Windows Server VM Cluster Network

Jump to solution

Happy New Year!

We are starting to use VMs for a few MS SQL always on availability groups/clusters. The clusters/server/SQL are setup and working, but I want to create an "internal" network for the cluster traffic only. I know how to do this in the physical world, and I am sure things can be setup the same in the virtual world. My question is about creating a cluster only network in vCenter so that the cluster traffic, from these two virtual SQL servers, never leaves the vSwitch. I have 16 hosts in a cluster running ESXi v6.0U3, the vCenter is the same version and I am using a virtual distributed switch.

Any suggestions are appreciated.

You would just set it up like any other port group. Assuming the SQL servers sit on different ESXi hosts the traffic will still need to pass through 1 or more physical switches though.

If the SQL servers sit on the same ESXi host then traffic would never leave that host
