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.

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.

Management of accesses to target storage resources

A computer product, method, and system to generate a virtual subsystem to process read and write requests to storage devices. A virtual controller is configured in a memory device to provide a representation of a controller in a computer system. At least one virtual storage is configured in the memory device. A virtual storage is assigned a quantity of physical storage configured in a plurality of storage devices, wherein the virtual storage maps to addresses in the quantity of physical storage. At least one virtual storage is assigned to a virtual controller. A host is assigned to the virtual storage assigned to the virtual controller. The host assigned the virtual storage is allowed to direct read and write requests to the quantity of physical storage assigned to the virtual storage.

Aspects of the embodiments are directed to systems, devices, and methods for accessing storage-as-memory. Embodiments include a microprocessor including a microprocessor system agent and a field programmable gate array (FPGA). The FPGA including an FPGA system agent to process memory access requests received from the microprocessor system agent across a communications link; a memory controller communicatively coupled to the system agent; and a high speed serial interface to link the system agent with a storage system. Embodiments can also include a storage device connected to the FPGA by the high speed serial interface.

Management of virtual target storage resources by use of an access control list and input/output queues

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.

Embodiments of the present disclosure may relate to a compute offload controller that may include a parser to parse a received compute offload command, and identify a block-based compute descriptor based at least in part on the compute offload command. In some embodiments, the compute offload controller may further include an offload executor to perform an operation on data in a block-based storage device based at least in part on the block-based compute descriptor. In some embodiments, the block-based compute descriptor may include a virtual input object, a virtual output object, and a compute type identifier. Other embodiments may be described and/or claimed.

Compute offload in block storage using virtual objects

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.

Disaggregating block storage controller stacks

In general, in one aspect, the disclosures describes a method that includes receiving multiple ingress Internet Protocol packets, each of the multiple ingress Internet Protocol packets having an Internet Protocol header and a Transmission Control Protocol segment having a Transmission Control Protocol header and a Transmission Control Protocol payload, where the multiple packets belonging to a same Transmission Control Protocol/Internet Protocol flow. The method also includes preparing an Internet Protocol packet having a single Internet Protocol header and a single Transmission Control Protocol segment having a single Transmission Control Protocol header and a single payload formed by a combination of the Transmission Control Protocol segment payloads of the multiple Internet Protocol packets. The method further includes generating a signal that causes receive processing of the Internet Protocol packet.

Packet coalescing

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.

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.
