Hedvig Assigned Patent

Hedvig, Inc., Santa Clara, CA, has been assigned a patent (10,067,722) developed by Lakshman, Avinash, Fremont, CA, for a “storage system for provisioning and storing data to a virtual disk.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An administrator provisions a virtual disk in a remote storage platform and defines policies for that virtual disk. A virtual machine writes to and reads from the storage platform using any storage protocol. Virtual disk data within a failed storage pool is migrated to different storage pools while still respecting the policies of each virtual disk. Snapshot and revert commands are given for a virtual disk at a particular point in time and overhead is minimal. A virtual disk is cloned utilizing snapshot information and no data need be copied. Any number of Zookeeper clusters are executing in a coordinated fashion within the storage platform, thus increasing overall throughput. A timestamp is generated that guarantees a monotonically increasing counter, even upon a crash of a virtual machine. Any virtual disk has a ‘hybrid cloud aware”‘policy in which one replica of the virtual disk is stored in a public cloud.”

The patent application was filed on July 2, 2014 (14/322,813).
