Compaq SmartArray seems slow

Compaq SmartArray seems slow

[Tom Peters]

My Compaq SmartArray 3200 under SuSE 9.2 seems pretty slow. Is there some 
voodoo in the BIOS of a Compaq machine that makes it work properly? I don't 
have a Compaq machine, just the SmartArray card cabled externally to a 
Proliant with everything disabled and unplugged except the power supply, 
case fans, and Compaq array cages.

The test results didn't change materially when I added another controller 
(the promise Ultra 100 ATA).

The docs say you can use both external connections if you don't use the 
inside ones, so I did that. I have a 5-drive hotswap cage cabled to one 
external connector, and a 3-drive hotswap cage cabled to the other.

The third group is the Compaq array controller.
