You can create a storage policy for a virtual machine to specify which storage capabilities and characteristics are the best match for this virtual machine.
vSAN uses storage policies to allow specification of the characteristics of virtual machines, so you can define the policy on an individual disk level rather than at the volume level for vSAN.
You can identify the storage subsystem capabilities by using the VMware vSphere API for Storage Awareness (VASA) or by using a user-defined storage policy.
VMware vSphere API for Storage Awareness
With vSphere API for Storage Awareness, storage vendors can publish the capabilities of their storage to VMware vCenter Server, which can display these capabilities in its user interface.
User-defined storage policy
You define the storage policy using the VMware Storage Policy SDK, VMware vSphere PowerCLI, or vSphere Web Client.
You can assign a storage policy to a virtual machine and periodically check for compliance so that the virtual machine continues to run on storage with the correct performance and availability characteristics.
You can associate a virtual machine with a virtual machine storage policy when you create, clone, or migrate that virtual machine. If a virtual machine is associated with a storage policy, the vSphere Web Client shows the datastores that are compatible with the policy. You can select a datastore or datastore cluster. If you select a datastore that does not match the virtual machine storage policy, the vSphere Web Client shows that the virtual machine is using non-compliant storage. See Creating and Managing vSphere Storage Policies in the vSphere 6.5 documentation.
