  • Method and apparatus for accessing at least one memory region of SSD during failover situation in multipath system
    Patent number: 11232003
    Abstract: A first host system in a multipath storage system acts on behalf of a second host system when the second host system is unable to access a solid state drive (SSD). The first host system configures a bitmap table using an SSD controller of the first host system to access memory of the SSD associated with the second host system. The memory accessed on behalf of the second host system may be in a region including persistent memory, base address register memory and/or controller memory buffer of the second host system.

  • Non-volatile memory express over fabric messages between a host and a target using a burst mode
    Patent number: 11016911
    Abstract: Systems and methods for managing transfer of NVMeoF commands/responses between a host and a target are described. The systems and methods may initiate and convert at least one Input/Output request into at least one Non-Volatile Memory Express over Fabric (NVMeoF) command to access a storage device attached with the target device. A host may transmit the at least one NVMeoF command in a burst mode using a Remote Direct Memory Access (RDMA) Write packet to a pre-registered memory region of the target device. In response to reception of the at least one NVMeoF command, the target device may post at least one NVMeoF completion response corresponding to the at least one NVMeoF command using the RDMA Write packet to a pre-registered memory region of the host.
