QoS Performance Reports
Table 55 (page 114) describes the metric shown for QoS Performance.
Table 55 QoS Performance Metric
Description Metric
Total (read + write) operations per sec Total IOPS
Delay in IO per sec IO Delay
IO Rejection per sec IO Rejection
Total (read + write) bandwidth in KBytes/s Total Bandwidth KBytes/sec
Bandwidth delay per sec Bandwidth Delay
Bandwidth rejection per sec Bandwidth Rejection
Average read service time in millisec Read Svct ms
Average write service time in millisec Write Svct ms
Average total (read + write) service time in millisec Total Svct ms
Wait read time at sample time Read Wait Time ms
Wait write time at sample time Write Wait Time ms
Average total (read + write) wait time at sample time Total Wait Time ms
Average size of read operations in KBytes Read IOSz KBytes
Average size of write operations in KBytes Write IOSz KBytes
Average size of read and write operations in KBytes Total IOSz KBytes
Queue length at the sample time.
NOTE: Unlike the other metric above, the queue length is an instantaneous measure
at the sample time, not an average over the sample interval.
Due to the way that RCFC ports process data, the Queue Length may not be a valid
measure.

Adaptive Optimization Reports
Table 56 (page 114) describes the metric shown for Adaptive Optimization Reports.
Table 56 Adaptive Optimization Report metric
Description Metric
