If you ever get a chance to poke around a large corporate data center -- see if you can check out a SL8500 or one of the TS3500 units.. They're the big things

If you ever get a chance to poke around a large corporate data center -- see if you can check out a SL8500 or one of the TS3500 units.. They're the big things with all kinds of flying robotic arms and crap-loads of storage. Just don't try and walk inside one while the robots are moving. For reference -- an LTO5 Tape holds about 3TB of data. (and has decent compression -- so that could go much higher)
