HP XP Performance Advisor Software - Manual (Page 41)

NOTE:
The mix CHIP shows only eight ports and four MPs though there are eight MPs on that board. The
remaining four behave as ACP MPs.
The XP24000 disk array has 8 ACP pairs, 32 CHIPs, and 4 MPs per port.
If configuration data is collected through the in band mode for array configured with external storage
volumes, the RAID group information of the external storage volume is displayed as Ext-RdGp. All
volumes of the external array group is considered as a single non-existing (virtual) group, is termed as the
External Raid Group and is denoted by Ext-RdGp. Performance data is collected for all the volumes.
All virtual volumes that are not associated with any pool, do not have RAID group information, and of
unknown type, are considered as a single non-existing (virtual) volume group. This single non-existing
(virtual) volume group is denoted as VVol-Grp in the RAID Grp column in the Grid Display screen and
Performance data is collected for all these volumes.
When configuration data is collection through the in band mode on any array, other than XP24000,
configured with snapshot volumes associated with snapshot pools, then all snapshot volumes and pools
are collectively displayed as Snap-Grp. Performance data is collected for all these volumes.
Utilization Summary
Click the General group box on the Array View screen to display the Utilization Summary for the array in
a separate browser window, as shown in the Utilization Summary .
Figure 15 Utilization Summary
Use the Utilization Summary to view a snapshot of array activity for cache usage, bus utilization, CHIP
processor utilization, and ACP processor utilization. The Utilization Summary view also lists the array’s
serial number, model, firmware version, and the data and time when data collection occurred. Click blue
text to view the Utilization Metric chart for that component.
