I have a customer in London with a rather large IBM tape library.
Recently we were discussing an upgrade to new TS1140 drives and it shocked me how much additional capacity they would achieve and just how much they would have in total.
This is the actual diagram for the customer’s library (and is a clue)
I don’t for one minute think it’s the largest out there but it’s certainly not small and it’s run by one of the Worlds largest banks. A German Bank actually who have major operations around the Globe, with similar devices, but this library is one of three they operated in London.
I have provided you with a few clues above and below. See if you can guess how much data this library backs up & what its total capacity actually could be.
