Improving RAID performance

[Christopher Trown <ctrown uoregon edu>]

     I've looked for some information, but nothing I've found helps much.

     I have an IBM xSeries 335 with two RAID 1 arrays, both U320.  One 
is the on-board LSI 1030 logic chipset, while the other is on an Adaptec 
2120S RAID controller.  The system was updated yesterday.  Redhat has 
finally included the latest aacraid driver!  Yay!

     I ran Bonnie++ to get an idea which was fastest.  The LSI array, 
which contains the system, is quite a bit faster, according to bonnie.

     Can anybody point me in the right direction to improving the 
Adaptec array's performance?  I tried getting into the Adaptec config 
BIOS, but no joy.  Cntrl-A displays a message stating it will go to the 
config utility, but the system goes right to Grub, then boots.  Bleah...

     Thank You.

Chris...
