Bandwidth of Tape

As part of the ongoing Stage 2 upgrade at VLSCI we received an extra 1,000 LTO5 tapes, each rated at 1.5TB uncompressed, for an additional raw, uncompressed, storage of 1.5PB. Now we typically get around 2X compression so that’s about 3PB usable. It took our team about 3 hours to uncrate, unpack, transfer and load the 1,000 tapes, effectively shifting 1.5PB of tape in an hour. That’s about 139GB/s or if you are a network person 1.1Tb/s. Not bad! 🙂
