A system and method for providing erasure code protection across multiple storage devices. A data switch in a storage system connects a plurality of storage devices to a remote host. Each storage device is also connected to a controller, e.g., a baseboard management controller. During normal operation, read and write commands from the remote host are sent to respective storage devices through the data switch. When a write command is executed, the storage device executing the command sends a copy of the data to the controller, which generates and stores erasure codes, e.g., on a storage device that is dedicated to the storage of erasure codes, and invisible to the remote host. When a device fails or is removed, the controller reconfigures the data switch to redirect all traffic addressed to the failed or absent storage device to the controller, and the controller responds to host commands in its stead.

A redundant system includes devices communicably coupled via communication paths. Each device is communicably coupled via two or more of the communication paths to two or more of the other devices. Each device performs wired communication via the communication paths with the devices communicably coupled to the each device via the communication paths in a normal state. Each device includes a wireless communication unit. When each device communicates with the two or more of the other devices under a condition that malfunction occurs in two or more parts in the redundant system, the each device performs the wired communication via the communication path with a counterpart device with which the wired communication via the communication path is enabled, and switches from the wired communication via the communication path to wireless communication and continues communication with the counterpart device with which the wired communication via the communication path is disabled.

Provided are a computer program product, system, and method for using a track format code in a cache control block for a track in a cache to process read and write requests to the track in the cache. A track format table associates track format codes with track format metadata. A determination is made as to whether the track format table has track format metadata matching track format metadata of a track staged into the cache. A determination is made as to whether a track format code from the track format table for the track format metadata in the track format table matches the track format metadata of the track staged. A cache control block for the track being added to the cache is generated including the determined track format code when the track format table has the matching track format metadata.

A system may include a first node in a high-availability cluster; a second node in the high-availability cluster; a redundant interface between a network device and both the first node and the second node, wherein the redundant interface is associated with a redundancy group that designates one of the first node or the second node as a primary node in the high-availability cluster and that designates the other of the first node or the second node as a backup node in the high-availability cluster; a wireless interface of the first node, wherein the wireless interface is included in the redundant interface; and a wired interface of the second node, wherein the wired interface is included in the redundant interface.

A method for reliable data synchronization within a network is disclosed. The producer system stories data in a persistent data store and produces one or more data updates. The producer system simultaneously transmits the data updates to a consumer system and initiating storage of the data updates at the producer system. When storage of the data updates at the producer system is complete, the producer system transmits a first acknowledgment to the consumer system. The producer system determines whether a second acknowledgment has been received from the consumer system, wherein the second acknowledgment indicates that the consumer system has successfully stored the data updates at the consumer system. In accordance with a determination that the second acknowledgment has been received from the consumer system, the producer system changes the temporary status of the data updates stored at the producer system to a permanent status.

Disclosed are systems and methods for a self-contained multi-modal communication system. The multi-modal communication system comprises a first mobile telecommunication node, which provides a private telecommunication network, a layer 2 (L2) backhaul wireless transceiver, an ethernet switch and an embedded edge cloud compute device. The edge cloud compute device includes an automatic failover detection system, wherein the automatic failover detection system receives as input a plurality of network parameters and automatically performs failover and communication modality switching for one or more communication devices associated with the self-contained multi-modal communication system.

Remote control system is disclosed. The present techniques relate to a system and a method for improving connection between two devices, e.g. to enable one device to control the other. The method comprises receiving, at a remote computing device, a request from a secondary user device to diagnose a fault with the primary user device. The request is received on a first communication channel. The method further comprises a step of connecting, in response to the request, the remote computing device with the secondary user device. This is performed by using a secure communication channel which is different to the first communication channel. The method further comprises a step of sending a command message for the primary user device from the remote computing device to the secondary user device via the secure communication channel Any response to the command message is then received from the secondary user device via the secure communication channel. The response is used at least in part to diagnose the fault.
