ESXi Supports Round Robin Path Selection Policy (PSP_RR) for disk resources used by WSFC

ESXi supports PSP_RR for WSFC.

• ESXi supports PSP_RR for Windows Server 2012 and above releases. Windows Server 2008 SP2 and earlier are not supported.
• PSPs configured in mixed mode is supported. In a 2 node WSFC cluster in CAB configuration one ESXi host can be configured to use PSP_FIXED and the other ESXi host can use PSP_RR.
• All hosts must be running ESXi 6.0 or later.
• Mixed mode configurations of ESXi 6.0 or later with previous ESXi releases are not supported.
• If the number of paths to a storage device exceeds 5, WSFC cluster storage validation may fail if Round Robin path policy (PSP_RR) with iops =1 is used. In such cases, we recommend setting the number of iops to 5 or more when Round Robin path policy is used. This is not a VMware issue.
