In this case, the FCP PPRC ports share the adapter with FCP host ports. In general, sharing
the adapter bandwidth between PPRC and the host workload might lead to performance
issues especially during the PPRC full-copy operations. To avoid any possible interference
between PPRC and host workloads, you must use dedicated HAs for PPRC (or zGM data
mover) connections. For availability reasons, we advise that you spread the PPRC connection
across at least two HAs. The drawback of isolating the PPRC connections is that, with ...
