IBM Flex System V7000 Storage Node Introduction and Implementation Guide

The error 1625 in the above example was caused because of one of our Control Enclosure 
controllers had been temporarily removed from the system.

Figure 5-29 shows that few more errors remain as unresolved. These should be fixed as the 
one we just resolved in the example above.

The IBM Flex System V7000 Storage Node has a Performance menu which gives a first 
impression of how the system is performing. The performance chart is split into four sections:

��

CPU Utilization - subdivided into:

– CPU time used for the system
– CPU time used to handle compression

��

Interfaces - subdivided into:

– FC - Fibre Channel traffic towards hosts
– iSCSI - shows iSCSI traffic towards hosts
– SAS - traffic towards the disk backend

��

Volumes - traffic towards hosts that has mapped volumes - subdivided into:

– Reads in MegaByte per second (MBps)
– Writes in MegaByte per second (MBps)
– Red latency in milli seconds (ms)
– Write latency in milli seconds (ms)

��

MDisks - traffic towards the disk backend - subdivided into:

– Reads in MegaByte per second (MBps)
