Click the New device drop-down menu, select SCSI Controller, and click Add.

In the vSphere Client, select newly created virtual machine, right-click and select Edit Settings.WSFC on vVols supports HA, DRS and vMotion.This feature enables customers to move away from using Pass-through RDM (physical compatibility mode).N+1 cluster configuration, in which one ESXiВ host has virtual machines which are secondary nodes and one primary node is a physical box is not supported.Cluster-in-a-box (CIB) and a mixture of CAB and CIB is not supported.Only Cluster-across-box (CAB) is supported.The underlying transport protocol can be FC, ISCSI or FCOE.WSFC on vVols can work with any type of disk, вЂњThinвЂќ as well as вЂњThickвЂќ-provisioned disks.All hosts must be running ESXiВ 6.7 or above.

ESXiВ 6.7 supports vVols Storage for Windows Server 2008 SP2 and above releases.

The storage array must support SCSI persistent operations at the subsidiary LUN level.

ESXiВ 6.7 supports vVols storage with up to 5 node WSFC.

Be sure to use HW Version 13 or greater on your FCI VMs.

Follow the Guidelines for setting up WSFC on vSphere 6.xВ keeping a few vVols specific guidelines in mind: The process for setting up WSFC on vVols is pretty straight forward. Now, vVols support in ESXI 6.7 enables up to 5 WSFC cluster nodes to access the same shared vVol disk. Up until vSphere 6.7 there was onlyВ one scenario where you couldnвЂ™t use vVols for SQL Server, and that was shared storage between SQL Server instances. Today, RDMs are required to allow SCSI reservations to be passed directly to the quorum/witness device without being handled/interpreted by the VMkernel I/O stack. WSFC is one of the very last use cases for Physical Mode Raw Device Mappings (pRDMs). Other features of SCSI-3 include persistent reservations across reboots and supporting multi-pathing to disks.

This is called registration and reservation, which allows one node to eject another node.

By allowing multiple nodes access to an individual disk, this allows Microsoft WSFC to manage the locking along with the storage. SCSI reservations allow multiple nodes to access a shared disk at a storage level while restricting simultaneous access to that shared disk from other nodes to avoid data corruption. This is great news for customers still working with RDMs.В WSFC clustering solutions use SCSI-3 Persistent Reservations which enables access for multiple nodes to a device (vVol disk) and simultaneously blocks access for other nodes. One of the announcements in the vSphere 6.7 launch that caught my attention was vVols support for WSFCВ (Windows Server Failover Clustering) using SCSI-3 Persistent Reservations.
