  • System and method for implementing SSD-based I/O caches
    Patent number: 9971513
    Abstract: A method for caching a data block stored on a first storage device and onto a second storage device including determining whether a data block being requested contains a first type of data, upon a condition in which the data block contains the first type of data, writing the data block to the second storage device and upon a condition in which the data block does not contain the first type of data, determining whether a correspondingly mapped block on the second storage device contains the first type of data, and only writing the data block to the second storage device upon a condition in which the correspondingly mapped block does not contain the first type of data.

  • 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.
