Disk space for input datasets (data on DBS):

  • phiSym disk space per day = 25 kB/ev (ev size) * 1kHz (L1_ZeroBias rate) * 12 h (fill duration, assuming 1 fill per day) * 3600 s = 1 TB/day

  • phiSym for 3 weeks = 21 TB

  • piZero disk space per day = 5 kB/ev * 7 kHz * 12 h * 3600s = 1.4 TB/day -> 30 TB for 3 weeks

Disk space on EOS for outputs:

  • same as input phiSym for Eflow (21 TB)

  • ECALELF rerecoes 10 TB
