Note: Make sure the operating system driver supports power management.
Note: Default settings are shown in bold type.
Physical Drives Display
During POST
When enabled, connected disk drives are displayed during system Power
On Self Test (POST). Displaying the disk drives adds a few seconds to
the overall POST time. Default is disabled.
DVD/CD-ROM Boot

When enabled, the system can be booted from a bootable CD. (This
setting is not available on all RAID controller models.)
Removable Media
Devices Boot Support
When enabled, removable media devices, such as CD drives, are

Note—When the alarm is turned off (disabled), it will automatically turn
back on after a reboot.

Sets the default priority for background tasks on the controller (such as
logical drive creation) to High, Medium, or Low. Default is Medium.
Note—This setting applies to new tasks. It does not affect currently
running tasks.
LED Indication Mode When set to Activity/Fault, the drive LEDs blink to indicate I/O activity
(randomly depending on I/O load) and fault (steady 1Hz). When set to
Fault Only, the drive LEDs blink to indicate fault state only. Default is
Activity/Fault.
Backplane Mode When set to Auto, controller automatically detects backplane signal
type: I2C or SGPIO. To set the backplane mode explicitly select SGPIO,
I2C, or Disabled. Default is Auto.
Selectable Performance
Mode
When set to Dynamic, performance criteria adjusts automatically based
on controller usage, RAID level, and disk drive type. When set to OLTP/
Db, performance criteria is optimized for transaction-oriented
applications, such as data entry and retrieval. Default is Dynamic.
