Abstract: Methods, non-transitory computer readable media, and computing devices that accelerate data access requests. With this technology, a hierarchy of a plurality of objects is inserted into a location database. Each of at least a subset of the plurality of objects comprises a physical storage location for data stored in a filesystem. One or more of the plurality of objects includes an object version number and a parent version number of a parent one of the plurality of objects. A determination is made when an invalidation event has occurred in the filesystem. The invalidation event is associated with one of the plurality of objects. The object version number for the one of the plurality of objects is modified to invalidate one or more of the subset of the objects, when the determining indicates that the invalidation event has occurred in the filesystem.

Abstract: A method, non-transitory computer readable medium, and device that assists with performing global data deduplication on data blocks across different volumes includes identifying at least two data blocks stored in two or more storage volumes. It is determined whether the at least two data blocks are classified as a shared data block. A new data volume signature is created when the at least two data blocks are determined to be shared. One of the at least two data blocks that are determined to be shared is deleted and the other one of the at least two data blocks and the created signature in one of the two or more storage volumes is stored.

Abstract: A method, non-transitory computer readable medium, and device that assists with performing data deduplication on data blocks includes receiving a plurality of data blocks, wherein each of the received plurality of data blocks are of an equal memory size. Each of the received plurality of data blocks are split into a plurality of segments with a segment size less than the equal memory size. Duplicate data is identified within each of the plurality of segments for each of the received plurality of data blocks. One occurrence of the identified duplicate data is stored from each of the received plurality of data blocks into a new data block.

Abstract: Presented herein are mass data storage networks, file system protocols, non-transitory machine readable devices, and methods for storing data blocks in mass data storage systems. Methods for storing data blocks in a file system are disclosed which include: receiving by storage controller of the data storage system a request to write a data file to a system storage module; determining whether the data file includes a sub-K data chunk that is less than approximately four kilobytes; identifying a packed block that stores a plurality of sub-K data chunks and has sufficient storage space available to store the sub-K data chunk; and placing, by the storage controller in the packed block, the sub-K data chunk and a corresponding data length and a respective offset identifying a location of the sub-K data chunk in the packed block.

Abstract: Methods and systems for a storage server are provided. One method includes storing data at a first storage tier by a processor executable storage operating system; tracking the data stored at the first storage tier for moving the data to a second storage tier; transferring the data from the first storage tier to the second storage tier; and updating a data structure that tracks a transfer block number of a block that stores the data, where the transfer block number is based on a virtual identifier, a generation count and an offset value of a storage chunk that is a portion of a physical volume block number address space.
