SNAP

NVIDIA® BlueField® SNAP and virtio-blk SNAP (storage-defined network accelerated processing) technology enables hardware-accelerated virtualization of local storage. NVMe/virtio-blk SNAP presents networked storage as a local block-storage device (e.g., SSD) emulating a local drive on the PCIe bus. The host OS or hypervisor uses its standard storage driver, unaware that communication is done, not with a physical drive, but with NVMe/virtio-blk SNAP framework. Any logic may be applied to the I/O requests or to the data via the NVMe/virtio-blk SNAP framework prior to redirecting the request and/or data over a fabric-based network to remote or local storage targets.
