Abstract: A data object management scheme for storing a large plurality of small data objects (e.g., image files) in small number of large object stack file for storage in secondary storage (e.g., hard disks). By storing many individual data objects in a single object stack file, the number of files stored in the secondary storage is reduced by several orders of magnitude, from the billions or millions to the hundreds or so. Index data for each object stack file is generated and stored in primary storage to allow efficient and prompt access to the data objects. Requests to store or retrieve the data objects are made using HTTP messages including file identifiers that identify the files storing the data objects and keys identifying the data objects. A file server stores or retrieves the data object from secondary storage of a file server without converting the requests to NSF or POSIX commands.

Abstract: Methods and apparatus teach a digital spectrum of a file for use in determining positional relationships between groups of files. The digital spectrum is used to reveal distances between the files to sort into groups of related files. Representatively, files determined by a nearest neighbor method to be related are sorted into groups of related files. In turn, the groups of related files are determined to be related, or not, according to positional location in N-dimensional space. A centroid location for each group of related files is determined, and a distance value from that centroid location to each member file of the group of related files is determined. In turn, centroid-to-centroid distance values are determined between each group of related files and rank-ordered. Comparing the centroid-to-centroid distance values and the distance values between centroid locations and files of the groups of related files reveals relatedness, or not, of groups of files.
