HP XP P9000 Performance Advisor Software - Manual (Page 209)

IMPORTANT:
•
The response time is calculated from the time the I/Os are received by the CHA port till the
time they are dispatched from the CHA port.
•
If the LDEV is a LUSE Master, the details of individual LDEVs are considered for the busiest
components and not the sum of all the individual LDEVs.
•
The Maximum Port IO is the maximum of the last collection time stamp. For example, if port
I/O collection interval is set to two minutes, the Maximum Port I/O will be calculated as the
maximum value over the two minute collection period.
•
The port type, such as Fibre or FCoE (applicable only for P9000 disk arrays) is also displayed
for the respective port ID.
