Disk I/O workload multiplier
Meaning
The relative change in disk I/O utilization desired when sizing an existing workload to better
simulate a new workload in a scenario. Disk I/O can be made smaller, the same, or larger than
that available for the workload chosen as the baseline value.
Default
The default value is 1.0 (no change).
Where you might use this multiplier
• When creating a workload or editing its attributes
Example
To increase the disk I/O available to a new workload by 10% of that available to the chosen
baseline workload, enter a multiplier of 1.1.
Determining estimated utilization assumptions for a workload
Use these fields to set parameters for the workload's utilization of resources.
When you use an existing workload profile (Copy Profile), you leverage data that already exists
for a workload to examine alternatives. When you use a static workload profile (Static Profile),
you create a profile based on independent values.

Disk I/O Workload Multiplier
A positive or negative integer used to move an
occurrence of peak activity to an alternate desired
time.
For example, suppose that peak activity in the
profile data set occurred at 12:00 PM, but the
desired peak time to be simulated is 9:00 AM.
Setting the Offset Hours to –3 will move the peak
time in the simulation from 12:00 PM to 9:00 AM.
Default: 0
