployed, by default it sets the cluster DRS Automation Level to Partially Automated. vSphere with Tanzu requires that the cluster DRS Automation Level is set to Fully Automated. Modifying the DRS Automation Level is a feature that was introduced in PowerStore 2.1.
When the PowerStore X model is deployed, by default it sets the Cluster MTU to 1500 bytes. This Cluster MTU setting correlates to the vSphere Distributed Switch MTU which will also reflect the same value of 1500. vSphere with Tanzu requires jumbo frames support with a minimum MTU value of 1600. Dell Technologies recommends configuring the Cluster MTU in PowerStore Manager to the maximum value of 9000 bytes. Once completed, PowerStore Manager will automatically configure the Distributed Switch with the same MTU value of 9000 bytes.
Note: Configuring MTU of the Distributed Switch outside of PowerStore Manager is not recommended and will result in Alerts being generated in PowerStore Manager.
