An computing device for dual-access high-performance storage for BMC to host data sharing includes a storage device, a host input/output (“IO”) domain hardware, a BMC that includes an external data connection, and a switch that includes a connection to the host TO domain hardware, a connection to the storage device, a connection to a root port in the BMC, and a connection to an end point port of the BMC. The switch is configured to connect the host TO domain hardware to the end point port of the BMC and configured to alternately connect the root port of the BMC to the storage device while uploading data from the external data connection to the storage device, and the host TO domain hardware to the storage device to permit the host TO domain hardware to access to the data uploaded from the external data connection.

Bandwidth control can be provided for input/output channels according to some aspects described herein. In one example, a system can detect an input/output (I/O) request transmitted by a software application. In response to detecting the I/O request, the system can determine a bandwidth group that corresponds to an I/O channel associated with the I/O request. The system can then determine whether bandwidth consumption of the bandwidth group exceeds a predefined bandwidth limit. If so, the system can execute a predefined policy assigned to the I/O channel for handling the I/O request.

A method for transmitting data between functions implemented on a first electronic chip of the manycore type. The first electronic chip includes a plurality of execution cores, the execution cores being grouped in clusters, the clusters being interconnected by at least two communication systems. The data transmission method includes the steps of: implementing a first function on a first cluster; implementing a second function on a second cluster, characterised in that the second function is also implemented on a third cluster distinct from the first and second clusters; and transmitting at least one data item between the first function and the second function.

Provided are a computer program product, system, and method for using at least one machine learning module to select a priority queue from which to process an Input/Output (I/O) request. Input I/O statistics are provided on processing of I/O requests at the queues to at least one machine learning module. Output is received from the at least one machine learning module for each of the queues. The output for each queue indicates a likelihood that selection of an I/O request from the queue will maintain desired response time ratios between the queues. The received output for each of the queues is used to select a queue of the queues. An I/O request from the selected queue is processed.

A storage device sharing system and a storage device sharing method are provided. The storage device sharing system includes a storage device, a first chip and a second chip. The first chip and the second chip are configured to enter a toggle mode and an arbitration mode. In the toggle mode, the first chip that acts as the master controls the arbitration potential to a first control potential and a second control potential, and communicates with the storage device in response to the arbitration potential being the first control potential, and the second chip that acts as a slave communicates with the storage device in response to the arbitration potential being the second control potential.

In one embodiment, an apparatus comprises: an endpoint circuit to perform an endpoint operation on behalf of a host processor; and an input/output circuit coupled to the endpoint circuit to receive telemetry information from the endpoint circuit, encode the telemetry information into a virtual bus encoding, place the virtual bus encoding into a payload field of a control message, and communicate the control message having the payload field including the virtual bus encoding to an upstream device. Other embodiments are described and claimed.

During operation, the system receives, by a master node, a first I/O request with associated data, wherein the master node is in communication with a first plurality of storage drives via a switch based on a network protocol, wherein the master node and the first plurality of storage drives are allowed to reside in different cabinets, and wherein a respective collection of storage drives are coupled to a converter module, which is configured to convert data between the network protocol and an I/O protocol used to access the storage drives. The system identifies, by the master node, a first collection of storage drives from the first plurality on which to execute the first I/O request. The system executes, based on a communication via the switch and a converter module associated with the first collection of storage drives, the first I/O request on the first collection of storage drives.

Disclosed herein is a technique for managing I/O requests transmitted between a computing device and a storage device. According to some embodiments, the technique can be implemented by the computing device, and include providing at least one I/O request to a submission queue configured to store a plurality of I/O requests. In conjunction with providing the at least one I/O request, the computing device can identify that at least one condition associated with the submission queue—and/or a completion queue—is satisfied, where efficiency gains can be achieved. In turn, the computing device can (1) update an operating mode of the storage device to cause the storage device to cease interrupt issuances to the computing device when I/O requests are completed by the storage device, and (2) update an operating mode of the computing device to cause the computing device to periodically check the completion queue for completed I/O requests.

A data processing system includes a memory, a group of input/output (I/O) devices, an input/output memory management unit (IOMMU). The IOMMU is connected to the memory and adapted to allocate a hardware resource from among a group of hardware resources to receive an address translation request for a memory access from an I/O device. The IOMMU detects address translation requests from the plurality of I/O devices. The IOMMU reorders the address translation requests such that an order of dispatching an address translation request is based on a policy associated with the I/O device that is requesting the memory access. The IOMMU selectively allocates a hardware resource to the input/output device, based on the policy that is associated with the I/O device in response to the reordering.
