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:
❏
No Overlay: Select this to not use the overlaying feature.
❏
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.
❏
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
❏
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.
