An administrator has deployed a three-host vSphere cluster with a small amount of VMFS storage and wants to add additional capacity from a vSAN ESA cluster located in the same vCenter Server. When the administrator selects the vSphere cluster and navigates to the Configure tab, the Datastore Management option is missing under the vSAN section. What prerequisite must be met before the administrator can mount the remote datastore?

Answer options

A: The vSphere cluster must be deployed to a different VCF Workload Domain.

B: vSAN must be enabled on the non-vSAN cluster to act as a compute cluster. Correct answer

C: The vSAN Storage cluster must have a minimum of 80% free space.

D: A fourth host must be commissioned for the vSphere cluster.

Correct Answer:

B. vSAN must be enabled on the non-vSAN cluster to act as a compute cluster.

Explanation

To mount a remote vSAN datastore using vSAN HCI Mesh (or Cross-Cluster Capacity Sharing), the client cluster (the cluster mounting the datastore) must be configured as a vSAN compute cluster. This requires vSAN to be enabled on the client cluster, even if it does not have any local storage devices contributing to a local vSAN datastore. Once vSAN is enabled on the compute-only cluster, the Datastore Management option becomes available, allowing the administrator to mount the remote vSAN datastore from the vSAN ESA cluster.

Why Incorrect

- A: vSAN HCI Mesh supports sharing datastores across different clusters within the same vCenter Server; they do not need to be in different VCF Workload Domains.
- C: There is no strict 80% free space prerequisite on the remote vSAN storage cluster to simply mount the datastore.
- D: A vSphere compute cluster can mount a remote vSAN datastore with as few as two or three hosts; a fourth host is not a prerequisite.
