摘要： Examples are disclosed for client access to a storage medium coupled with a server. A network input/output device for the server may receive 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 may forward the RDMA command to a Non-Volatile Memory Express (NVMe) controller and access 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 may generate 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 may be translated based on the memory mapping to provide access to the storage device. Other examples are described and claimed.

摘要： Examples are disclosed for remotely initializing or booting a client or host device. In some examples, a network (NW) input/output (I/O) device coupled to a host device may connect to a remote server via a NW communication link. For these examples, modules of the network I/O device may establish a control path to a non-volatile memory express (NVMe) controller maintained at the remote server using a remote direct memory access (RDMA) protocol. Properties of a storage device controlled by the NVMe controller as well has an RDMA service tag (STag) to indicate allocated portions of the storage device may be obtained. A system basic I/O system (BIOS) may be capable of using the RDMA STag to access the storage device and load an operating system (OS) kernel and one or more device drivers to remotely boot the host device. Other examples are described and claimed.

摘要： Examples are disclosed for replicating data between storage servers. In some examples, a network input/output (I/O) device coupled to either a client device or to a storage server may exchange remote direct memory access (RDMA) commands or RDMA completion commands associated with replicating data received from the client device. The data may be replicated to a plurality of storage servers interconnect to each other and/or the client device via respective network communication links. Other examples are described and claimed.

摘要： Systems, apparatuses and methods may provide for communicating, by a common layer, with a local block storage system and communicating, by a subsystem layer that is communicatively coupled to the common layer, with one or more subsystems. Additionally, the common layer may be disassociated with one or more hardware specific components of the subsystem layer. In one example, the common layer may export one or more callback functions to the subsystem layer, wherein the callback functions include a registration and/or deregistration function.

摘要： A channel based network is provided that allows one or more hosts to communicate with one or more remote fabric attached I/O units. A split-model network driver includes a host module driver and I/O unit module driver. The host module driver and the I/O unit module driver each includes a messaging layer that allows the hosts and I/O units to communicate over the switched fabric using a push-push messaging protocol. For a host to send data, the host either initiates a RDMA write to a pre-registered buffer or initiates a message Send to a pre-posted buffer on the target. For the RDMA case, the initiator would have to send the target some form of transfer indication specifying where the data has been written. This notification can be done with either a separate message or more preferably with immediate data that is included with the RDMA write.
