That sounds like my IBM ServeRaid 7.  I don't know much about the 8, do you know what the adaptec equivalent is?  I think mine is the 2410SA, and that uses the aacraid module.

Yeah,  unfortunately no. I think it is one of the few that isn't, from
Adaptec (my luck!). It's module name is: adpahci ; I haven't found this
anywhere except as Suse and RHEL rpms.

If you have heard of it though, do let me know. It's the Adaptec
HostRAID (IBM ServeRAID-8e) embedded in the motherboard.

From what I've read it's fakeraid, but at least it must deliver some
resources which would have been nice... Plus there's a sweet IBM
application which lets you manage and monitor the RAID (if it can find
the controller via the OS).
