For the VI workload domains that you deploy with your Cloud Foundation on VxRail instance, the VxRail clusters support the following options for provisioning primary storage resources to support virtual machine operations:
- Purchase VxRail nodes with installed disk drives, and then use the disk drives on the VxRail nodes for the formation of a vSAN datastore.

Figure 18. Local vSAN datastore for supporting VI workload domains
- Order VxRail nodes without disk drives, and obtain vSAN storage resources from another VxRail cluster configured with a vSAN datastore. This option requires that a VxRail cluster with sufficient vSAN storage resources is already deployed in the data center to support a VI workload domain.
Figure 19. Remote vSAN datastore mounted to support VI workload domains
This option requires configuring the physical network infrastructure so that the vSAN networks on both clusters can communicate before attempting to mount a remote vSAN datastore.
- Order VxRail nodes without disk drives, but have adapter cards installed to connect to an external storage array in your data center. Before deployment, the storage area network must be configured so that the VxRail nodes can discover the LUNs on the storage array. A minimum of one LUN must be configured on the storage array for the VxRail cluster to use as a VMFS datastore.
Consult with your Dell Technologies account team for the storage products that are compatible with Cloud Foundation on VxRail.
