HP 3PAR Application Software Suite for Microsoft Exchange - Manual (Page 18)

Connectivity
•
Both the backup server and the mailbox/Exchange servers must be connected to the same HP
3PAR Storage System.
•
To manage a DAG-enabled configuration (or a CCR enabled configuration for Exchange
2007) from a single backup server for DAG/CCR 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.
