Before you enable vSAN on a cluster and start using it as virtual machine storage, provide the infrastructure that is required for correct operation of vSAN. Selecting or Verifying the Compatibility of Storage DevicesAn important step before you deploy vSAN is to verify that your storage devices, drivers, and firmware are compatible with vSAN by consulting the VMware Compatibility Guide. Preparing StorageProvide enough disk space for vSAN and for the virtualized workloads that use the vSAN datastore. Providing Memory for vSANYou must provision hosts with memory according to the maximum number of devices and disk groups that you intend to map to vSAN. Preparing Your Hosts for vSANAs a part of the preparation for enabling vSAN, review the requirements and recommendations about the configuration of hosts for the cluster. vSAN and vCenter Server CompatibilitySynchronize the versions of vCenter Server and of ESXi to avoid potential faults because of differences in the vSAN support in vCenter Server and ESXi. Preparing Storage ControllersConfigure the storage controller on a host according to the requirements of vSAN. Configuring vSAN NetworkBefore you enable vSAN on a cluster and ESXi hosts, you must construct the necessary network to carry the vSAN communication. Considerations about the vSAN LicenseWhen you prepare your cluster for vSAN, review the requirements of the vSAN license.
