    We want only to use one LUN (or two) due to the fact that we are using this
     device for as a backup device on the backup server.
    We want as much flexibility as possible at the filesystem level, and hence
    we want one
    filesystem.

    Data is primarily written to the backup disk and then copied to tape.
    This way we are able to do most restores from disk, which is faster.
    We are using Legato Networker 7.1.

    The storage system we are using is a Nexsan Ataboy II, a cheap IDE based
    RAID system,
    we are only using one scsi card in the server towards the storage system.

    To keep this a pretty high Performing, but very low cost solution.
