Abstract: 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.

Abstract: Provided are a computer product, method, and system to virtualize target system storage resources as virtual target storage resources. Target storage resources available at a target system are discovered over a network. A configuration is determined of virtual target storage resources mapping to the target storage resources for a host node. The configuration is registered with a virtual target. The configuration maps the virtual target storage resources to the target storage resources at the target system and an access control list of the host node allowed to access the virtual target storage resources. A query is received from the host node for the target storage resources the host node is permitted to access according to the access control list. Host discovery information is returned to the requesting host node indicating the virtual target storage resources the requesting host node is provisioned to access from the virtual target.

Abstract: Provided are a computer product, method, and system to dynamically provide discovery services for host nodes of target systems and storage resources in a network. Discover on storage resources available at target systems. An access control list indicates subsets of the host nodes that can access the storage resources at the target systems. A query is received from a requesting host node comprising one of the host nodes for storage resources the host node is permitted to access according to the access control list. Host discovery information is returned to the requesting host node indicating the storage resources the requesting host node is provisioned to access, wherein the requesting host node establishes a connection with the target systems indicated in the returned host discovery information to access the storage resources the requesting host node is provisioned to access indicated in the access control list.

Abstract: Provided are a computer product, method, and system to generate a virtual subsystem to process read and write requests to storage devices. A virtual subsystem is configured in the memory to provide a representation of a subsystem presented to at least one host system. The at least one host system is to communicate with the virtual subsystem to access the at least one storage device. At least one virtual namespace is configured in the memory for the virtual subsystem. Each of the at least one virtual namespace maps to at least one physical namespace in at least one storage device. Each virtual namespace is assigned to one host system to use to direct read and write requests to the at least one physical namespace of the at least one storage device assigned to the virtual namespace.

Abstract: Methods and apparatus related to enabling individual NVMe (Non-Volatile Memory express) IO (Input Output or I/O) queues on differing network addresses of an NVMe controller are described. In one embodiment, a plurality of backend controller logic is coupled to a plurality of non-volatile memory devices. One or more virtual controller target logic (coupled to the plurality of backend controller logic) transmit data from a first portion of a plurality of IO queues to a first backend controller logic of the plurality of the backend controller logic. The one or more virtual controller target logic transmit data from a second portion of the plurality of IO queues to a second backend controller logic of the plurality of backend controller logic. Other embodiments are also disclosed and claimed.

Abstract: Examples are disclosed for moving data between a network input/output (I/O) device and a storage subsystem and/or storage device. In some examples, a network I/O device coupled to a host device may receive a data frame including a request to access a storage subsystem or storage device. The storage subsystem and/or storage device may be located with the network I/O device or separately coupled to the host device through a storage controller. One or more buffers maintained in a cache for processor circuitry may be used to exchange control information or stage data associated with the data frame to avoid or eliminate use of system memory to move data to or from the storage subsystem and/or storage device. Other examples are described and claimed.

Abstract: In some embodiments of the present invention, host systems and/or devices are made to be capable of employing asynchronous or synchronous modes. For example, for storage devices capable of finishing I/O requests in a sufficiently small amount of time, e.g., a few microseconds, host system software may perform the storage I/O request synchronously by polling for a completion.

In this regard, a network interface controller is introduced including a non-coherent bus interface to communicatively couple with devices of a system through a non-coherent protocol, the non-coherent bus interface to facilitate discovery of the network interface controller by an operating system, a coherent bus interface to communicatively couple with devices of the system through a coherent protocol, and a coherency engine to perform coherent transactions over the coherent interface including to snoop for writes on system memory. Other embodiments are also disclosed and claimed.

Abstract: A method and apparatus for transmitting data packets between a client and a server comprising, a network node receiving a data packet from a client; determining whether an identity (hereafter session id) exists for a communication session with the client. The network node transmits the data packet to a server if no session id exists. The server generates the session id, and transmits the session id to the network node. The network node transmits subsequent data packets received from the client to the server along with the session id. The server transmits subsequent data packets to the network node along with the session id. The network node removes at least the session id prior to transmitting the data packets to the client.

Abstract: A bus bridging method, a bus bridge and a bus agent are described. In a bus agent provides to a bus bridge a read data request targeting a data source bridged by the bus bridge. The read data request includes a read address indicating a starting storage location of the requested data, and a read size indicator indicating the size of the requested data. The bus bridge, in response, facilitates provision of the requested data to the bus agent. The facilitation includes streaming buffered ones of the requested data to the bus agent through one or more successive streaming connections to the bus bridge by the bus agent.
