Anurag Bhatnagar

Anurag Bhatnagar, a Bengaluru-based inventor, has made a significant contribution to the field of cloud storage with his latest patents. He has a total of 11 patents to his name, and his most recent inventions include "Snapshot transmission from storage array to cloud using multi-path input-output" and "Moving snapshots from a local snapshot lineage on a storage system to a cloud snapshot lineage on cloud storage."

In the first patent, Bhatnagar has developed a processing device that can communicate with a storage system comprising multiple storage devices over a network. The device is equipped with a multi-path input-output (MPIO) driver, which controls the delivery of input-output (IO) operations from the device to the storage system over selected paths through the network. The MPIO driver is further configured to create IO operation threads, to use a given IO operation thread to retrieve a given IO operation from an IO queue, to attempt to perform the given IO operation on a given target of the plurality of targets, and to return the given IO operation to the IO queue upon a failure to perform the given IO operation.

In the second patent, Bhatnagar has developed an apparatus that can identify a snapshot lineage comprising a local snapshot lineage stored on a storage system and a cloud snapshot lineage stored on cloud storage of a cloud external to the storage system. The device can select a snapshot in the local snapshot lineage to copy to the cloud snapshot lineage in accordance with a snapshot policy. Bhatnagar's invention can also create a virtual device on the storage system and link the selected snapshot to the virtual device.

Bhatnagar works in EMC IP Holding Company LLC, a multinational corporation that specializes in data storage, information security, virtualization, analytics, and cloud.
