We present a velocity-dispersion-based mass calibration of the South Pole Telescope Sunyaev-Zel'dovich effect survey (SPT-SZ) galaxy cluster sample. Using a homogeneously selected sample of 100 cluster candidates from 720 deg 2 of the survey along with 63 velocity dispersion ( v ) and 16 X-ray Y X measurements of sample clusters, we simultaneously calibrate the mass-observable relation and constrain cosmological parameters. Our method accounts for cluster selection, cosmological sensitivity, and uncertainties in the mass calibrators. The calibrations using v and Y X are consistent at the 0.6 level, with the v calibration preferring 16% higher masses. We use the full SPT CL data set (SZ clusters+ v +Y X ) to measure 8 ( m /0.27) 0.3 = 0.809 0.036 within a flat CDM model. The SPT cluster abundance is lower than preferred by either the WMAP9 or Planck+WMAP9 polarization (WP) data, but assuming that the sum of the neutrino masses is m = 0.06 eV, we find the data sets to be consistent at the 1.0 level for WMAP9 and 1.5 for Planck+WP. Allowing for larger m further reconciles the results. When we combine the SPT CL and Planck+WP data sets with information from baryon acoustic oscillations and
