VMware Cloud Foundation on VxRail has flexible storage options that include vSAN and Fibre Channel storage (introduced in VCF 4.3.1) as primary storage options for a VI WLD. The Management WLD primary VxRail cluster still requires vSAN storage as its primary storage. iSCSI, NFS storage, and vSAN HCI Mesh can be used as supplemental storage for both the Management and VI WLDs. The following table shows the different storage options available:
Storage option | Mgmt WLD VxRail cluster | VI WLD VxRail cluster |
vSAN | Yes | Yes |
vSAN HCI Mesh | No | Supplemental Storage only |
FC Storage (VMFS) | Supplemental Storage only | Yes |
iSCSI Storage | Supplemental Storage only | Supplemental Storage only |
NFS Storage | Supplemental Storage only | Supplemental Storage only |

Note: In a consolidated architecture, a second or additional VxRail cluster in the Management WLD would have the same support as a VI WLD VxRail cluster.
