Change/increase the WSFC Parameter "QuorumArbitrationTimeMax" to 60.A DRS anti-affinity rule is required to ensure VMs, nodes of a WSFC, run on separate hosts.Clustered VMDKs must be attached to a virtual SCSI controller with bus sharing set to “physical.”.VMDKs must be Eager Zeroed Thick (EZT) Provisioned.But please check with the vendor regarding the support for Shared VMDK before using their plugin (MPP). Storage devices can be claimed by NMP or any other third-party (non-VMware) plugins (MPPs).Only supported with arrays using Fibre Channel (FC) for connectivity.Your array must support ATS, SCSI-3 PR type Write Exclusive-All Registrant (WEAR).Allowing you to migrate off your RDMs to VMFS and regain much of the virtualization benefits lost with RDMs.Ĭlustered/Shared VMDKs on VMFS6 Prerequisites With supported HW, you may now enable support for clustered virtual disks (VMDK) on a specific datastore. This is yet another move to reduce the requirement of RDMs for clustered systems.

What does this mean? You now have the ability to deploy a Windows Server Failover Cluster (WSFC), using shared disks, on VMFS. In vSphere 7, VMware added support for SCSI-3 Persistent Reservations (SCSI-3 PR) at the virtual disk (VMDK) level.

To enable and access NVMe over FC storage, install an FC adapter supporting NVMe in your ESXi host. This transport requires an FC infrastructure that supports NVMe. This technology maps NVMe onto the FC protocol enabling the transfer of data and commands between a host computer and a target storage device. ESXi emulates NVMeoF targets as SCSI targets internally and presents them as active/active SCSI targets or implicit SCSI ALUA targets. This enables ESXi hosts to discover, and use the presented NVMe namespaces. With NVMeoF, targets are presented as namespaces, which is equivalent to SCSI LUNs, to a host in Active/Active or Asymmetrical Access modes. For external connectivity, NVMe over Fibre Channel and NVMe over RDMA (RoCE v2) are supported. In vSphere 7, VMware added support for shared NVMe storage using NVMeoF. There are some requirements for external connectivity to maintain the performance benefits of NVMe as typical connectivity is not fast enough. Connectivity can be either IP or FC based. So how can you take advantage of NVMe devices in an external array? The industry has been advancing external connectivity options using NVMe over Fabrics (NVMeoF). Typically, NVMe devices are local using the PCIe bus. Industries, such as Artificial Intelligence, Machine Learning, and IT, continue to advance, and the need for increased performance continues to grow. NVMe continues to become more and more popular because of its low latency and high throughput.
