Multi-class heterogeneous clients in filesystem
Hewlett-Packard Development Company, L.P., Spring, TX, has been assigned a patent (10,289,338) developed by Moore, Daniel, North Carlton, Australia, and Gildfind, Andrew, Richmond, Australia, for a “multi-class heterogeneous clients in a filesystem.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number. Each node stores this information and when a change is detected, each node can request an update of the data needed by that node. A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.”

The patent application was filed on February 8, 2017 (15/428,004).

Security record transfer in computing system
Hewlett-Packard Development Company, L.P., Spring, TX, has been assigned a patent (10,275,604) developed by Lopez, Scott, Houston, TX, and Kalibjian, Jeff, Sunnyvale, CA, for a “security record transfer in a computing system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An input monitoring agent detects storage of a security record by a security scanning application, encrypts a copy of the security record, and deletes the security record. A secure transfer queue decrypts the encrypted security record, translates the security record for use by a security monitoring application, and encrypts the translated security record. An output monitoring agent predicts when a security monitoring application will attempt to import a new security file, decrypts and stores the encrypted translated security record as the new security file, and deletes the new security file when the security monitoring application has completed importation.”

The new transaction is a data modification operation performed on data blocks of the storage device. Further, the delta value indicates at least one of volume of data modified since creation of a reference snapshot and number of transactions performed since the creation. Subsequently, the updated snapshot delta value is compared with a corresponding threshold value. The threshold value is at least one of a predetermined volume of data modified and a predetermined number of transactions. A snapshot action is subsequently performed based on the comparison.”
