Final plot for Run 14

5977 TB ~ 5.84 PBytes - we exceed the projected (adjusted) raw by near a factor of x2.

Initial plan

The STAR computing resource plan, based on the BUR and event estimates for the projected species, predicted we would gather and save roughly 2.8 PBytes of storage. The plan accounted for a fudge factor, taking into account a historical divergence to our plans and ended with a total estimate of 3.00 PBytes of storage. The derived MuDST size was projected to reach an unprecedented 1.92 PBytes.

Projections

April snapshot

The current STAR data taking is showed (graphically) below (as up to April 1^st 2014).

The next graph represents a projection of the data for up to an additional - in summary, we seem to be on a path to use 2.1 PBytes of storage / month and with at least a good 2 months left, this would indicate a projection to 4.0-4.5 PBytes (a minimum of a 50% excess from the initial plan).
