  • Patent number: 10891266
    Abstract: A user virtual file system within a hierarchical storage system performs file handling. A user virtual file system scans, reads and analyses data or user behavior to create or modify at least one rule or metadata. The user virtual file system identifies logical or temporal relationships of files based on the at least one rule or the metadata. The user virtual file system groups identified related files in the at least one container. The user virtual file system moves the at least one container to different tiers of storage based on the at least one rule or the metadata.

  • Patent number: 10891059
    Abstract: A storage system in a clustered system may receive a first input/output (I/O) request. The storage system may include one or more storage nodes. Each of the one or more storage nodes may have a copy of a particular object stored thereon. The storage system may execute the first I/O request. Executing the first I/O request may modify data of a first object in a first storage node. The first object may be a copy of the particular object. The storage system may transfer the modified data of the first object to a master storage node. The master storage node may include a master object update descriptor list.

  • Patent number: 10803535
    Abstract: The subject invention relates to employing interactive components and execution components to facilitate power transactions. In an example, a method includes receiving a first set of data from a set of agent components, wherein the first set of data represents a purchase, a transmission, a production, a sale or a consumption of energy; and facilitating execution, by the system, of a set of contracts between a first subset of agent components and a second subset of agent components based on the first set of data. In another example, a method can further include insuring, by the system, the set of contracts against a supply surplus of energy or a production shortage of energy.

  • Patent number: 9767116
    Abstract: Responsive to receiving an identification of a new state identifier associated with the state of an object within a file from a child node, a master node updates a current state identifier for the object to the new state identifier in the master node. Responsive to a predefined user specification indicating that the new state identifier is to be broadcast to each remaining child node of a subset of child nodes in a plurality of child nodes that have a copy of the object, the master node identifies the subset of child nodes in the plurality of child nodes that have a copy of the object in the master node. The master node then broadcasts the new state identifier to the subset of child nodes that have a copy of the object.

  • Patent number: 9536085
    Abstract: In a data management system, examination of first data for malicious content by a malicious content scanner is initiated in response to a request to write first data to a data storage device. In response to the examination revealing no malicious content in the first data, the first data, a first signature representative of a version of the malicious content scanner at a time of the examination of the first data, and second data linking the first signature to the first data as read-only data are written to the data storage device.
