  • Publication number: 20190384719
    Abstract: A device having a controller configured to execute a range crawler algorithm residing in firmware or hardware and a data table containing one or more range entries (RE's), where each of the RE's is part of a logical block address (LBA) span associated with a command instruction, and where each LBA span has one or more LBA ranges, and where each LBA range is made of one or more sequential LBA's. The device also includes a collision bitmap configured to store data associated with RE collisions between one or more LBA's and a command dispatcher configured to release selected LBA ranges that are not associated with a RE collision. The range crawler algorithm is configured to search the data table to detect collisions between the RE's.

  • Patent number: 10379747
    Abstract: A method includes receiving, by a hardware controller of a storage device and from a host device, a command to read data from or write data to a non-volatile memory device of the storage device. The method includes, responsive to receiving the command: initializing, by firmware executing at a processor of the hardware controller, a command to retrieve data from or write data to the non-volatile memory device; determining, by circuit logic of the hardware controller, a time indicative of when the firmware initialized the command; determining, by the circuit logic, a time indicative of when the command terminated; and storing, by the circuit logic and at a latency monitoring cache of the storage device, a timestamp associated with the time indicative of when the command was initialized and a timestamp associated with the time indicative of when the command terminated.

  • Publication number: 20180253250
    Abstract: A controller of a storage device is described for handling communications with a host device. In some examples, the storage device includes a wide port comprising a plurality of phys. The wide port is configured to receive, via a first phy of the plurality of phys, a signal. The controller is configured to select, based on a respective power factor associated with each respective phy of the plurality of phys and a respective performance factor associated with each respective phy of the plurality of phys, a second phy of the plurality of phys to utilize for performing an operation associated with the received signal. In such examples, the wide port is further configured to perform, using the second phy, the operation associated with the received signal.
