Table 16 P-VOL S-VOL Ports performance metrics
DescriptionUnitPerformance metrics
Port name.numberPort
Slot number.stringSlot
Communication mode configured for
the port, can be a MCU or RCU. MCU
stringMode
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.
Type of the port, can be Fibre, Ficon,
Escon, or FCoE (applicable only for
P9000 disk arrays).
stringType
Average I/O rate of the last
measurement interval.
IO/sCurIO
Minimal I/O rate of the last 60
seconds.
IO/sMinIO
Maximum I/O rate of the last 60
seconds.
IO/sMaxIO
Average I/O rate of the last 60
seconds.
IO/sAvgIO
Calculate average I/O size (=avg KB
/ avgIO).
KB/IOKB/IO
Average throughput of the last
measurement interval.
KB/sCurKB
Minimal throughput of the last 60
seconds.
KB/sMinKB
Maximum throughput of the last 60
seconds.
KB/sMaxKB
Average throughput of the last 60
seconds.
KB/sAvgKB
CA Journal Metrics
The CA Journal metrics includes the configuration data of P-VOLs and S-VOLs that belong to a
selected CTG. In addition, it includes performance metrics for the following components:
• LDEVs configured as P-VOLs or S-VOLs
• RAID groups to which the P-VOLs or S-VOLs belong
• CLPRs configured to manage cache for the P-VOLs or S-VOLs
• Journal group associated with the P-VOLs or S-VOLs
• LDEVs configured as journal volumes
• RAID groups to which the journal volumes belong
