HP 3PAR Application Software Suite for Microsoft Exchange - Manual (Page 19)

Connectivity
•
Both the servers, the backup server and the mailbox/Exchange server, must be connected to
the same HP 3PAR StoreServ 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 StoreServ
Storage Systems within the same site, the backup server must connect to two HP 3PAR StoreServ
Storage Systems with separate Fibre Channel or iSCSI connections. The HP 3PAR StoreServ
Storage Systems also need to be in the same Active Directory domain unless you have registered
multiple Active Directory domains.
