Tandem Capacity Model (TCM) Manual

Figure 48 CPU Factors Screen
The leftmost column contains the names of the supported processor types in TCM. The first row
contains the RVUs. The table contains the conversion factors for different configurations of CPU
types and RVUs.
The rightmost column contains the IPU count for multi-core processors and this field is not applicable
for single core CPUs.
When the CPU configuration types differ, the model's planned CPU consumption is estimated from
the actual CPU consumption using these factors. A new CPU type or RVU can be added to the
blank fields in the table. You must be either a TCM administrator or a superuser to change the
values in this screen.
If the available fields are less than the number of new CPU types and RVUs to be added, you can
overwrite the factor, processor, and RVU names of some existing unused CPU type and RVU pair.
To restore the original table, select the Refresh Formulas command from the Update tab and then
select the CPU Conversion Factors screen.
Disk Factors Screen
This screen lists the disks for TCM, with their model numbers, rotational speeds, controllers, disk
read seek time and write seek time. Figure 49 (page 151) shows a sample Disk Factors screen.
