This picture looks like, e.g.: Actually I mentioned the switch because as far as I know you can configure it in such a way that the host will never see disks that it's not intended for. That should isolate the hosts from each other even if FC id's go in and out? It is analogous to VLAN on ethernet. We will probably look into that again soon. We need [HW] RAID on a handful of machines and I would rather spend the money on a couple of good storage arrays instead of buying one for each machine. NFS is out for our environment. Would you happen to have a host-independent (stand-alone) FC RAID controller that you can recommend? Thanks!
