Adaptec RAID Configuration Utility
■ Controller Configuration Options:
■ Drives Write Cache (Default: Drive's Default)—When
Enabled, write cache is enabled, providing maximum
drive performance. When Disabled, no write cache is used
on the drive. By default, the drive’s setting is used.
Caution: When Enabled, there is a slight possibility
(less than with controller cache) of data loss or
corruption during a power failure.
■ Runtime BIOS (Default: Enabled)—When Enabled, the
Adaptec 2810SA controller BIOS allows the controller to
act as a bootable device. Disabling the BIOS allows
another suitable controller to act as the boot device.
■ Automatic Failover (Default: Enabled)—When Enabled,
the controller automatically rebuilds an array when the
failed drive is replaced. When disabled, the array must be
rebuilt manually.
■ Array Background Consistency Check (Default:
Disabled)—When Enabled, the controller continuously
performs a verification on a redundant array to data
integrity. In the case of RAID 1 or 10, consistency checks
assure that the data between like blocks match. In the
case of a RAID 5, consistency checks assure that data in
the stripe and the calculated parity for the stripe match.
Consistency checking processes reduce performance. For
a RAID 5, the performance reduction is significant.

BBS Support
(Default:
Enabled
)—When
Enabled
in systems
that support BBS, controller is presented as a bootable
device in the host system's BIOS for boot device selection.
■ Array-based BBS Support (Default: Disabled)—When
Enabled in systems that support BBS, the controller
presents attached bootable devices up to the host
system's BIOS for boot device selection. This is relevant
for logical arrays.
■ Physical Drives Display during POST (Default:
Disabled)—When Enabled, attached physical devices are
