5-23 Controller Settings Screen In this screen (Figure 5-18), select the operating system and set the Rebuild Priority, Expand Priority, and Accelerator Ratio. Rebuild and expand priority selections have no impact on an "idle" system but will impact performance on a "busy" system. The Rebuild Priority affects the amount of time the controller spends rebuilding data after a failed drive has been replaced. Select High if rebuilding data should take precedence over handling requests from the operating system. Select Low if the controller should rebuild data only when it is idle. The Expand Priority affects when the controller moves data after you have chosen to expand the capacity of an array. Select High if expanding the array capacity should take precedence over handling requests from the operating system. Select Low if the controller should expand the array capacity only when it is idle. The Accelerator Ratio determines the amount of memory allocated to the read and write caches. Some applications may perform better with a larger write cache and others may perform better with a larger read cache. NOTE: This feature works with both 4-MB and 16-MB Array Accelerator boards. Use the Controller Settings Screen to select the Operating System, set the Rebuild Priority, Expand Priority, and Accelerator Ratio.
