When you deploy the vCenter Server appliance, the ESXi host or DRS cluster on which you deploy the appliance must meet minimum storage requirements. The required storage depends not only on the size of the vSphere environment and the storage size, but also on the disk provisioning mode.

Storage Requirements for the vCenter Server Appliance

The storage requirements are different for each vSphere environment size and depend on your database size requirements.

Table 1. Storage Requirements for a vCenter Server Appliance
Default Storage Size Large Storage Size X-Large Storage Size
