Rolf,

How would your 3590 compare to an IBM Ultrium 3584? I'm currently
spec'ing a system(s) to run 10 LTO Ultrium tape drives in an
IBM 3584 which will eventually backup close to 30TB.
My experience in production is only with DLT7000. We found
that a Solaris (HAL7000 clone) with 3(ea) 296MHz CPU's and 3GB of RAM
could keep our tape drives streaming at 5-6MB/sec using Legato's NetWorker
software. We are currently transitioning to IBM's Tivoli. With LTO's
10-12MB/sec writing capability, I'm thinking 1 SCSI controller
per 2 tape drives, 2 controllers per CPU & 1G RAM per CPU as a
rough estimate.

Thank you for your help,

        Hallo Boe,
        I did this last year and decide to use a SUN E450 with two CPUs, 1 GB 
RAM,
        and as tape devices IBM 3590 (15MB/s speed), now total 8 drives 
connected via
        fiber channel.

        We save some 20 SAP systems full backup daily and a lot of UNIX/NT 
server,
        total backuped storage perhaps 1 TB uncompressed.

        Greetings,
