it is a cheap ide-based arena raid box that appears to the system as a scsi disc and has it's own risc processor, but you misunderstood. that is the fast system that doesn't cause any problems. the slow system is even much slower than some smaller systems we use for development with less powerful CPUs and cheap ide discs, no raid (forgot to add that in my first email).
