  • Deduplication of file
    Patent number: 10769112
    Abstract: The present invention discloses a method for deduplication of a file, a computer program product, and an apparatus thereof. In the method, the file is partitioned into at least one composite block, wherein the composite block includes a fixed-size block and a variable-size block, the variable-size block being determined based on content of the file. Then a deduplication operation is performed on the at least one composite block.

  • Dynamic modulation of cache memory
    Patent number: 10140030
    Abstract: One or more processors migrate an amount of cloud data from a non-volatile memory to a volatile cache memory. One or more processors partition the amount of cloud data into a plurality of objects of a size that allow for a satisfactory read/write throughput performance. One or more processors analyze the plurality of objects for input/output performance over a time period. One or more processors migrate a first portion of the plurality of objects back to the non-volatile memory, wherein the first portion of the plurality of objects exhibit a first input/output performance lower than a first threshold value.
