28-year REFORECASTS (1982-2009)

*pgb, flx, ipv and ocn for first 8 months of forecast ; **flx only for the rest of forecast

GRAND TOTAL = 3651 Tapes (2.55 PB)

Typical calculation

6 hourly 1.0 x 1.0 Flx for first 8 months: = 9 x 4 x 31 x 8 = 8.928 GB

6 hourly 1.0 x 1.0 Flx for next 6 months: = 9 x 4 x 31 x 6 = 6.696 GB

Total per run = 15.6 GB

Total for 7900 runs = 123.2 TB

Tapes (@ 0.7 TB/tape) = 176 Tapes
