BIOS CONFIGURATION

3.7.5.8 Volume Data Read Ahead

The volume read data ahead parameter species the controller

rmware 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 satises the performance

requirements for a typical volume. The "Disabled" value implies

no read ahead. The most efcient 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.
