Examples include client access to a storage medium coupled with a server. A network input/output device for the server receives a remote direct memory access (RDMA) command including a steering tag (S-Tag) from a client remote to the server. For these examples, the network input/output device forwards the RDMA command to a Non-Volatile Memory Express (NVMe) controller and access is provided to a storage medium based on an allocation scheme that assigned the S-Tag to the storage medium. In some other examples, an NVMe controller generates a memory mapping of one or more storage devices controlled by the NVMe controller to addresses for a base address register (BAR) on a Peripheral Component Interconnect Express (PCIe) bus. PCIe memory access commands received by the NVMe controller are translated based on the memory mapping to provide access to the storage device.
