    • 100 GB quotas in staged roll out, plan detailed in tickets above

    • Tooling to generate quota information
      • Calculate current quotas from sponsorship information (Clayton)

        • Clayton suggests adding up all sponsored quotes and giving them either that, or the minimum 100GB quota (whichever is bigger).
        • RT1298614
    • Good to proceed?
      • Nick: Nov 1st deadline should be enough time for users to bring their disk usage < 100GB
      • Anthony: Want to enable quotas for all users under 100GB for the start of term (in preparation of new accounts)
      • Anthony: The lack of sponsorship quota information should not block the 100GB quota deployment
