When using external volumes of AMS2000 series storage system with a copying program
product, the copy operation needs to be distributed to two or more RAID groups.
There is an upper bound to the number of pairs that can be used for initial copy or
resynchronization. Therefore, the copy operation may focus on a specific RAID group according
to the order of the copy operation when the copy operation is performed to two or more
external volumes. The drive of the AMS2000 series storage system may become a bottleneck,
causing insufficient performance, when the copy operation focuses on a specific RAID group.
