RebuildPriority, ExpandPriority

These options have three possible values: Low, Medium, and High.

SSPState

There are two settings for this option: Enable and Disable. If you do not specify a value for the
SSP State, the existing setting remains the same.
NOTE: The SSPState option is valid only for controllers that enable SSP on a controller basis,
such as the MSA1000 or the Smart Array Cluster Storage controllers. RA4x00 controllers support
SSP that is enabled on a logical drive basis, and use the LogicalDriveSSPState option
instead.
If you enable SSP, you must also specify an adapter for one or more logical drives by using the
SSPAdaptersWithAccess option

SurfaceScanDelay

Enter a number between 1 and 30 to specify the duration of the surface scan delay in seconds.

Video performance options

To optimize the controller performance for video, set values for the following options as indicated:
DPOEnable = No
ElevatorSortEnable = Yes
IRPEnable = No
In addition, do the following:
Set the MNPDelay to any integer value from 1 to 60 (units are minutes). If you want to disable
this option, set a value of zero instead.
Set the QueueDepth to any integer value from 2 to 32, or to Auto.
