If for example you had a DL380 G4 with 6 U320 15K 72GB disks for use as a small exchange server.
RAID1 = OS
RAID1 = Databases
RAID1 = Logs
Can I do this with just the onboard 6i controller? What advantages would I get from purchasing a separate controller?
Solved! Go to Solution.

The DL380 G4 gives several options to duplex the back plane. You could duplex the backplane by using the two channels of the 6i or to get some performance gain you could throw in a PCI controller and duplex between the 6i and the PCI controller.
The duplex split is 2/4.

Duplex Channel 1
6i Controller
Disks 0,1 RAID1 for the OS
Duplex Channel 2
641 Controller
Disks 2,3 RAID1 for the databases
Disks 4,5 RAID1 for the transaction logs
Would I see a noticeable performance difference in doing this?
Would I see a noticeable performance difference if I used a more expensive card than the 641 controller? the 6402 for instance.
