RebuildPriority, ExpandPriority This option has 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 unchanged. 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 ("LogicalDriveSSPState" on page 84) instead. If you enable SSP, you must also specify an adapter for one or more logical drives by using the SSPAdaptersWithAccess option ("SSPAdaptersWithAccess" on page 85). Otherwise, SSP is automatically disabled. 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: • 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. Array category The Array category has the following options: • Array (on page 81) • Drive (on page 82) • DriveType (on page 82) • OnlineSpare (on page 82) Array Enter a letter or pair of letters to identify the array that is to be created or reconfigured, and observe these additional limitations: • In Configure mode, ACU creates a new array. The value that you specify for the array option must be the next available letter or pair of letters in the sequence, according to the number of existing arrays on the controller.

RebuildPriority, ExpandPriority
This option has 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 unchanged.
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
("
LogicalDriveSSPState
" on page
84
) instead.
If you enable SSP, you must also specify an adapter for one or more logical drives by using the
SSPAdaptersWithAccess option ("
SSPAdaptersWithAccess
" on page
85
). Otherwise, SSP is automatically
disabled.
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:
•
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.
Array category
The Array category has the following options:
•
Array (on page
81
)
•
Drive (on page
82
)
•
DriveType (on page
82
)
•
OnlineSpare (on page
82
)
Array
Enter a letter or pair of letters to identify the array that is to be created or reconfigured, and observe these
additional limitations:
•
In Configure mode, ACU creates a new array. The value that you specify for the array option must
be the next available letter or pair of letters in the sequence, according to the number of existing
arrays on the controller. AA follows Z, and BA follows AZ.
