This graph shows the aggregate transfer rate to the storage systems as a function of time of day. The red line is the peak bandwidth observed within each one minute interval. The green line is the average over ten minute intervals.
This graph shows the number of transfers to the storage systems that are initiated each minute. Most of these complete in just a few seconds, so only a few transfers are still in progress at the end of the minute. The transfers still in progress at the end of the minute are shown in green. The transfers in progress at the end of the minute are concurrent, so the green line is similar to the values shown in the graph above on concurrency.
