P-VOL S-VOL Port performance metrics
Table 16 describes the performance metrics of ports configured as the master and receiver ports for
the P-VOLs and S-VOLs.

Port name.numberPort
Slot number.stringSlot
Communication mode configured for the port, can be a MCU or
RCU. MCU refers to the Master port that is configured to send I/Os
to the RCU (Receiver port) residing on the remote data center disk
array. RCU is configured to only receive I/Os from the MCU residing
on the remote data center disk array. The performance data shown
is for the MCUs and RCUs that belong to the disk array you selected.
stringMode
Type of the port, can be Fibre, Ficon, Escon, or FCoE (applicable
only for P9000 disk arrays).
