Connectivity
•
Both the backup server and the mailbox servers must be connected to the same HP 3PAR
Storage System.
•
To manage a DAG-enabled configuration from a single backup server for DAG nodes that
connect to two HP 3PAR Storage Systems within the same site, the backup server must connect
to two HP 3PAR Storage Systems with separate Fibre Channel or iSCSI connections. The HP
3PAR Storage Systems also need to be in the same Active Directory domain unless you have
registered multiple Active Directory domains.
