  • Patent number: 11163630
    Abstract: A system and method for reducing execution errors make by a software service are disclosed. The service has several features whose execution paths are switched on or off by corresponding feature toggles, i.e. flags in a configuration database. The performance, and especially error generation, of each feature is monitored automatically and an instantaneous error rate is produced. When the error rate exceeds a given threshold error rate for a particular feature, the corresponding toggle is disabled in the configuration database and the service is triggered to restart using the updated toggles, thereby disabling the problematic feature. The system and method also determine whether the error rate increased due to a transient error condition, such as a data link drop or a secondary service restart, and re-enable the toggle when the error condition has passed.

  • Patent number: 11102282
    Abstract: This present invention is directed towards a container orchestration method such as Kubernetes in which pods monitor themselves to determine if they are likely to require additional resources or vertical scaling within a given timeframe. If the pod determines that it will need additional processing power it notifies the state manager to begin allocating these resources on the same node or a different virtual or physical node before the CPU usage reaches 99%+. The state manager receives this request and allocates the necessary resources ahead of time. When the pod's CPU usage reaches 99%+, the state manager will remove the pod from the existing node and moves the application to the new pod on a different node in which sufficient resources are allocated. This invention brings about efficient utilization of nodes.

  • Patent number: 10725881
    Abstract: A method for locating and isolating a failed node of an electromechanical management bus in a communication device. The method includes, in a communication process, an SHMC in operation records communication states of electromechanical management buses; the SHMC in operation performs calculation and analysis operations on data associated with the communication states, and determines whether there is an irrecoverable communication abnormality in a corresponding bus; if so, the SHMC sends, by means of a normal electromechanical management bus, a command to an electromechanical management node subordinate to the abnormal electromechanical management bus, such that the electromechanical management node controls a corresponding mechanical switch of the bus, coordinates respective nodes of the abnormal electromechanical management bus to conduct mutual communication tests with each other, locates a failed node, and returns location information of the failed node.

  • Patent number: 10719446
    Abstract: A method and apparatus for implementing a buffer cache for a persistent file system in non-volatile memory is provided. A set of data is maintained in one or more extents in non-volatile random-access memory (NVRAM) of a computing device. At least one buffer header is allocated in dynamic random-access memory (DRAM) of the computing device. In response to a read request by a first process executing on the computing device to access one or more first data blocks in a first extent of the one or more extents, the first process is granted direct read access of the first extent in NVRAM. A reference to the first extent in NVRAM is stored in a first buffer header. The first buffer header is associated with the first process. The first process uses the first buffer header to directly access the one or more first data blocks in NVRAM.

  • Patent number: 10715596
    Abstract: A server system and a control method for a storage unit are provided. The server system includes multiple modular devices and a connection device. The storage unit in the modular devices includes a transmission interface expander. The transmission interface expander detects whether connects a former modular device, and sets the storage unit as a slave device of the former modular device when the transmission interface expander connects the former modular device. When the transmission interface expander does not connect the former modular device, the transmission interface expander is set as a storage node and communicates to the external server, and the latter storage unit connected behind the transmission interface expander becomes a slave device of the transmission interface expander.

  • Patent number: 10708148
    Abstract: Many services measure quality of service (QoS) according to abstract metrics based on general heuristics of QoS determinants (e.g., VoIP service providers may presume that QoS is predominantly determined by network performance). However, users' QoS perceptions are often based on their experiences with particular activities of the service, which may utilize different service paths having different QoS determinants. Therefore, QoS may be measured by identifying the activities of the service, and the dependencies among the components of such services; for respective activities and dependencies, identifying a service path from the source to the user, and the segments comprising the service path; measuring the quality of the segments of the service path; and calculating the QoS of the activity according to the QoS of the segments of the service path providing the activity. This approach may yield QoS information of greater relevance to the users' experience and with greater analytic value.
