VCF 5.1 supports the ability to deploy a VI WLD with external storage as principal storage with no VxRail managed vSAN. This feature allows support for a VxRail dynamic node cluster with three nodes or more to be added to a VI WLD. VCF 5.1 SDDC Manager allows 2-node clusters when using vLCM and connecting to external storage as primary. These nodes contain no internal storage disks normally required for vSAN.
The following requirements must be met before deploying a VxRail dynamic node cluster with FC storage as principal storage.
Supported storage arrays:
Supported FC HBAs:
Storage configuration required:
If multiple datastores are discovered during VxRail Day 1 workflow, the largest one will be selected as the primary datastore for the VxRail systems.
If multiple datastores are discovered of the same size, a random one will be selected during VxRail Day 1 workflow.
