A method includes determining, by a field instrument in an industrial process and control system, a Highway Addressable Remote Transducer (HART) mode of the field instrument. The method also includes, upon a determination, by the field instrument, that the HART mode is a HART On Demand mode, listening for a HART data signal from a HART master device; when the HART data signal is detected, communicating with the HART master device according to a HART protocol; and when the HART data signal is not detected, diverting a current supply allocated for HART communication to a BLUETOOTH Low Energy (BLE) transceiver for use in BLE communication, and communicating according to a BLE protocol.

This disclosure is directed to a computer-implemented method, systems, and devices to migrate a virtual fibre channel (VFC) connection from a first hardware communication path to a second hardware communication path within a fibre channel (FC) network prior to failure of a device in the first hardware communication path. For example, a hypervisor database may contain health status with respect to recoverable failure incidents across host bus adaptor (HBA) ports for a source HBA port and a target HBA port associated with a first VFC connection using the first hardware communication path. If it is determined that a number of recoverable failure incidents on at least one component in the first hardware communication path has occurred, migration of the first VFC connection from the first hardware communication path to a second hardware communication path may be initiated prior to actual hard failure.

Examples may include a computing platform having a host driver to get a packet descriptor of a received packet stored in a receive queue and to modify the packet descriptor from a first format to a second format. The computing platform also includes a guest virtual machine including a guest driver coupled to the host driver, the guest driver to receive the modified packet descriptor and to read a packet buffer stored in the receive queue using the modified packet descriptor, the packet buffer corresponding to the packet descriptor.

Methods, systems, and devices for redundant data bus inversion (DBI) sharing are described. A device may identify a group of channels included in a data bus. The device may determine whether the group of channels satisfies a criterion. Based on the determination, the device may allocate an overhead channel to the group of channels for a set of redundancy operations. Based on the determination, the device may allocate the overhead channel to the group of channels for a set of data bus inversion operations. The device may encode data associated with the group of channels based on the allocation of the overhead channel. The overhead channel may be included in the data bus.

Composable computing architectures with an interconnection fabric to provide high availability and fault tolerance are described. An interconnection fabric routes packets between compute resources, memory resources, and input/output (I/O) resources. A fabric manager is coupled with the interconnection fabric to receive an I/O or memory requirement for a compute workload for a host device, and to map individual I/O or memory resources from the plurality of I/O resources to individual compute resources from the plurality of compute resource and to dynamically map individual I/O resources from the plurality of I/O resources based on received resource requests.

A workgroup-computing-entity-based fail-safe/evolvable hardware core structure is disclosed which includes a 3-hierarchical-level 6-workgroup-Basic-Building-Block (6-wBBB) created to supplant the node-computing-entity-based non-fail-safe/limited evolvable von-Neumann core structure of 3-hierarchical-level 3-node-BBB, (i.e., base-level IO-devices/mid-level main memory/top-level CPU) and all the first-time fail-safe workgroup systems can be subsequently generated in the second period along the workgroup-computing evolutionary timeline. Furthermore, based on the first 6-wBBB evolvable architecture, the workgroup evolutionary processes can go up to 7 generations in creating all the necessary workgroup-computing entity-based hardware core structures, so that all the real-time intelligent workgroup-computing systems can be generated in the third period along the workgroup-computing evolutionary timeline.

Staging data on a storage element integrating fast durable storage and bulk durable storage, including: receiving, at a storage element integrating fast durable storage and bulk durable storage, a data storage operation from a host computer; storing data corresponding to the data storage operation within fast durable storage in accordance with a first data resiliency technique; and responsive to detecting a condition for transferring data between fast durable storage and bulk durable storage, transferring the data from fast durable storage to bulk durable storage in accordance with a second data resiliency technique.

A method of fault-tolerant process control includes providing a network process control system in an industrial processing facility (IPF) including a plant-wide network coupling a server to computing platforms each including computing hardware and memory hosting a software application for simultaneously supporting a process controller and another process controller or an I/O gateway. The computing platforms are coupled together by a private path redundancy network for providing a hardware resource pool. At least some of the computing platforms are directly coupled by an I/O mesh network to a plurality of I/O devices to field devices that are coupled to processing equipment. Upon detecting at least one failing device in the hardware resource pool, over the private path redundancy network a backup is placed into service for the failing device from the another process controller or I/O gateway that is at another of the computing platforms in the hardware resource pool.

Approaches for managing applications in a cluster are described. In an example, a first agent may be executing on a first programmable network adapter card installed within a first computing node within a cluster. The first agent may isolate an application executing on the first computing node. Thereafter, the application may be managed by the second computing node.

Examples include a method of performing failover of in an I/O architecture by allocating a first set of resources, associated with a first port of a physical device, to a virtual device, allocating a second set of resources, associated with a second port of the physical device, to the virtual device, assigning the virtual device to a virtual machine, activating the first set of resources, and transferring data between the virtual machine and the first port using the virtual device and the first set of resources. The method further includes detecting an error in the first set of resources, deactivating the first set of resources and activating the second set of resources, and transferring data between the virtual machine and the second port using the virtual device and the second set of resources.
