There are several best practices for provisioning storage from a PowerStore appliance to an external vSphere cluster. The size of VMFS datastores and the number of virtual machines that are placed on each datastore can affect the overall performance of the volume and array.
Virtual machines running in PowerStore X model internal nodes use internal vVol storage by default. However, the PowerStore X model can simultaneously run VMs on internal nodes and serve storage to external ESXi hosts. Therefore, the VMFS datastore sizing and virtual machine placement strategies in this section only apply when using PowerStore as storage to external ESXi hosts.
