Our largest ADSM server:

> Machine: RS/6000 J30 (192MB ram, ~50GB of SCSI RAID5 disk)
> TapeLibrary: STK 9710 library, 15 TB capacity
        Drives:  7 DLT 7000
> TotalData: ? changes hourly!
> DataPerDay: 15-20 GB (compressed)
> Clients:       ~20 UNIX & NT servers
                        ~250 Wintel desktops
        Network:        16MB token ring

        We use compression on all clients.
        Never have put any significant stress on the J30 or the 9710.
