Replication Deployment Strategies; Active To Passive Example - HP StorageWorks D2D - Backup Systems User Manual

6. Click Update.
7. Now you can make the target library visible from other hosts. For iSCSI devices, log on to the
target library using the ISCSI Initiator. For FC devices, configure the FC fabric to make the host
visible. Target visibility persists even if the power fails or if the replication mapping is removed.
NOTE:
To remove target visibility, simply reset the Port to None. You will lose the iSCSI Initiator Node Name
and must reenter it to reinstate target visibility.

Replication deployment strategies

There are many deployment strategies; the following three are perhaps the most typical:
• Active to Passive
• Active to Active
• Many to One

Active to Passive example

In the following example there are two offices, each with an HP D2D Backup System. The HP D2D
Backup System in Office A is being used by the host server for backup and restore and the libraries
that have been configured on it are being replicated to matching libraries on the HP D2D Backup
System in Office B. A replication license is required only for the HP D2D Backup System in Office B.
That license covers all Replication-Target libraries on Appliance B.
