This topic describes the data configuration requirements inherent to Microsoft Exchange 2000 and 2003.
There can be between one and four storage groups in an Exchange server.
A storage group contains from one to five databases.
For Exchange 2003 only, there can be a fifth storage group called the Recovery Storage Group. SnapManager does not support backing up or restoring to this special storage group.
Note
The presence of a Recovery Storage Group can interfere with SnapManager's ability to perform a restore. For more information, see Exchange Recovery Storage Group incompatibility with SnapManager Restore.
An Exchange Server cluster has one or more Exchange virtual servers. In an active/active 2-node cluster, the maximum number of clustered storage groups is four for the entire clustered system because four is the maximum number of storage groups that can run on a single cluster node. An active/passive Exchange Server cluster can have more than two cluster nodes. The maximum number of Exchange virtual servers in an active/passive cluster is one less than the number of nodes in the cluster. An active/passive Exchange cluster can have more than four storage groups because only one Exchange virtual server runs on a cluster node at any given time.
