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).
