Storage Services

  • For the VI workload domains you deploy with your Cloud Foundation on VxRail instance, the VxRail clusters support options to select from for provisioning primary storage resources to support virtual machine operations.

    • One option is to purchase VxRail nodes with installed disk drives, and then use the disk drives on the VxRail nodes to create a vSAN datastore.

    This figure shows local vSAN datastore to support VI workload domains.

    • Another option is to 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.

    This figure shows a remote vSAN datastore 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.

    • A third option is to 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 about storage products that are compatible with Cloud Foundation on VxRail. See also the VCF On VxRail Architecture Guide.
