time of restarting the server. Updates are performed in batches at the scheduled time by using iDRAC. The batch size is
determined when the update is happening. Refresh the inventory to check if all the updates are applied. The entire update

– Agent-free updates — is out of band update with immediate server restart.
– Cluster-Aware Updating (CAU) — automates the update process by leveraging Windows CAU feature on cluster update
groups to maintain server's availability. Updates on servers happen through cluster update coordinator which is present on
the same system where Integration Gateway (IG) is installed and not through iDRAC. The updates are not staged and are
applied immediately. Using CAU you can minimize any disruption or server downtime allowing continuous availability of the
workload. Hence, there is no impact to the service provided by the cluster group. For more information on CAU, see Cluster-
Aware Updating Overview section at
