Your Virtual Volumes environment must include storage providers, also called VASA providers. Typically, third-party vendors develop storage providers through the VMware APIs for Storage Awareness (VASA). Storage providers facilitate communication between vSphere and the storage side. You must register the storage provider in vCenter Server to be able to work with Virtual Volumes.

After registration, the Virtual Volumes provider communicates with vCenter Server and reports characteristics of underlying storage. The characteristics appear in the VM Storage Policies interface and can be used to create a VM storage policy compatible with the virtual datastore. After you apply this storage policy to a virtual machine, the policy is pushed to Virtual Volumes storage. The policy enforces optimal placement of the virtual machine within Virtual Volumes storage and guarantees that storage can satisfy virtual machine requirements.


Verify that the storage provider component is installed on the storage side and obtain its credentials from your storage administrator. For information, contact your vendor.


  1. Browse to vCenter Server in the vSphere Web Client navigator.
  2. Click the Manage tab, and click Storage Providers.
  3. Click the Register a new storage provider icon.
  4. (Optional) To direct vCenter Server to the storage provider certificate, select the Use storage provider certificate option and specify the certificate's location.

    If you do not select this option, a thumbprint of the certificate is displayed. You can check the thumbprint and approve it.

  5. Click OK to complete the registration.


vCenter Server discovers and registers the Virtual Volumes storage provider.
