  • Tiered heterogeneous fast layer shared storage substrate apparatuses, methods, and systems
    Patent number: 10257274
    Abstract: A storage system for organizing and maintaining metadata in a distributed network. The system includes: a network; a plurality of distributed nodes configured to communicate through the network; a plurality of block devices configured to communicate with the plurality of distributed nodes through the network; and a management server configured to communicate with each of the plurality of distributed nodes and block devices and further configured to arbitrarily associate metadata and data to any of the plurality of distributed nodes such that a global copy of the metadata does not exist in one or more fixed locations known to all distributed nodes.
    Type: Grant
    Filed: September 15, 2015
    Date of Patent: April 9, 2019
    Assignee: FOUNDATION FOR RESEARCH AND TECHNOLOGY—HELLAS (FORTH)
    Inventors: Angelos Bilas, Markos Fountoulakis, Spyros Papageorgiou, Tryfon Farmakakis

  • Storage I/O path partitioning to eliminate I/O interference in consolidated servers
    Patent number: 9268702
    Abstract: A method for storage input/output (I/O) path configuration in a system that includes at least one storage device in network communication with at least one computer processor; the method comprising providing in the I/O path into at least: (a) a block-based kernel-level filesystem, (b) an I/O cache module controlling an I/O cache implemented on a first computer readable medium, (c) a journaling module, and (d) a storage cache module controlling a storage cache implemented on a second computer readable medium, the second computer readable medium having a lower read/write speed than the first computer readable medium. Furthermore, the steps of translating by the filesystem, based on computer executable instructions executed by the at least one processor, a file I/O request made by an application executed by the at least one computer processor into a block I/O request and fulfilling by the at least one processor the block I/O request from one of the I/O cache and the storage cache complete the I/O operation.
