QoS Performance Reports
Table 55 (page 114) describes the metric shown for QoS Performance.
Table 55 QoS Performance Metric

Total (read + write) operations per secTotal IOPS
Delay in IO per secIO Delay
IO Rejection per secIO Rejection
Total (read + write) bandwidth in KBytes/sTotal Bandwidth KBytes/sec

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.
