Dell Unity supports access to vVol datastores over block and file protocols. Fibre Channel or iSCSI can be used for block access and NFSv3 is used for file access.
Note: vVols with NFSv4 is not supported on Dell Unity systems.
For Fibre Channel, ensure that the ESXi host is zoned to the FC ports on both SPs for multipathing purposes. Alternatively, the ESXi host can be directly connected to both SPs. When the connection and zoning are complete, the Fibre Channel ports log in and the process is complete when the World Wide Names (WWNs) are displayed in the Initiator Paths page.
If iSCSI is used, iSCSI interfaces must be created on both SPs. In the vSphere Web Client, add one of the iSCSI interfaces that was created as a dynamic discovery target. The iSCSI interface on the other SP is discovered automatically. Afterwards, run a rescan of the storage adapter and confirm the initiator IQNs are displayed in the Initiator Paths page.
File protocol access requires the creation of a NAS server, which contains file protocol configuration information such as networking, protocols, and DNS settings. It is highly advisable to create at least one vVols-enabled NAS server on each SP for load balancing and high availability purposes. Using vVols with IP multi-tenancy is not supported, and you cannot enable the vVol protocol endpoint on a NAS server that has a tenant association. To use vVols, you must use a NAS server that does not have a tenant assigned. In order to access vVol datastores, an NFS and vVols-enabled NAS server must be created, as shown in Figure 9.
