Option
Controller Mode
•
When set to RAID: Expose RAW mode, all RAID functions of the controller are enabled.
Attached drives without Microsemi Adaptec metadata are surfaced to the host operating
system as RAW Pass Through devices (similar to JBODs on legacy Adaptec controllers).
•
When set to RAID: Hide RAW mode, all RAID functions of the controller are enabled, but
RAW devices are not exposed to the operating system.
•
When set to HBA Mode, attached drives are surfaced as RAW devices. The intent of this
mode is to allow the RAID controller to act and be used as an HBA. Changing into HBA
mode is allowed only if there are no drives with Microsemi Adaptec metadata attached
to the controller, including hot spare drives (see
Uninitializing Disk DrivesARCuninitializing
disk drivesdisk drivesuninitializinguninitializing disk drivesHBA mode
on page 61 for more
information). Uninitialized drives are compatible with any HBA and can be exchanged
with drives on the motherboard's SATA interface.
•
When set to Auto Volume Mode, attached drives without Microsemi Adaptec metadata,
but with an OS partition, are surfaced to the host operating system as RAW devices,
where the RAID layer of the controller firmware is bypassed when the host issues com-
mands to the device. Attached drives without Microsemi Adaptec meta-data and without
OS partitions, are automatically configured as Simple Volumes (single drives with Microse-
mi Adaptec meta-data). In Auto Volume Mode, you can create up to a maximum of 128
Simple Volumes; no other RAID types are supported. Auto Volume Mode enables DRAM
caching on rotating media to help reduce latency and accelerate performance.
•
When set to Simple Volume mode, you can create Simple Volumes only (up to a maximum
of 128 volumes); no other RAID types are supported.
Note: Before you can change into Auto Volume mode or Simple Vol-
ume mode, you must delete existing RAID arrays, maxCache Devices,
and hot spares drives (if any).
Default is RAID: Expose RAW mode.
Sets the maximum connection speed for SAS devices to 6 Gb/s or 12 Gb/s. Default is taken
from firmware.

Power Management Settings
Note: Default settings are shown in bold type.
Description
Option
When enabled, switches the system to low power state, based on the specified settings.
Power Management Settings
The time zone of the place in which the system is located. Time specific power management
settings are implemented based on the set time zone. By default, it is set to 00:00.
Time Zone
The valid range for the time zone settings is -12:00 to +12:00.
The time from which the system should operate in the full power mode, irrespective of other
power management settings, daily. By default it is set to 00:00.
Stay Awake Start
The valid range is 00:00 to 23:59.
The time until which the system should operate in the full power mode, irrespective of other
power management settings, daily. By default it is set to 00:00.
Stay Awake End
The valid range is 00:00 to 23:59.
The number of internal drives to be spun up at wakeup. By default it is set to 0. In the default
setting, all the internal drives will spin up.
Spin Up Limit (Internal)
The number of external drives to be spun up at wakeup. By default it is set to 0. In the default
setting, all the external drives will spin up.
