Abstract: The management of data storage channel utilization in a computing system that has multiple users. The system receives file-level requests from requesters and then creates a history for each requester. Upon evaluating the history of each requester, the system determines whether to delay the file-level requests from entering the file system stack based on the result of the evaluation. The system delays one or more of the file-level requests if the history of the corresponding requester meets one or more criteria. If the history of the corresponding requester does not meet the criteria, the system allows the file-level requests to be passed to the file system stack without being delayed.

Abstract: The subject disclosure is directed towards partitioning a file into chunks that satisfy a chunk size restriction, such as maximum and minimum chunk sizes, using a sliding window. For file positions within the chunk size restriction, a signature representative of a window fingerprint is compared with a target pattern, with a chunk boundary candidate identified if matched. Other signatures and patterns are then checked to determine a highest ranking signature (corresponding to a lowest numbered Rule) to associate with that chunk boundary candidate, or set an actual boundary if the highest ranked signature is matched. If the maximum chunk size is reached without matching the highest ranked signature, the chunking mechanism regresses to set the boundary based on the candidate with the next highest ranked signature (if no candidates, the boundary is set at the maximum). Also described is setting chunk boundaries based upon pattern detection (e.g., runs of zeros).
