For an XP disk array, Min% indicates the minimum CPU util-
ization on PCB [%].
For a P9000 disk array, Min% indicates the minimum
processor utilization on an MP blade. In Figure 21 the Min%
indicates the utilization of MP3.
%Min%
For an XP disk array, Max% indicates the maximum CPU
utilization on PCB [%].
For a P9000 disk array, Max% indicates the maximum
processor utilization on an MP blade. In Figure 21 the Max%
indicates the utilization of MP0.
%Max%
For an XP disk array, Avg% indicates the average CPU util-
ization on PCB [%].
For a P9000 disk array, Avg% indicates the average
utilization of all MPs. In Figure 21 the Avg% indicates the
utilization of MP0, MP1, MP2, and MP3.
