Switching priority of an PFC group

All the host bus adapters (HBAs) in one PFC group must be of the same priority. Prioritized WWNs
and non-prioritized WWNs cannot be mixed in one PFC group.

You can use an PFC group to switch priority of multiple HBAs from prioritized to non-prioritized,
or vice versa.

Setting an upper-limit value to HBAs in an PFC group

If all the host bus adapters in an PFC group are non-prioritized WWNs, you can set an upper limit
value to HBA performance (i.e., I/O rate or transfer rate). You can assign one upper limit value
for one PFC group.

For example, suppose that the upper limit value 100 IOPS is assigned to an PFC group consisting
of four host bus adapters. If the sum of the I/O rate of the four HBAs reaches 100 IOPS, Performance
Control controls the system so that the sum of the I/O rates will not exceed 100 IOPS.
