To Cluster or Not to Cluster? That is the Question.
Posted on 2014-07-17
Some background...I just received two new servers and a SAN. The servers are running VMware and are setup as two nodes in a clustered environment. While I got some crash-course training for VMware, I am a fresh fish to this game. I am setting up a new domain infustructure using all VMs running Windows Server 2012. We are a small shop that operates from 8-5 so if there is some down time for maintenance after hours or the weekend it is not a big deal.
I am in the process of getting setting up a Server 2012 File Server, and Exchange 2013 Server and a SQL 2014 Server. In your opinion, would you you create clusters for the File Server, Exchange Server and SQL Server? To do so, I would need to purchase an additional license for SQL and Exchange.
If my logic is correct, the clustered environment of these servers would protect me against an software OS failure. I already have vSphere HA so if one of my ESXi hosts goes down then the VMs would be transfered to another ESXi host. Therefore, the Windows clusters don't provide me any advantage if a hardware failure takes place.
So once again, would you run these Windows Servers in a cluster or just as a single VM?
I appreciate all your feeback!
