Storage quality-of-service in cloud-based scientific environments: a standardization approach

Abstract: Abstract. When preparing the Data Management Plan for larger scientific endeavors, PIs have to balance between the most appropriate qualities of storage space along the line of the planned data life-cycle, its price and the available funding. Storage properties can be the media type, implicitly determining access latency and durability of stored data, the number and locality of replicas, as well as available access protocols or authentication mechanisms. Negotiations between the scientific community and the re… Show more

“…Thus it is desirable to have specific, fixed data placement strategies that provide particular storage and performance characteristics. These different strategies are called QoS (Quality of Service) Classes [3]. By allowing scientists to choose and modify with which QoS Class they would like their data stored, a storage system gives scientists the ability to achieve the optimal storage strategy within the available storage capacity.…”
