Serial Attached SCSI RAID Controllers Installation and User's Guide
Description
When enabled, removable media devices, such as CD drives, are supported. (This
setting is not available on all RAID controller models.)
When enabled, the alarm sounds. Default is enabled.
Note: When the alarm is turned off (disabled), it will
remain off 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 High.
Note: This setting applies to new tasks. It does not affect
currently running tasks.
When set to Activity and Fault, the drive activity LEDs blink to indicate I/O activity
(randomly depending on I/O load) and fault (steady 1Hz). When set to Fault Only,
the drive activity LEDs blink to indicate fault state only. For Series 6/6E controllers,
default is Fault Only.
When set to Default, controller automatically sets the backplane mode to IBPI. To
set the backplane mode explicitly, select IBPI, SGPIO, or Disabled. Default is IBPI.
Note: With the default IBPI setting, the firmware sends
a SGPIO "Backplane_TYPE" signal if it recognizes that a
SGPIO Backplane is connected. If any connected SGPIO
backplane does not support the "Backplane_TYPE" signal,
or it does not support the IBPI protocol, you can manually
set the Backplane Mode to "SGPIO".
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.
When set to Big Block Bypass, DRAM write cache is bypassed based on I/O write
size; performance criteria is optimized for serving Web pages, file serving, and data
retrieval. When set to User Defined, you are prompted to use the OS tools to set
individual parameters (contact Adaptec support for more information). Default is
Dynamic.
When set to RAID Mode, all RAID functions of the controller are enabled. When set
to Auto Volume Mode, RAID functions of the controller are enabled. Attached drives
without Adaptec meta-data, but with an OS partition, are surfaced to the host
operating system as Pass Through devices, where the RAID layer of the controller
firmware is bypassed when the host issues commands to the device. Attached drives
without Adaptec meta-data and without OS partitions, are automatically configured
as Simple Volumes. When set to HBA Mode, attached drives are surfaced as Pass
Through devices. Changing into HBA mode is allowed only if there are no drives with
Adaptec meta-data attached to the controller (see
74 for more information). Default is RAID Mode.
Description
When enabled, switches the system to low power state, based on the specified
settings.
