Abstract: Verified snapshots are generated by obtaining, from one of a plurality of first nodes, a difference between a common data at a first time point and the common data at a second time point that is different from the first time point, generating a first snapshot of the common data at the first time point based on the difference, obtaining a hash of the common data at the first time point from one of the plurality of first nodes, and verifying the first snapshot at the first time point with the hash of the common data at the first time point.

Abstract: A distributed data storage system includes first and second data storage systems (DSSs) at respective sites and a cloud gateway at a third. The first DSS remotely mirrors data using synchronous and asynchronous channels both employing a block-based protocol (e.g., SCSI). The second DSS is connected to the synchronous channel to provide synchronous backup to the first DSS. The cloud gateway is connected to the asynchronous channel and has a cloud storage connection to a cloud storage system, the cloud storage connection using a wide area network interface and employing an object-based protocol. The cloud gateway (1) provides asynchronous backup to the first DSS via the asynchronous channel, and (2) uses the cloud storage connection to access object-based cloud data storage to store data of the asynchronous backup. The use of the cloud gateway and cloud storage system for an asynchronous third mirror enhances reliability/resiliency in a cost-effective manner.

Abstract: A requirements-traceability system extracts and classifies project requirements stored in a set of source documents. If a source document is unstructured, such as a natural-language word-processing file, the system uses a self-learning or cognitive natural-language tool to inferentially infer requirements in that document. Each requirement may be composed of more detailed sub-requirements in parent-child relationships. Requirements are reclassified into a standardized classification scheme and stored in a standardized hierarchical data structure in which each level corresponds to a requirement's relative degree of granularity. The tree is updated whenever requirements are revised, allowing users and downstream applications to bidirectionally trace each requirement's ancestors and descendants and to review and audit revision histories of the project's entire requirements hierarchy.
