Distributing volumes evenly on DS8000 systems

DS8000® storage systems have two rank groups, 0 and 1, each managed by a single server. In addition, each DS8000 extent pool is based on one rank group.

Accordingly, it is recommended to spread volumes evenly across the DS8000 systems. Spreading the volumes equally on the extent pools of rank groups 0 and 1 balances the workload across the DS8000 system.
