5.6.1 Extended Example I/O Workload Analysis

This I/O workload analysis extended example details the
application of Profile and Trending Analysis to the I/O
workload data collected in the extended example introduced in
Section 3.3.3.1.

To illustrate the use of the reports, monthly data was
collected for the selector and block multiplexor channels on
the base channel group of a 9021-711 to study the growth of
the system's I/O workload.  Each channel is characterized by
average percent busy and the number of SIOs completed during
the month.

The following topics are addressed:

 1 - Problem Description
 2 - Control Parameters
 3 - Output Reports
