vSAN clusters can share their datastores with other vSAN clusters. You can provision VMs running on the local cluster use storage space on the remote datastore.
Use the Datastore Sharing view to monitor and manage remote datastores mounted on the local vSAN cluster. Each client vSAN cluster can mount remote datastores from server vSAN clusters located within the same data center managed by the vCenter Server. Each compatible vSAN cluster also can act as a server, and allow other vSAN clusters to mount its local datastores.
Mounting a remote datastore with HCI Mesh is a cluster-wide configuration. You can mount a remote datastore to a vSAN cluster, which is then mounted to all hosts in the cluster.
When you provision a new virtual machine, you can select a remote datastore that is mounted to the client cluster. Assign any compatible storage policy configured for the datastore.
Monitor views for capacity, performance, health, and placement of virtual objects show the status of remote objects and datastores.
HCI Mesh vSAN has the following design considerations:
- Clusters must be managed by the same vCenter Server and be located within the same data center.
- Clusters must be running 7.0 Update 1 or later.
- Clusters must be enabled for vSAN.
- A vSAN cluster can serve its local datastore to up to five client vSAN clusters.
- A client cluster can mount up to five remote datastores from one or more vSAN server clusters.
- A single remote datastore can be mounted to up to 64 vSAN hosts, including hosts in the vSAN server cluster.
