Data Archive

DKRZ currently archives about 8 Petabytes (8.000 Terabytes) of new model data per year, resulting from the climate simulations on its supercomputer. For the near future, however, we expect a strong increase in the amount of data to be archived.
Tape Libraries

With the HLRE-II system "Blizzard", about 8 Petabytes of new simulation results had to be archived per year. Starting with the availability of the new HLRE-3 "Mistral" in summer 2015, we expect the yearly data growth to increase to up to 75 Petabytes per year.
