Nutanix Assigned Patent

Disaster rollback across heterogeneous storage

Nutanix, Inc., San Jose, CA, has been assigned a patent (10,152,386) developed by Ramachandran, Parthasarathy, Palo Alto, CA, Bhattacharyya, Manosiz, San Jose, CA, and Chandrasekaran, Karthik, Bangalore, India, for an “efficient disaster rollback across heterogeneous storage systems.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems for storage system rollover and rollback. A data mover agent is installed on a source storage system to capture disaster recovery data and send to a target system. Upon receiving a rollover event signal, a virtualized controller creates one or more replica user virtual machines running on the target system that serve to replicate functions of the user virtual machines from the source storage system. The virtualized controller on the target system converts the target disaster recovery data from a first format to a second format to facilitate use of the target disaster recovery data by the replica user virtual machines. Rollback is initiated when the target system receives a rollback event signal. Differences in the data that have occurred between the rollover event and the rollback signal are calculated and sent to the rollback system. The calculated differences are applied to a registered snapshot on the rollback system.

The patent application was filed on July 29, 2016 (15/224,358).
