6-44 Installing the Operating System Drivers 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. BASEDEV=CPQARRAY.ADD /PERF:[memory blocks] [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 Example: BASEDEV=CPQARRAY.ADD /PERF:6 Writer: Pamela King Project: SMART-2DH Array Controller Reference Guide Comments: 295469-002 File Name: G-CH06.DOC Last Saved On: 2/27/98 12:01 PM COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
