  • Systems and methods for accessing non-volatile memory and write acceleration cache
    Patent number: 10831650
    Abstract: Embodiment of a storage stack are disclosed whereby increased performance and other technical improvements are achieved by an application requesting access (e.g., asynchronously) to an address, returning a buffer, and the application issuing a buffer release when the operation is complete.
    Type: Grant

  • High performance raid operations offload with minimized local buffering
    Patent number: 10437740
    Abstract: The present technique presents a hardware mechanism by which high performance computational engines utilize external/system memory buffers for data source and sync thus requiring a minimized amount of local buffering and imposing almost no buffer or data size limitations.

  • Lock-free raid implementation in multi-queue architecture
    Patent number: 10430336
    Abstract: Systems and methods (including hardware and software) are disclosed where all common RAID storage levels are implemented for multi-queue hardware by isolating RAID stripes to a single central processing unit (CPU) core affinity. Fixed CPU affinity is used for any piece of data that may be modified. Instead of blocking CPUs that must access or modify a piece of data, the request is efficiently moved to the CPU that owns that data. In this manner the system is completely asynchronous, efficient, and scalable.

  • Auto zero copy applied to a compute element within a systolic array
    Patent number: 10389658
    Abstract: The present subject disclosure presents a hardware mechanism and usage model for using a compute element of a systolic array to handle messages from an RQ (Receive Queue) to SQ (Send Queue) without requiring a copy between queues and also minimizing the local processor's interaction with the send and receive queue hardware.

  • PCIe switch with data and control path systolic array
    Patent number: 10261936
    Abstract: The present subject disclosure provides a PCIe switch architecture with data and control path systolic array that can be used for real time data analysis or Artificial Intelligence (AI) learning. A systolic array is described which analyzes the TLPs received by an uplink port and processes the TLPs according to pre-programmed rules. Then the TLP is forwarded to a destination port. The reverse operation is described as well.
