Does anyone know how  I can find out if an ibm serveraid 8k sas storage

I am trying to decide if I should get the serveraid controller or go get
a 3ware controller.

Tom,

The ServeRAID 8k s a real hardware raid controller, is has 256 MB of
cache I think and a battery backup. So in this case there is no need
for a 3ware controller. On the IBM website you can also find a
commandline tool (called arcconf) that allows you monitor and
configure the controller inside Linux.

Is there a place where this kind of thing is documented? I looked through Google
for about 3 hrs yesterday and I could not find anything definitive.

Thank You, for the info.

Regards,
