Abstract
A computer implemented method implemented by at least one processor performing executable instructions aggregates several file block variant commitments into a fewer number of parallel file write operations. Using the method, a system and apparatus intermediates between a central file service and distributed virtual machine data center servers. Requests for file block variants are redirected to the location of the freshest retention. Each data center has a non-transitory file block variant store locally attached. Each file block librarian provides a file system view to each virtual machine. Several Virtual Machine Data Centers are coordinated by a tracker which locates, redirects, and retrieves any file block variant within its name space or a name subspace delegated to a librarian.
Claims1
A computer-implemented method of operation for at least one processor to operate as a versioned file block location tracker apparatus for intermediation between a plurality of librarian circuits and a remote file server, the method comprising:
- receiving, from a processor core via a local network interface, a plurality of file block commit request indicia into a non-transitory media for various file extents of a version controlled file;
- storing said plurality of file extents into a local non-transitory store coupled to the file block write/acknowledgement circuit;
- transmitting an acknowledge indicia for a file commit to a sender of file block commit request, by means of a file block write/acknowledgement circuit coupled to the local network interface;
- incrementing a number of unfulfilled file block commit requests of file block commit request indicia yet unfulfilled for the version controlled file;
- upon exceeding a threshold of parallelism of a count of unfulfilled file block commit requests, triggering a file write operation, according to ranks of parallelizable execution and regardless of order of reception into the non-transitory media store, for all stored file extents of the version-controlled file into a remote multi-disk non-transitory media;
- and
- reinitializing the count of the number of unfulfilled file block commit request indicia, whereby throughput of virtual machines attached to the librarian circuits;
- and
- releasing a resource for reuse as soon as a write acknowledgement is received by the librarian,
- wherein data at a primary volume are synchronized with data at a secondary volume.
