When configuring block Virtual Volume (vVol) datastores over Fibre Channel or iSCSI, protocol endpoint devices are presented to the vSphere hosts rather than disk devices. These protocol endpoint devices are used for tuning as described in section 3.3. Best practices regarding block vVol datastores mirror those of the standard block storage described previously in this paper.
When configuring file-based (NFS) vVol datastores in a Dell Technologies Unity environment, it is recommended to create at least two vVol-enabled NAS servers: one on SPA and the other on SPB. Additionally, committing two or more interfaces per SP can result in better performance, but this follows the same guidelines and limitations as NFS datastores described in Best Practices for Running VMware vSphere on Network-Attached Storage (NAS).
