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/XP7 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 Maximum 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 XP7 disk
array (Cache > Individual CLPRs). The following image is an example for an XP disk array and
