Statistics 

The storage administrator can monitor important statistics that define the 

level of system performance through the various management utilities. 
These statistics include Input and Output operations per second (IOPS) 
and bandwidth. 

5.2.1

 

Viewing IO/Second Summary 

 

Via Web Interface 

 

Click on the “Fibre Channel” graphic or the “Management 
Control Processor
” graphic 

 

Click on the “Statistics” tab 

 

Click the radio button next to “IOps” 

 

The graphing tool provides the option to view read, write, and total 
IOPS, as well as a running average of each of these statistics. To 

decode the colors on the graphical display, view the legend below 
the check boxes.
