HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

IMPORTANT:
• At the Front-end main category level, the Maximum Port IO/s – Frontend and the Maximum Port
MB/s – Frontend metrics provide the respective maximum I/Os and MB/s of data throughput of
all the ports in the selected XP or the P9000 disk array. These values are the maximum of the last
collection interval. For example, if the port I/O collection interval is set to two minutes, the Max-
imum Port IO will be calculated as the maximum value over the two minute collection interval.
• When you plot the performance data points for a port ID, the associated port type is also displayed
in the legend for the selected port ID (example: (53046, CL2A (Fibre (Target)), Total).

Cache navigation path
The Cache main category comprises of individual CLPR partitions for the selected XP or P9000 disk
array (Cache > Individual CLPRs). The following image is an example for an XP disk array and shows
the CLPRs under the XP disk array Cache.
IMPORTANT:
CLPRs do not exist in an XP1024 Disk Array. So, the Cache related metrics are not displayed in the
Choose Metrics when you select a disk array of type XP1024.
