128TB tape cartridges key to kilometer-size telescope

128TBtape cartridges key to kilometer-size telescope. Computerworld. Lucas Mearian. December 6, 2012.
In one day, the telescope's dishes will generate 10 times the network traffic produced at the same time on the global Internet. They will feed about 10 petabits of data (1 billion gigabits) per second into a central computer that will have the processing power of about 100 million of today's PCs.  The project plans to generate 1 million GB of data per day and store 300 to 1,500 petabytes (1.5 exabytes) of data per year. IBM is responsible for the data storage and they plan to use tape. "The tape will be used as a deep archive." Construction is expected to start in 2016 and take four years. The exascale supercomputer is expected to be completed by 2024.
