750 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
As shown in Figure A-4 on page 751, the Performance monitoring pane is divided into the 
following sections that provide utilization views for the following resources:
/SM590000CPU Utilization: The CPU utilization graph shows the current percentage of CPU usage 
and peaks in utilization. It can also display compression CPU usage for systems with 
compressed volumes.
/SM590000Volumes: Shows four metrics on the overall volume utilization graphics:
–R e a d
–W r i t e
– Read latency
– Write latency
/SM590000Interfaces: The Interfaces graph displays data points for FC, iSCSI, serial-attached SCSI 
(SAS), and IP Remote Copy interfaces. You can use this information to help determine 
connectivity issues that might affect performance:
– Fibre Channel
– iSCSI
– SAS
– IP Remote Copy
/SM590000MDisks: Also shows four metrics on the overall MDisks graphics:
–R e a d
–W r i t e
– Read latency
– Write latency
You can use these metrics to help determine the overall performance health of the volumes 
and MDisks on your system. Consistent unexpected results can indicate errors in 
configuration, system faults, or connectivity issues.
The system’s performance is also always visible in the bottom of the IBM Spectrum Virtualize 
window, as shown in Figure A-4 on page 751.
Note: The indicated values in the graphics are averaged on a 1 second based sample.
