Updating cabinet

As failover clusters are all about high availability of services hosted on the cluster, one would almost never patch all cluster nodes at the same time.

So patching a failover cluster usually meant a fair number of manual steps, scripting/tools, and juggling administrator’s attention across a number of clusters to successly update them all during a short monthly maintenance window.

CAU allows you to update clustered servers with little or no loss in availability during the update process.You can then have CAU “connect” to any failover cluster using appropriate administration credentials, and update the cluster on demand For an overview of the scenario, check out the CAU Scenario Overview.In previous releases of Windows, the server updating tools (e.g.WSUS) did not factor in the fact that a group of servers could be members of a highly-available cluster.Addressing this was always the #1 ask for Windows Server 2012, during all the discusssions we had with customers in early days of release planning.
