Wsus cluster aware updating
To use or configure Cluster-Aware Updating you have to install the RSAT for Clustering via GUI or via Windows Power Shell: CAU can be scheduled to updates clusters without any manual action.First choose the cluster and enable the self-updating feature on the cluster Specify the self-updating schedule Specify the updating options Save the scheduled self-updating process After you have configured the self-updating process you can still modify it.In Windows Server 2012 Microsoft introduced Cluster-Aware Updating or short CAU.Cluster-Aware Updating allows you to update your cluster nodes via automated workflow.Any reasons to not deploy patches on a regular basis should have been done away with the presence of patching solutions from Microsoft and many others. It’s messy because, by definition, a cluster hosts mission critical services such as virtual machines.
If you run some Clusters with 16 nodes you know how much time was needed for manually updating the cluster nodes.
With Windows Server 2012 the new maximum number of nodes in a cluster is 64, so CAU will save administrators a lot of time and will keep your clusters up to date.

Launch the Cluster-Aware Updating Wizard and then run Apply Updates To This Cluster.
The status of the update job will be visible under Log Of Updates In Progress.
