• Session Balancing
Copy sessions are scheduled evenly to each Controlling CM for a copy source RAID
group (a RAID group to which the copy source volume belongs).
• Destination RAID Group Balancing
Only one copy session can be performed for each copy destination RAID group. This
method prevents unequal loading on a specific RAID group. This may improve the
copy performance when the copy source storage system and the copy destination
storage system are connected by direct connection and the copy destination RAID
group is configured by Nearline disks.
• Copy performance is not improved by selecting "Destination RAID Group Balancing" in the following conditions:
- When the type of the copy destination volume is not "Standard"
- When the copy destination volume "Standard" and concatenated
• Specify the same copy schedule mode for copy source and copy destination storage systems. If different modes
are specified, the copy performance may not improve as expected.
Description Select a bandwidth setting mode.
