Patents by Inventor Douglas Dumitru

Douglas Dumitru has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System, method and apparatus for accelerating fast block devices
    Patent number: 11687445
    Abstract: A device, method and system is directed to fast data storage on a block storage device. New data is linearly written to an empty write block. A location of the new data is tracked. Meta data associated with the new data is linearly written. A lookup table may be updated based in part on the meta data. The new data may be read based the lookup table configured to map a logical address to a physical address.
    Type: Grant

    Date of Patent: June 27, 2023
    Inventors: Douglas Dumitru, Samuel J. Anderson
  • Fast block device, system and methodology
    Patent number: 11455099
    Abstract: A device, memory, method and system directed to fast data storage on a block storage device that reduces operational wear on the device. New data is written to an empty write block with a number of write blocks being reused. A location of the new data is tracked. Metadata associated with the new data is written. A lookup table may be updated based in part on the metadata. The new data may be read based the lookup table configured to map a logical address to a physical address.

  • System, method and apparatus for accelerating fast block devices
    Patent number: 10860255
    Abstract: A system, method and apparatus directed to fast data storage on a block storage device. New data is written to an empty write block. If the new data is compressible, a compressed version of the new is written into the meta data. A location of the new data is tracked. Meta data associated with the new data is written. A lookup table may be updated based in part on the meta data. The new data may be read based the lookup table configured to map a logical address to a physical address. Disk operations may use state data associated with the meta data to determine the empty write block. A write speed-limit may also be determined based on a lifetime period, a number of life cycles and a device-erase-sector-count for the device. A write speed for the device may be slowed based on the determined write speed-limit.
