Storage system throughput

Function

Total throughput is the sum of I/Os per second. The read throughput is I/Os to the disk per second when the file read processing is performed. The write throughput is I/Os to the disk per second when the file write processing is performed.

Throughput in the following modes can be displayed:

Sequential access mode
Random access mode
Total value in the above-mentioned modes

Storing period

Sample Interval can be specified from 1 to 15 minutes.

Selection of monitoring objects

Select the desired monitoring objects in the Performance Objects field.

Note: Volumes that do not accept I/O from the host, such as pool-VOLs, are not monitored. The total number of accesses is displayed. The same value is output to all LUNs mapped to the LDEV.
