2.1 What is 3PAR GeoCluster for Windows?
3PAR GeoCluster for Windows is an add-on to Microsoft Cluster Server. It manages the
hosting of Microsoft Cluster Server nodes on 3PAR InServ storage arrays in synergy with
3PAR Remote Copy, allowing the nodes to be located in geographically remote sites and
replicated in real-time. It ensures continuity of service in most cases of site failure and an
enhanced Recovery Time Objective in case continuity of service has been disrupted.
