BIOS CONFIGURATION

3.7.5.9 Hdd Queue Depth Setting

This parameter is adjusted the queue depth capacity of NCQ

(SATA HDD) or Tagged Command Queuing (SAS) which trans-

mits multiple commands to a single target without waiting for

the initial command to complete.

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 Read Ahead parameter is normal by default.

To modify the value, you must set it from the command line

using the 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. Aggressive read ahead

is optimal for sequential access but it degrades random access.
