that greatly increase the MP usage rate. Adding the performance items
together does not equal the total estimated capacity of the MPs. Likewise,
this performance information is not appropriate to estimate the usage of
a particular resource.

* The kernel type is any one of the following types:

Open-Target, Open-Initiator, Open-External, MF-Target, MF-External, BackEnd, or System.
