whether the average sequential I/Os on each RAID group is
within or beyond the set threshold limit.
If the average sequential I/Os on a RAID group exceeds the
defined threshold limit, the
status icon appears.
The RG nonseq frontend reads (IOPS) threshold value indicates
the average non-sequential backend read tracks that you define
RG NonSeq Reads (IOPS)
an individual RAID group can manage over the threshold
duration. HP XP P9000 Performance Advisor uses this value to
verify whether the average non-sequential I/Os on each RAID
group is within or beyond the set threshold limit.
If the average non-sequential I/Os on a RAID group exceeds
the defined threshold limit, the
status icon appears.
The RG writes (IOPS) threshold value indicates the average
sequential backend write tracks that you define an individual
RG Writes (IOPS)
RAID group can manage over the threshold duration. HP XP
P9000 Performance Advisor uses this value to compare whether
the average writes (I/Os) on each RAID group is within or
beyond the set threshold limit.
If the average writes (I/Os) on a RAID group exceeds the defined
threshold limit, the
status icon appears.
The RG utilization threshold value indicates the average overall
RAID group utilization that you define for an individual RAID
RG Util (%)
group over the threshold duration. HP XP P9000 Performance
Advisor uses this value to verify whether the average overall
RAID group utilization of each RAID group is within or beyond
the set threshold limit.
The default threshold value is 50%.
If the utilization of one RAID group exceeds the defined
threshold, the
status icon appears.
The DKA Util (%) threshold value indicates the average overall
utilization of the MPs that can be utilized on an installed DKA
DKA Util (%)
over the threshold duration. HP XP P9000 Performance Advisor
uses this value to verify whether the average overall utilization
of each installed DKA is within or beyond the set threshold.
The default threshold value is 70%.
If the utilization of one exceeds the defined threshold limit, the
status icon appears.
NOTE:
The DKA Util (%) metric is applicable for the DKA MPs
only on the XP disk arrays.
MP Blade
If any of the MP blades usage exceeds the defined threshold limit during the specified threshold duration for an MP blade metric,
the
status icon appears in the MP Blade category in the XP/P9000 Array Health section. For example, if the usage of an MP
blade for the MP Blade Util (%) metric exceeds the defined threshold even once, the
status icon appears.
The MP Blade Util (%) threshold value indicates the average
overall utilization of the MPs that can be utilized on an installed
MP Blade Util (%)
MP blade over the threshold duration. HP XP P9000 Performance
Advisor uses this value to verify whether the average overall
utilization of each installed MP blade is within or beyond the
set threshold limit.
The default threshold value is 70%.
If the average utilization of one MP blade exceeds the defined
threshold limit, the
status icon appears.
