disk arrays
This chapter discusses the following topics:

• “Configuring dashboard threshold settings” on page 122
• “Viewing dashboard” on page 128
Introduction
P9000 Performance Advisor provides a dashboard, where you can view the overall usage status of
the XP and the P9000 disk arrays. The overall usage status is based on the usage of individual
components. Table 6 on page 119 lists the categories for an XP and a P9000 disk array and the
components that are grouped in each category:

IMPORTANT:
Since, the CHIP/CHA and the ACP/DKA MPs are moved to the MP blades in the P9000 disk arrays,
their MP utilization metrics are not applicable for the P9000 disk arrays.
The usage data of components is retrieved for a threshold duration of 6 hours, 12 hours, or 24 hours,
and for those metrics whose threshold limits are set in the categories (see Table 6 on page 119 on the
Threshold Settings screen. Based on their usage, the appropriate status icons are displayed in the
respective categories in the XP/P9000 Array Health section of the Dashboard screen. For example,
if the usage of even one RAID group crosses the set threshold limit at least once in the last 12 hours,
the status icon appears in the XP/P9000 Array Health section in the Backend category and indicates
critical use of one or more RAID groups in that category.
If you have not set the threshold limit for even one metric in a category, the status icon appears in
that category in the XP/P9000 Array Health section.
