Enabling Virtual SAN automatically configures and registers a storage provider for each host in the Virtual SAN cluster.

Virtual SAN storage providers are built-in software components that communicate datastore capabilities to vCenter Server. A storage capability is typically represented by a key-value pair, where the key is a specific property offered by the datastore. The value is a number or range that the datastore can provide for a provisioned object, such as a virtual machine home namespace object or a virtual disk. You can also use tags to create user-defined storage capabilities and reference them when defining a storage policy for a virtual machine. For information about how to apply and use tags with datastores, see the vSphere Storage documentation.

The Virtual SAN storage providers report a set of underlying storage capabilities to vCenter Server. They also communicate with the Virtual SAN layer to report the storage requirements of the virtual machines. For more information about storage providers, see the vSphere Storage documentation.

Virtual SAN registers a separate storage provider for each host in the Virtual SAN cluster, using the following URL:


where host_ip is the actual IP of the host.

Verify that the storage providers are registered.


  1. Browse to vCenter Server in the vSphere Web Client navigator.
  2. Click the Configure tab, and click Storage Providers.


The storage providers for Virtual SAN appear on the list. Each host has a storage provider, but only one storage provider is active. Storage providers that belong to other hosts are in standby. If the host that currently has the active storage provider fails, the storage provider for another host becomes active.
Note: You cannot manually unregister storage providers used by Virtual SAN. If you need to remove or unregister the Virtual SAN storage providers, remove corresponding hosts from the Virtual SAN cluster and then add the hosts back. Make sure at least one storage provider is active.
