configured with different network interfaces (and therefore different IP
addresses) for data and replication traffic (see Network on page 366).
Generally, OST traffic is routed to the data network segment. However,
the OST Automatic Image Replication (AIR) and Concurrent Optimized
Duplication features use the replication network segment to transmit
data to the target system. (Optimized duplication can optionally use the
replication channel.) When a data IP address is mapped to a replication
IP address, OST traffic that is sent to one of the IP addresses is routed to
the other IP address as necessary.
Note: You must add target IP mapping information if you are
performing optimized duplication on a segmented network
and replication is not configured between the source DXi and
target DXi.
Note: Quantum does not recommend mapping multiple data IP
addresses to a single replication IP address. If you have mapped
multiple data IP addresses and the routing is not working, try
removing the additional data IP addresses, and map only a
single data IP address.
To access the Target IP Mapping page, on the OST page, click the
Target IP Mapping tab (see Figure 190 ).
