Before you use a remote verification server, ensure that you establish the Windows host requirements, LUN requirements, and verification server designation.
Remote verification uses the same mechanisms as local verification, except that the verification occurs on a different host than the one that initiated the backup operation. This is why you need SnapDrive and SnapManager installed on your remote verification server, in addition to FC or iSCSI connectivity to the storage system.
If you use a remote verification server to verify the databases in multiple databases in a single job, you need an additional LUN.
You can designate your verification server from the production Exchange server.
