The present invention concerns a method for switching, by a local processing unit (1,2) of a flight control system of an aircraft, configured to control at least one local actuator, connected to at least one local sensor and connected via at least one link (3,4) to an opposite processing unit (2,1) configured to control at least one opposite actuator and be connected to at least one opposite sensor, said local processing unit (1,2) being further configured to be connected to backup communication means (13,14) enabling data exchanges between the local processing unit (1,2) and the opposite processing unit (2,1) in the case of failures of the links connecting same (3,4), said backup communication means comprising an array of sensors or actuators (13) and/or a secure onboard network for the avionics (14), comprising steps of: •—sending, to the opposite processing unit (2,1), acquisition data relative to the at least one local sensor and actuator data relative to the at least one local actuator, •—receiving, from the opposite processing unit (2,1), acquisition data relative to the at least one opposite sensor and actuator data relative to the at least one opposite actuator, •—receiving an item of opposite health data and determining an item of local health data, •—switching said local processing unit (1,2) from a first state to a second state chosen from an active state (15), a passive state (16) and a slave state (18), depending on the opposite health data received and the local health data determined.

When mounting hardware which is coupled to another portion by a plurality of paths with different applications, despite the hardware being a single device, and a failure occurs in any of the paths, there is a risk that the failure may propagate to other components unless the other paths are also blocked. In order to solve the problem described above, in a storage apparatus to which a device coupled by a plurality of coupling paths with different applications can be mounted, the present invention determines a block range at the time of an occurrence of a failure to be a device and a plurality of coupling paths coupled to the device, manages the block range, and upon an occurrence of a failure, executes failure handling which involves blocking an appropriate block range determined in advance by referring to the information.

An electronic apparatus and a detection method using the same are provided. The electronic apparatus includes a processor, a platform controller, and an auxiliary controller. The processor includes a first bus compatible with a first standard. The platform controller is coupled to the processor, and the processor is connected to peripheral devices of the electronic apparatus through the platform controller or the first bus according to the first standard. The auxiliary controller is coupled to the processor through the first bus, and the processor controls the auxiliary controller through a second bus and the platform controller. The auxiliary controller receives a detection signal to detect the processor, the platform controller, or at least one of the peripheral devices in the electronic apparatus through the first bus compatible with the first standard according to the detection signal.

A method for performing initial registration is provided. The method includes receiving a server timeout message, the server timeout message including at least a field set to a value equal to a value received during a first registration. The method further includes initiating restoration procedures by performing an initial registration.

According to an example, a retransmission sequence involving non-idempotent primitives in a fault-tolerant memory fabric may be modified. For example, a redundancy controller may request a sequence to access a stripe in the fault-tolerant memory fabric, wherein the sequence involves a non-idempotent primitive. In response to determining an expiration of a time threshold for the non-idempotent primitive, the redundancy controller may read other data in other cachelines in the stripe, calculate a new parity value by performing an idempotent exclusive-or primitive on the new data with the other data in the stripe, and write the new parity to the stripe using an idempotent write primitive.

Failover of a virtual function exposed by an SR-IOV adapter of a computing system, including: instantiating, by a hypervisor, a standby virtual function in the computing system; detecting a loss of communication between a logical partition and an active virtual function mapped to the logical partition; placing the active virtual function and the standby virtual function in an error state; remapping the logical partition to the standby virtual function; and placing the standby virtual function in an error recovery state.

A system and method for responding to a virtual machine (VM) network failure for a host in a network partition in a high availability (HA) cluster. The method includes providing a plurality of network partition response options; and receiving a selection of a first network partition response option from the plurality of network partition response options, the selected first network partition response option causing a processor to transfer execution of a VM on the host to a second host that has VM network connectivity upon detecting a VM network failure for the host.

A biometrics hub may establish a session with a first biometric device, receive first biometric data of a user from the first biometric device, establish a session with a second biometric device, receive second biometric data of the user from the second biometric device, and store the first biometric data and the second biometric data at the biometrics hub. The biometrics hub may further detect a power event associated with at least one of the first biometric device or the second biometric device, and change, in response to detecting the power event, a schedule for processing at least one of the first biometric data or the second biometric data.

The present disclosure identifies topologies of a computer network where one network appliance may be configured as a master network appliance and where that master network appliance may communicate over a network communication interface with one or more slave network appliances. Computer networks of the present disclosure may include a switch and a firewall where the switch may be coupled to several network appliances via different network communication interfaces.
