Command Line Switches

In certain situations you may want to modify the standard behavior of the
Compaq ADD driver. Several command line switches have been made
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-2DH Controller.
Under heavy disk utilization this command switch will allow 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 will use more
memory.
[memory blocks] A number in the range of 3 to 9 indicating the
amount of memory blocks allocated per SMART-2DH 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-2DH Controllers * [memory blocks] * 64kb
