How Arcserve RHA Enhanced Cluster Support Works

With the new Arcserve RHA plug-in for Microsoft Failover Cluster (MSFC) 2008, you can copy data between cluster nodes. There are three node roles:

• Source Node -- This is the node in the cluster currently communicating with the disk resource you wish to protect.
• Destination Node -- This is the node where you wish to copy data.
• Inactive Node -- This is the node in a cluster that is not communicating with the disk resource at a given point in time.

To copy data between cluster nodes, first create a new resource, an RHA disk to store data replicated from the source node. You can manage the new disk resource with the MMC snap-in, if you wish to change properties or monitor replication status. The Arcserve RHA Control Service (which should be installed on a separate server) is used to apply licenses. MSFC manages failover within the cluster while Arcserve RHA replicates the disk resource.
