Command Line Switches - Compaq Smart Array 221 User Manual

Remove all IDE or ESDI (ST-506) disk drivers from CONFIG.SYS if you are
using a Smart Array 221 Controller drive. Make sure that the
"BASEDEV=IBM1S506.ADD" line is deleted.

Command Line Switches

You may want to modify the standard behavior of the Compaq ADD driver.
Several command line switches are available for this purpose. The syntax of the
command line switches is:
1. /PERF:[memory blocks]
This command line switch is a non-standard switch implemented for the
CPQARRAY.ADD. It should be used to modify the performance
characteristics of the driver when using a Smart Array 221 Controller.
Under heavy disk utilization this command switch allows greater
performance based on the number associated with the [memory blocks]
parameter. The larger the [memory blocks] parameter the better the
performance under heavy disk utilization. Be aware that when you
increase this parameter, the CPQARRAY.ADD driver uses more
memory.
BASEDEV=CPQARRAY.ADD /PERF:[memory blocks]
Where [memory blocks] = A number in the range of 3 to 9 indicating the
amount of memory blocks allocated per Smart Array 221 Controller in
the system. The driver runs at a default value of 5. To determine the
amount of memory being used you can use this formula:
Number of Smart Array 221 Controllers * [memory blocks] * 64-kb
Example:
BASEDEV=CPQARRAY.ADD /PERF:6
