Microsoft Cluster Technology

Cluster nodes share a disk

Only one node can ownthe disk at any time

At failover, disk ownershipis transferred

How GeoCluster Works

ReplicationReplication

GeoCluster nodes use separate disks,kept synchronized by real-time replication

Only the active nodeaccesses its disks

At failover, the newactive node resumes

with current,replicated data

Data is replicated toall passive nodes
