    Abstract: The data contents of memory systems are usually protected via an EDC system. When an error is present in the memory system, the EDC system can only recognize this error after the readout of faulty data. A memory system, wherein a respective check word is co-stored together with a data word, comprising: an error monitoring system that generates said check word from a data word to be written in and from a write address according to a predetermined formation rule, the formation rule being an EDC code before the check word in common with the data word to be written in is stored under said write address, and that generates a check word anew according to the EDC code based on a data word to be read out from the memory system, compares bits of the check word to K-bits stored for the data word and, given inequality, draws conclusions about a type of error from a pattern of equal and unequal K-bits, what is referred to as the syndrome pattern; and an internal read event that is implemented before storing a data word to be written under its write address, whereby the error monitoring system implements the error check according to feature b).

    Abstract translation: 存储系统的数据内容通常通过EDC系统进行保护。 当存储器系统出现错误时，EDC系统只能在读出故障数据后识别该错误。 一种存储器系统，其中相应的检查字与数据字一起共存，包括：误差监测系统，其根据预定的形成规则从写入地址的写入数据字生成所述校验字， 在与要写入的数据字共同的检查字之前的形成规则是存储在所述写地址下的EDC码，并且根据要从中读出的数据字根据EDC码重新产生校验字 存储器系统将检查字的位与存储为数据字的K位进行比较，并且给定不等式从相等和不等的K位的模式中得到关于错误类型的结论，称为综合征模式 ; 以及在存储要写入其写入地址的数据字之前实现的内部读取事件，由此错误监视系统根据特征b）实现错误检查。

    Abstract: A method comprises executing a testing operation on a plurality of redundant components of an edge device. In one example, based, at least in part, on the testing operation, at least one redundant component of the plurality of redundant components is identified as having an operational issue, and the at least one redundant component is deactivated in response to the identifying. One or more remaining redundant components of the plurality of redundant components are utilized in one or more operations following the testing operation.

    Abstract: A customer may use a disaster recovery service to generate a disaster recovery scenario in order to make certain resources available to the customer in the event of a data region failure. The customer may specify a recovery point objective, a recovery time objective and a recovery data region for the scenario. Accordingly, the disaster recovery service may coordinate with one or more other services provided by the computing resource service provider to reproduce the customer resources and other resources necessary to support the customer resources. These reproduced resources may be transferred to the recovery data region based at least in part on the parameters specified by the customer. In the event of a data region failure, the disaster recovery service may update the domain name system to resolve any customer requests for the customer resources to the recovery data region.

    Abstract: In one embodiment, an audio device includes a plurality of ports. The audio device receives, from a first network via a first port included in the plurality of ports, at least one of a first audio signal and a first control signal. The audio device transmits the at least one of the first audio signal and the first control signal to an audio output device. In case of a fault associated with the first port, the audio device transmits at least one of a second audio signal and a second control signal to the audio output device, where the at least one of the second audio signal and the second control signal is received from a second network via a second port included in the plurality of ports.

    Abstract: Technical solutions are described for providing a redundant processor. An example processing unit includes a source processor coupled with a system communication bus via a first communication line; a backup processor coupled with the system communication bus via a second communication line; and an inter-microprocessor communication channel for communication between the source processor and the backup processor. The backup processor monitors for a failure of the source processor by monitoring the first communication line for communication messages being transmitted by the source processor. The backup processor determines a failure of the source processor in response to an absence of the communication messages on the first communication line for a predetermined duration. The backup processor, in response to a failure of the source processor, takes over control of communication of the processing unit by sending a status update on the inter-microprocessor communication channel.
