Nutanix – Windows Failover Clustering

Acropolis base software 4.5 and 4.1.5 supports configuring Windows guest VMs as a failover cluster. This clustering type enables applications on a failed VM to fail over to and run on another guest VM on the same or different host. This release supports this feature on ESXi, Acropolis Hypervisor (AHV) and Hyper-V hosts with in-guest VM iSCSI and SCSI 3 Persistent Reservation. In the past you would have had to setup MS Availability Groups using a file server for quorom. Availability groups are great but getting people to switch adds additional constraints for setup and training. The other downside from field is that there are tons of people running SQL 2008 and availability groups don’t exist there.

You have the ability to create a Volume Group with multiple vDisks that get attached using iSCSI. If your using AHV the disk attachment to the VM can be automatic. On AHV, the Volume Group gets attached to a specific SCSI bus and can happen while the VM is running. The shared Volume Group can be shared among multiple machines.

Note: AHV is apart of the MS Server Virtualization Validation Program. Nutanix has certiied with Windows 2012 R2. When a vendor validates their virtualization solution with Windows Server 2012 R2, then Windows Server 2012, Windows Server 2008 R2, Windows Server 2008 and Windows Server 2003 SP2 and subsequent service packs are also supported.


  1. I am new to Nutanix and find this to be a very cool feature.
