Nvidia Assigned Patent

Nvidia Corporation, Santa Clara, CA, has been assigned a patent (11977452) developed by Wang, Jin, Cupertino, CA, and Nazari, Siamak, Mountain View, CA, for “efficient IO processing in a storage system with instant snapshot, xcopy, and UNMAP capabilities.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for a storage system to process input and output operations. The method includes receiving writes over time to an address at a base virtual volume, storing each of the writes in a physical storage at a new location that is without existing data, tagging each stored write with a different generation number to distinguish between different versions of data written to the address at the base virtual volume, receiving a read of the address at the base virtual volume, and, in response to the read of the address at the base virtual volume, returning one of the stored writes that is tagged with a newer generation number than a remainder of the stored writes.”

The patent application was filed on 2023-01-26 (18/101864).
