4-6 Running the System Configuration Utility If your SMART-2 Array Controllers have 4-MB Array Accelerator boards, each installed SMART-2 Array Controller will consume 32-MB of physical memory space. If your SMART-2 Array Controllers have 16-MB Array Accelerator boards, each installed SMART-2 Array Controller consumes 128-MB of physical memory space. The amount of consumed address space may be reduced by modifying the PCI Memory Overlay Setting or changing the switch setting on the Array Accelerator board. a. Modifying the PCI Memory Overlay Setting: t No Overlay: Select this to not use the overlaying feature. t Overlay 32 MB: Select this if your controller has a 4-MB Array Accelerator board to reduce the amount of consumed physical memory to 32 MB, regardless of the number of SMART-2 Array Controllers installed. t Overlay 128 MB: Select this if your controller has a 16-MB Array Accelerator board to reduce the amount of consumed physical memory to 128 MB, regardless of the number of SMART-2 Array Controllers installed. b. Changing the Switch on the Array Accelerator Board t If your SMART-2DH Array Controller has a 16-MB Array Accelerator board, the amount of memory consumed per controller can be reduced to 32 MB by changing the switch setting on the Array Accelerator from 16 MB to 4 MB, as shown in Figure 4.1. This change works for all operating systems.
