DescriptionOption
Adaptec Series 7, Series 8, and Series 6E/6T Controllers:
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 rmware 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" sig-
nal, 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 con-
troller usage, RAID level, and disk drive type. When set to OLTP/Db, performance
Selectable Performance Mode
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
IO write size; performance criteria is optimized for serving Web pages, le serving,
and data retrieval. When set to User Dened, you are prompted to use the OS
tools to set individual parameters (contact Adaptec support for more information).
Default is Dynamic.
Adaptec Series 7 and Adaptec Series 8 Controllers Only:
Controller Mode
When set to RAID: Expose RAW mode, all RAID functions of the
controller are enabled. Attached drives without Adaptec meta-data
are surfaced to the host operating system as RAW Pass Through de-
vices (similar to JBODs on legacy Adaptec controllers).
When set to RAID: Hide RAW mode, all RAID functions of the con-
troller 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 Adaptec meta-data attached to the controller, includ-
ing hot spare drives (see Uninitializing Disk Drives on page 87 for
more information). Uninitialized drives are compatible with any HBA
and can be exchanged with drives on the motherboard's SATA inter-
face.
When set to Auto Volume Mode, attached drives without Adaptec
meta-data, but with an OS partition, are surfaced to the host operat-
ing system as RAW devices, where the RAID layer of the controller
rmware is bypassed when the host issues commands to the device.
Attached drives without Adaptec meta-data and without OS parti-
tions, are automatically congured as Simple Volumes (single drives
with Adaptec meta-data). In Auto Volume Mode, you can create up
to a maximum of 128 Simple Volumes; no other RAID types are sup-
ported. 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 Volume mode, you must delete existing RAID arrays,
maxCache Devices, and hot spares drives (if any).
Default is RAID: Expose RAW mode.
