Red Hat Assigned Eight Patents

Flexible deprovisioning of distributed storage
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,740,009) developed by Chen, Huamin, Westford, MA, Nielsen, Steven Travis, Bothell, WA, and Weil, Sage Austin, Madison, WI, for a “flexible deprovisioning of distributed storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Flexible deprovisioning of distributed storage is disclosed. For example, an orchestrator executes on a processor to measure a current storage demand factor based on a current count of service guests and a storage capacity of a plurality of storage nodes. A projected storage demand factor is calculated by (i) adjusting the current count of service guests with a timing factor resulting in a projected count, and (ii) combining the projected count with a storage class associated with the service guests. The orchestrator determines that the projected storage demand factor is lower than the current storage demand factor, and in response requests termination of a first storage node of the plurality of storage nodes based on the first storage node lacking an active communication session with the service guests. Cancel termination of the first storage node based on an association between the first storage node and a second storage node.”

Implementing base set of data storage features for containers across multiple cloud computing environments
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,732,868) developed by Chen, Huamin, Westford, MA, and Childs, Bradley D., Austin, TX, for “implementing a base set of data storage features for containers across multiple cloud computing environments.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Implementing a base set of data storage features for containers across multiple cloud computing environments. A container specification analyzer receives a container specification that identifies a container to be initiated, a volume to be mounted, and a native device driver to communicate with to facilitate mounting the volume. The container specification analyzer changes the container specification to generate an updated container specification that identifies a pass-through device driver to communicate with in lieu of the native device driver and identifies pass-through device driver data that identifies a data storage feature to be performed on data destined for the native device driver. The container specification analyzer returns the updated container specification for processing by a container initiator.”

The patent application was filed on August 2, 2018 (16/053,428).

Physical memory migration for secure encrypted virtual machines
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,719,255) developed by Van Riel, Henri Han, Merrimack, NH, and Tsirkin, Michael, Lexington, MA, for a “physical memory migration for secure encrypted virtual machines.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Systems and methods for migrating encrypted storage blocks in a security enhanced manner. An example method may comprise: selecting, by the hypervisor, a first storage block and a second storage block, the first storage block being associated with a virtual machine, associating the second storage block with the virtual machine, and providing, by the hypervisor, an instruction for the virtual machine to copy content of the first storage block to the second storage block.”

The patent application was filed on February 15, 2019 (16/278,005).

Virtual machine backup using snapshots and current configuration
Red Hat Israel, Ltd., Raanana, Israel, has been assigned a patent (10,713,183) developed by Frenkel, Omer, Tel Aviv, Israel, and Kolesnik, Mike, Ramat-Gan, Israel, for “virtual machine backup using snapshots and current configuration.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A computer system generates snapshot backups of a virtual machine by creating a metadata snapshot and a backup snapshot. The computer system identifies a backup request for a virtual machine operating on a host computing system, initiates a backup snapshot of storage devices in use by the virtual machine, generates a metadata snapshot of a configuration of the virtual machine, and maintains the metadata snapshot in a data store.”

The patent application was filed on November 28, 2012 (13/687,486).

Disk resize of virtual machine
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,705,865) developed by Simoncelli, Federico, Fano, Italy, for a “disk resize of a virtual machine.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An engine in a virtualization system may determine that a disk size of a disk represented by a virtual machine disk image is to be changed. In response, the engine determines whether a host is using the virtual machine disk image to run a virtual machine and also determines a file format of the virtual machine disk image. Based on the determination, the engine sends a request to change the disk size to a requested size to the host running the virtual machine or to a storage pool manager.”

The patent application was filed on February 25, 2014 (14/189,710).

Dual overlay query processing
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,698,890) developed by Nguyen, Filip, Brno, Czech Republic, Elia{hacek over, s)}, and Filip, Vysni Lhoty, Czech Republic, for a “dual overlay query processing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An example method of processing a query at a plurality of storage devices includes receiving a dual query from a client and generating a synchronous query and an asynchronous query based on the dual query. The dual query includes a set of conditions for selecting data from a set of database tables. The method further includes sending the synchronous query to a first storage device, sending the asynchronous query to a second storage device, and receiving a result set of the synchronous query. The result set of the synchronous query includes data selected from a set of database records in a set of primary database tables, which is stored in the first storage device and is a subset of the set of database tables. The method further includes marking a database record. A marked database record indicates usage of the data selected from the database record within a time period.”

The patent application was filed on September 17, 2018 (16/132,724).

Containerizing block storage service
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,678,447) developed by Hallisey, Ryan, Raleigh, NC, for “containerizing a block storage service.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Containerization of a block storage service. A scheduler component of a block storage service is initiated in a first container via a containerization technology. A log volume maintained by a host operating system is mounted to the first container to allow the scheduler component access to the log volume. An application programming interface (API) component of the block storage service is initiated in a second container via the containerization technology. The log volume is mounted to the second container to allow the API component access to the log volume of the host operating system. A volume component of the block storage service is initiated in a third container via the containerization technology. A device volume is mounted to the third container to allow the volume component access to the device volume of the host operating system.”

The patent application was filed on July 13, 2017 (15/649,079).

Quality of service enforcement and data security for containers accessing storage
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,664,415) developed by Chen, Huamin, Westboro, MA, Zheng, Feiran, Beijing, China, Watt, Stephen James, Cedar Park, TX, and Grover, Andrew, Portland, OR, for “quality of service enforcement and data security for containers accessing storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Systems and methods for Quality of Service (QoS) enforcement and data security for containers accessing storage. An example method may comprise: receiving an input/output (I/O) call initiated by a container running on a host computer system to request data from a storage device, translating the I/O call into a device emulator call to a device emulator emulating a storage device, sending the device emulator call to the device emulator, and receiving, from the device emulator, a response comprising the data retrieved from the storage device.”

The patent application was filed on June 7, 2017 (15/616,175).
