Avg Read Latency
The average time that it took the Symmetrix to serve one read IO for this group.
Max Read Latency
The MAX of the average time that it took the Symmetrix to serve one read IO for this group.
Read Latency Std Dev
The Std Dev of average time that it took the Symmetrix to serve one read IO for this group.
Avg Write Latency
The average time that it took the Symmetrix to serve one write IO for this group.
Max Write Latency
The MAX of the average time that it took the Symmetrix to serve one write IO for this group.
Write Latency Std Dev
The Standard Deviation of average time that it took the Symmetrix to serve one write IO for this group.
