Abstract: A method, non-transitory computer readable medium, and archive node computing device that receives an indication of each of a plurality of archived files required to service a job from one of a plurality of compute node computing devices of an analytics tier. An optimized schedule for retrieving the archived files from one or more archive storage devices of an archive tier is generated. The optimized schedule is provided to the one of the plurality of compute node computing devices. Requests for the archived files received from the one of the plurality of compute node computing device and at least one other of the plurality of compute node computing devices, wherein the requests are sent according to the optimized schedule.

Abstract: A method, device and non-transitory computer readable medium that manages read access includes organizing a plurality of requests for objects on one or more storage media, such as tapes or spin-down disks, based on at least a deadline for each of the plurality of requests. One of one or more replicas for each of the objects on the one or more storage media is selected based on one or more factors. An initial schedule for read access is generated based at least on the deadline for each of the plurality of requests, the selected one of the replicas for each of the objects, and availabilty of one or more drives. The initial schedule for read access on the one or more of the drives for each of the plurality of requests for the objects is provided.

Abstract: Technology is described for responding to service level objectives during deduplication. In various embodiments, the technology receives a service level objective (SLO); receives data to be stored at the data storage system; computes an amount of deduplication to apply to the received data responsive to the SLO; deduplicates the data to the computed amount; and stores the deduplicated data. The deduplicated data may be stored in such a manner that the data can be read in a manner that meets the SLO.
