Domain controller needed for Clustering?

  • I started on a new job and I noticed they're using 2 redundant domain controllers on the host. I asked them what it was used for and they told me it's for the SQL server clustering. Are Domain Controllers a requirement for Clustering?

  • The short answer is that a cluster does indeed need to reside in a domain. Are you saying that the domain controllers reside on the SQL Server boxes? The [reside] "on the host" is what is throwing me.

  • When I said host, I meant the hosting service, my apologies for not being clear.

    They have 2 domain controllers and 2 separate SQL server machines. Could you please explain the need for a domain for clustering, or point me to an explanation?

    Thanks!

  • Having a domain is at the heart of cluster installation. You need a domain for the virtual name, for instance. See the install documentation . The very first thing it requires is a domain account:
