When using vendor provider components, the vCenter Server can integrate with external storage, both block storage and NFS, so that you can gain a better insight into resources and obtain comprehensive and meaningful storage data.
The vendor provider is a software plug-in developed by a third party through the Storage APIs - Storage Awareness. The vendor provider component is typically installed on the storage array side and acts as a server in the vSphere environment. The vCenter Server uses vendor providers to retrieve information about storage topology, capabilities, and status.
For information about whether your storage supports the vendor provider plug-ins, contact your storage vendor.
If your storage supports vendor providers, use the Storage Providers menu option in the vSphere Client or the vSphere Web Client to register and manage each vendor provider component.
