This past year the Con­trols group within the Col­lider Ac­cel­er­a­tor De­part­ment at Brookhaven Na­tional Lab­o­ra­tory re­placed the Net­work At­tached Stor­age (NAS) sys­tem that is used to store soft­ware and data crit­i­cal to the op­er­a­tion of the ac­cel­er­a­tors. The NAS also serves as the ini­tial repos­i­tory for all logged data. This pur­chase was used as an op­por­tu­nity to cat­e­go­rize the data we store, and re­view and eval­u­ate our stor­age strate­gies. This was done in the con­text of an ex­ist­ing pol­icy that places no ex­plicit lim­its on the amount of data that users can log, no lim­its on the amount of time that the data is re­tained at its orig­i­nal res­o­lu­tion, and that re­quires all logged data be avail­able in real-time. This paper will de­scribe how the data was cat­e­go­rized, and the var­i­ous stor­age strate­gies used for each cat­e­gory.
