Check the zoning and the system status and make sure that the clusters can “see” each
other. Then you can create your partnership by selecting the appropriate remote storage
system (Figure 9-72), and defining the available bandwidth between both systems.

In our example we have built the relationship between FlexSystem_V7000 and ITSO_SVC1
The bandwidth you need to input here is used by the background copy process between the
clusters in the partnership. To set the background copy bandwidth optimally, make sure that
you consider all three resources (the primary storage, the inter-cluster link bandwidth, and the
auxiliary storage) to avoid overloading them and affecting the foreground I/O latency.
