At our IT Camp in Minneapolis a few weeks ago, Kris asked me a valid question.

“How does a Hyper-V Server (not the full windows install) do clustering if you can’t install the cluster role?”

Kris’s question is a good one, because we had just been discussing how limited Hyper-v Server is in terms of what it can do, while at the same time supporting all of the same virtualization features and scale that a full Windows Server 2012 R2 machine with the Hyper-V Role installed does; including the ability to be joined to a Windows Failover Cluster.

In fact, during the discussion of what roles are supported on Hyper-V Server, I showed this screenshot:

Roles

So if you thought Windows Failover Clustering was a role, you’d be scratching your head at this one.

“Ah.. so what’s the catch?”

No catch.  Windows Failover Clustering is not a role.  It’s a feature!

Features

It’s actually in the list of features rather than roles.  It’s not enabled by default, and the Create Cluster wizard actually enables it when needed.

Pretty slick.
