BIOS CONFIGURATION

3.7.5.8 Volume Data Read Ahead

The volume read data ahead parameter specifies the controller
firmware algorithms which process the read ahead data blocks
from the disk. The "Data Read Ahead" parameter is normal
by default. To modify the value, you must set it from the "
Raid System Function" using the 'Volume Data Read Ahead"
option. The default "Normal" option satisfies the performance
requirements for a typical volume. The "Disabled" value implies
no read ahead. The most efficient value for the controllers
depends on your application. The "Aggressive" value is optimal
for sequential access but it degrades random access.

3.7.5.9 Hdd Queue Depth Setting

This parameter is adjusted the queue depth capacity of NCQ
(SAS HDD) or Tagged Command Queuing (SAS HDD) which
transmits multiple commands to a single target without waiting
for the initial command to complete.
