摘要： A method for routing an incoming service request is described wherein the service request is routed to a selected storage tier based on that selected storage tier having a predicted value indicating a state having greater utility as compared with the predicted value of the state associated with at least one other storage tier within the storage system. A computer system comprising a multi-tier storage system is described, the multi-tier storage system having a routing algorithm configured to adaptively tune functions which map variables describing the state of each storage tier of the storage system into the average latency experienced by incoming service requests associated with the storage tier.

摘要： A method and apparatus for managing data is described which includes determining the current state of a storage tier of a plurality of storage tiers within a storage system. Further, a prediction is made, using a prediction architecture comprising at least one predetermined variable, of the utilities of future expected states for at least two of a plurality of storage tiers involved with a data operation, wherein a future expected state of a corresponding storage tier is based on conditions expected to occur following the completion of the data operation. Finally, the data operation is performed if the predicted utility of the future expected state associated with the at least two of a plurality of storage tiers is more beneficial than the utility of the current state.

摘要： In one embodiment, a method and apparatus for ring optimization for data sieving writes is disclosed. The method includes dividing a file range to be written to via a data sieving write operation into N groups, where N is greater than or equal to a number of processes writing to the memory, determining an offset assigned to each process, the offset being a distance from a beginning of the file range at which each process starts its writing, simultaneously writing by each process to the group of the file range determined by the associated offset of each process, and moving, by each process, to the next available subsequent group when a process completes the writing. Other embodiments are also disclosed.
