   * In the sliding tier, when you reach your soft limit, notify HPC admins and your quota will slide to the next strata (< 90/100G, < 225/250G, < 450/500G, < 700/750G). Once you reach the last strata, and you still need more disk space, you enter the custom tier.     * In the sliding tier, when you reach your soft limit, notify HPC admins and your quota will slide to the next strata (< 90/100G, < 225/250G, < 450/500G, < 700/750G).
