IRPEnable
This option is not supported.
LicenseKey, DeleteLicenseKey
These options are not supported.
MNPDelay
This option is not supported.
NoBatteryWriteCache
With this option, the controller can enable write cache when no battery is present or when the battery fails.
Values are Enable or Disable. The default is Disable.
Some controllers do not support this option.
ParallellSurfaceScanCount
The ParallelSurfaceScanCount command specifies the number of parallel surface scans which can be active
at any time. The minimum and maximum values are controller and firmware release dependent. This feature
is not supported by all controllers.
N - number of scans
Power modes
IMPORTANT: A reboot may be required after switching power modes in order to optimize savings
and performance.
IMPORTANT: When the power mode is set to Balanced, future controller configuration changes
may require a reboot for optimal performance.
This option modifies the controller power mode.

A value of minpower sets static settings to the lowest possible value and dynamically reduces power
based on the workload.

A value of balanced sets statistic settings based on the configuration and dynamically reduces power
based on the workload (recommended).

A value of maxperformance sets static settings to the highest possible value and does not dynamically
reduce power (default).
Example: PowerMode= [ MinPower | Balanced | MaxPerformance ]
QueueDepth
This option is not supported.
RapidParityInitialization
This option enables Rapid Parity Initialization. The RPI command is not supported on all controllers and is
dependent on firmware and hard disk support. Command options are Enable or Disable.
ReadCache, WriteCache
Enter a number between 0 and 100 to specify the percentage of cache that is to be allocated to drive reads
or writes. The default values for both options are controller firmware-dependent.
