1. Based on your requirement, select a record corresponding to a port, RAID group, or an MP
blade in the respective Frontend, Backend, or the MP Blade Statistics section.
2. Click Show Consumers.
The maximum X busiest consumers are displayed in the Components Information section. The
records are also sorted in the ascending or the descending order as specified on the Threshold

the LDEV data collected for the XP/XP7 disk array configurations
involves
64K or higher number of LDEVs, the response time to display the most and least X
busiest
LDEVs may be in the range of 1 to 5 minutes.
The following table displays the cu:ldev ID of the LDEVs associated with the selected RAID group
or the port for an XP disk array. In addition, the corresponding RAID group or the port usage
appears for the following set of metrics.
Description Metrics
The average latency for reads or writes on the LDEV during the
specified threshold duration. Avg Read/Write Response Time (ms)
The frontend I/Os on the LDEV during the specified threshold
duration. IOPS
The frontend throughput in MB/s read and written to the LDEV
during the specified threshold duration. Block IO MBPS
The average of the overall RAID group utilization of an individual
