Abstract: A distributed storage system includes a primary storage system and a secondary storage system. The secondary storage system stores the actual data and the primary storage system stores metadata for the actual data. The metadata references at the primary storage system may be deleted without deleting the corresponding data at the secondary storage system. Snapshots of the metadata at the primary storage system are sent to the secondary storage system. The secondary storage system can compare two metadata snapshots received from the primary storage in order to determine whether data stored at the secondary storage system has been deleted at the primary storage system for longer than a retention period. Such data may be deleted to free up storage space at the secondary storage server.

The method comprises recording process data, which is timestamped, and recording audio input from each personnel of a plurality of personnel of the process plant. The audio input is synchronized according to time with the process data. A keyword is identified from the temporally synchronized content of each audio input, and compared with the process information of one or more of an event and an equipment, for identifying at least one of a new process information and a supplementary process information related to the condition. One or more of the new process information and the supplementary process information identified for each keyword, and the plurality of events identified from the process data, are used for identifying the sequence of events associated with the condition.

Abstract: Embodiments include an event services modeling framework. The event services modeling framework includes an event services modeling editor that provides a user interface and mechanism for users to model and customize event flow configurations within a system and/or network. The user interface can be used to connect events with actions that will take place in response to the events. The system components and/or modules that need to receive the information from the events can then react and respond appropriately. Users can modify event configurations based on their own particular needs. the event services editor can be used for generating one or more event services models. The event services models may include events, conditions (rules) for processing the events, activities to be perform during event processing, subscriber modules defined for performing the activities during event processing, and a specified time for processing the events in each modeled event flow.

Abstract: A method for reconciling transactions iteratively by segregating data into homogeneous data sets. The method includes acquiring transactions from two or more systems and comparing with a set of configurable predefined matching rules. Applying, based on the result of the comparison, one or more rules on the acquired transactions. The transactions of the two or more systems are scanned and a user defined function is applied on the transactions of the two systems. A value of the user defined function is calculated. If the value of the user defined function is residual value, a configurable criteria is applied on the value of the user defined function. A residual transaction is created in one of the systems and the value of the user defined function is recalculated. If the value of the user defined function is null value, indicates the transactions are reconciled.

Abstract: In general, techniques for facilitating a distributed network (L3) subnet by which multiple independent control planes of network devices connected to physically separate L2 networks provide L2 reachability to/from a single L3 subnet. In some examples, a shared L2 network physically situated to connect a plurality of physically separate L2 networks “stitches” the L2 networks together within the respective, independent control planes of switches such that the control planes bridge L2 traffic for a single bridge domain for the separate L2 networks to the shared L2 network and visa-versa. Each of the independent control planes may be configured with a virtual IRB instance associated with the bridge domain and with a common network subnet. Each of the virtual IRBs provides a functionally similar routing interface for the single bridge domain for the separate L2 networks and allows the shared network subnet to be distributed among the independent control planes.
