Cluster workloads
You should carefully review Microsoft documentation and resources for properly
configuring your cluster before implementing Storage Mirroring Recover on a cluster.
The Microsoft TechNet articles Failover Clusters and Installing and Upgrading Cluster
Nodes are two resources you can start with. There are many other resources available
on the Microsoft TechNet web site.
l Double-Take Source Connection resource—In a clustered environment, MSCS
handles failover between nodes of the cluster. By using the Double-Take Source
Connection resource, you can further protect your data by replicating the cluster
data to a target. The Double-Take Source Connection resource automatically
starts mirroring and replication after a group changes nodes on the source. In the
event the cluster fails, your cluster data will be available on the target.
l Target cluster—If your target is also a cluster, connect the Double-Take Source
Connection resource to a virtual IP address on the target.
l Auto-reconnect—Storage Mirroring Recover mirroring should be controlled by the
Double-Take Source Connection resource. Therefore, you must disable the default
auto-reconnect process for each node in the cluster. This option is available
through the Server Properties Setup tab. Disable the option Automatically
Reconnect During Source Initialization.
l Storage Mirroring Recover disk queue—Ensure that the disk queue is not on a
Physical Disk resource. See the installation optimizations and Queuing data for
more details on the disk queue.
l Exchange or SQL protection—If your source is a cluster running Microsoft
Exchange or SQL, use the Storage Mirroring Recover Application Manager,
instead of trying to use the Double-Take Source Connection resource. The
Application Manager does support clusters for Exchange and SQL.
l Cluster service account—For Windows 2003 clusters, use the same cluster
service account on source and target clusters.
