HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

The applicable metrics are displayed in the Available Metrics Choose Metric Category list. Select the

metrics at the component type or the individual component levels, or both to view the related

performance graphs in the Chart Work Area. For a description of these metrics, see “Metric Category,

metrics, and descriptions” on page 439.

The following table provides the default set of metric categories that are displayed in the Available

Metrics Choose Metric Category list for the XP and the P9000 disk arrays. The Yes and No under For

the XP disk arrays and For the P9000 disk arrays columns indicate whether the particular default

metric is applicable for that XP or P9000 disk array.

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).
