Tandem Capacity Model (TCM) Manual

Effective with SPR T6042H01^ABD and later, SAS disks are supported, with CLIM as the controller.
However, XP disks are partially supported.
If XP disks (subtype 52) are installed, then the DISKFACTOR directive must specify a SAS disk
model name and subtype 51. However, the controller, read seek, and write seek times can reflect
the actual values of the real disk types in the system.
The syntax follows:
DISKFACTOR m r c s readseek [writeseek]
where:
m
is the disk model number for which the default RPM, controller type will change. Acceptable
values for DISKFACTOR Model, Speed, Controller, Subtype and Seek Times are shown in
Table 5 (page 47).
r
is the RPM value of a disk, which is a measure of the speed of rotation. This value is a positive
number between 00000.01 and 99999.99.
c
is the disk controller type. Acceptable values are MFC, Ext, Snet, FCSA, and CLIM.
s
is the disk subtype, to be entered when an extra record of a new disk is required. The subtype
is not overridden for existing disk model numbers. This value is a positive number between 49
and 99.
readseek
is the read seek time of the disk in milliseconds. This value is a positive number between 01.00
to 09.99.
[writeseek]
is the write seek time of the disk in milliseconds. This is optional; if not specified, it will be
considered to be same as the readseek time. This value is a positive number between 01.00
to 09.99.
This entry also allows the user to add up to five new disk model numbers.
The default values of the rotational speed, controller type, subtype, read seek and write seek times
for various disk model numbers are:
