WebThat is handled by DPDK/SPDK's EAL operating system abstractions and device driver APIs. DMA memory is mapped permanently so the device driver doesn't need to perform individual map/unmap operations in the data path. NVMe PCI request submission builds the NVMe command structures containing device addresses (i.e. IOVAs when IOMMU is enabled). WebStarWind introduces StarWind NVMe-oF Initiator – a free software solution that makes any client NVMe-oF-compatible. It is the only software NVMe-oF initiator available these days. The solution is implemented as a software module that connects a host (i.e., a client) to a block storage target (i.e., remote server). The solution works with both ... laghetti audan menu
