Re: [Xen-users] Basic Xen Question

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).
