Red Hat Assigned Thirteen Patents

Custom object paths for object storage management
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,324,919) developed by Chen, Huamin, Westboro, MA, for a “custom object paths for object storage management.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A processing device receives a request that identifies an object to store in a storage system. The request includes a custom path for the object that represents content of the object. The processing device selects one or more other objects in the storage system that has a respective custom path that is similar to the custom path in the request. The one or more other objects that have the respective custom path that is similar to the custom path in the request includes content that is similar to the content of the object that is identified in the request. The processing device determines which data store in the storage system stores the one or more other objects that have the respective custom path that is similar to the custom path in the request, and routes the object identified in the request to a storage node corresponding to the data store to store the object in the data store with the one or more other objects.”

Fast evacuation of cloned disk to storage device
Red Hat Israel, Ltd., Ra’anana, Israel, has been assigned a patent (10,324,653) developed by Hadas, Arik, Herzliya, Israel, and Lipchuk, Maor, Tel-Aviv, Israel, for a “fast evacuation of a cloned disk to a storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for fast evacuation of a cloned disk to a storage device includes a source storage device generating a first write volume, where new written data is stored in the first write volume. A destination storage device generates a second write volume, where the new written data is also stored. The destination storage device generates a delta volume in a cloned disk, which is also located in the destination storage device. Differences between a template volume and a modified template volume are stored to the delta volume. The destination storage device merges the template volume and the delta volume, creating a second modified template volume.”

Transferring objects between different storage devices based on timestamps
Red Hat, Inc., Raleigh, NC, has been assigned a patent (10,235,382) developed by Avati, Anand Vishweswaran, Mountain View, CA, and Suryanarayan, Amar Tumballi, Shimoga, India, for “transferring objects between different storage devices based on timestamps.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed file system includes a plurality of computing devices that are coupled to a plurality of storage devices. A first computing device transfers objects to an additional computing device. The first computing device determines times when multiple computing devices, including the first computing device, transferred objects to the additional computing device. The first computing device identifies the earliest of the times and may store this information on the additional computing devices. A second computing device resumes transferring data to the additional computing device when the first computing device becomes unavailable or inoperable. The second computing device may use the earliest of the times to determine which objects should be transferred to the additional computing device.”

Red Hat Israel, Ltd., Raanana, Israel, has been assigned a patent (10,228,961) developed by Lipchuk, Maor, Rishon Letzion, Israel, and Erez, Daniel, Tel-Aviv, Israel, for a “live storage domain decommissioning in a virtual environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Implementations of the disclosure provide for live storage domain decommissioning in a virtual environment. A method of the disclosure includes identifying, by a processing device, a storage domain to decommission from a storage system. The storage domain comprises a plurality of disk images. It is determined whether the disk images are associated with a virtual machine. Thereupon, the disk images are hot-unplugged from the virtual machine. Responsive to detecting that the disk images are unplugged from the virtual machine, the disk image is deleted from the storage domain and the storage domain is removed from the storage system.”
