If you enable SSP, you must also specify an adapter for one or more logical drives by using the
SSPAdaptersWithAccess option ("
" on page
). 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
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.
•
In Reconfigure mode, ACU can either create a new array or reconfigure an existing array. In this case,
the value that you specify can identify an existing array, or it can correspond to the next available array
letter or pair of letters in the existing configuration.
Drive
You can use this option to add a drive to an existing array (to expand an array) or to build a new array. If
you are expanding an array, each drive that you add must have a capacity no less than that of the smallest
drive already in the array. The added drives and the existing drives in the array must all be the same type (for
example, SAS or SATA).
If the value of the ClearConfigurationWithDataLoss (on page
) option is Yes, you can use the
Drive option to remove drives from an array. However, the ClearConfigurationWithDataLoss
option is now deprecated.
