Updating Dell Servers by Integrating SUU/DUP with Cluster-Aware Updating On Microsoft Windows Server 2012

This white paper is a guide for integrating Dell firmware and driver updates using the Dell Server Update Utility (SUU) or Dell Update Package (DUP), without impacting the cluster for Microsoft Windows Server 2012, using Microsoft Hotfix Plug-in feature of Cluster-Aware Updating.

Executive summary

This white paper describes the process of integrating Dell Server Update Utility (SUU) into a new Windows Server 2012 feature called Cluster-Aware Updating (CAU). Specifically, Dell Update Package (DUP)- based update process integration into Microsoft Hotfix plug-in feature in CAU will help you realize updating firmware and drivers with continuous availability of Dell server clusters running Microsoft® Windows Server® 2012. This process allows IT Administrators to maintain server uptime while keeping Dell servers updated using either the Dell Server Update Utility (SUU) or individual Dell Update Packages (DUPs).


IT Administrators face many challenges in updating the cluster. It requires multiple manual steps with associated planned failover and failback of clustered Roles, all during a short maintenance window of time. This process is highly error-prone and increases the risk of unplanned service outages. Cluster-Aware Updating (CAU) is a feature in Microsoft Windows Server 2012 that coordinates software updates on all servers in a failover cluster without impacting the service availability. This white paper explains how an IT Administrator can update Dell server firmware and driver using SUU or DUP by integrating Microsoft Hotfix plug-in, feature of Cluster-Aware Updating.
