A system and a method for offloading distributed parity calculations from a server including a plurality of solid-state drives (SSDs) in communication with a host via a host interface. Each SSD includes a processor. The processor of each SSD may be configured to access a host address space via the host interface, determine parity information for data stored across a plurality of buffers in the host address space, and output the parity information to the host interface.

Systems and methods of distributed parity calculation offloading

Various implementations relate to receiving, by a first non-volatile memory device from a host, a host command including device context information of a plurality of non-volatile memory devices. The device context includes an address of a buffer of each of the plurality of non-volatile memory devices, in response to receiving the host command. The first non-volatile memory device divides portions of host data corresponding to the host command among the plurality of non-volatile memory devices. The first non-volatile memory device sends to the host a transfer request indicating transfer of each of the portions of the host data to a respective one of the plurality of non-volatile memory devices. The first non-volatile memory device sends to each of the plurality of non-volatile memory devices other than the first non-volatile memory device, a peer command based on the device context information.

Non-volatile storage device offloading of host tasks

Various implementations described herein relate to systems and methods for managing superblocks, including a non-volatile storage including a superblock and a controller configured to notify a host of a size of the superblock to a host, determine a stream that aligns with the superblock, write data corresponding to the stream to the superblock, and determine that writing the data correspond to the stream has completed.

Superblock-based write management in non-volatile memory devices

Various implementations relate to receiving, by a non-volatile memory device from a host, a host command include device context information of non-volatile memory devices. The device context includes an address of a buffer of each non-volatile memory device. In response to receiving the host command, portions of host data are divided among the non-volatile memory devices. The non-volatile memory device sends to the host a transfer request indicating transfer of each portion of the host data to a respective one of the non-volatile memory devices. The non-volatile memory device sends to another non-volatile memory device a peer command based on the device context information.
