Veritas Technologies Assigned Eleven Patents

Dynamic storage tiering in virtual environment
Veritas Technologies LLC, Santa Clara, CA, has been assigned a patent (10,380,078) developed by Kumar, Sanjay, Maharashtra, India, and M. G., Venkatesha, Cupertino, CA, for a “dynamic storage tiering in a virtual environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Various systems and methods for performing dynamic storage tiering in a virtual environment. For example, one method can involve identifying a location of a storage object within a virtual machine file, where the virtual machine file includes multiple storage objects. The method then involves detecting whether the storage object meets a criterion of a tiering policy. If the storage object meets the criterion, the storage object is moved from one tier of a multi-tier storage system to another tier of the multi-tier storage system.”

Recovery-chain based retention for multi-tier data storage auto migration
Veritas Technologies LLC, Santa Clara, CA, has been assigned a patent (10,372,547) developed by Zhu, Baishen, Sanford, FL, Waldrum, William D., Paso Robles, CA, and Sridharan, Srineet, Pune, India, for a “recovery-chain based retention for multi-tier data storage auto migration system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A system and method for defining retention and lifecycle policies for data backups. A media server supports a recovery-chain-based retention policy for data lifecycle management, (DLM) on a first tier of a multi-tier storage system. A recovery chain includes full backup data and at least one partial backup data. The recovery chain is maintained on the first tier until it is expired due to a new full backup operation being performed and corresponding full backup data being stored on the first tier. Based on another retention policy, the media server identifies given backup data corresponding to a recovery chain that qualifies for migration from the first tier. However, the media server determines the recovery chain includes the given backup data and other backup data that does not yet qualify for migration. In response, the media server maintains a copy of the given backup data on the first tier.”

The patent application was filed on December 29, 2015 (14/982,360).

Application performance in replication environments
Veritas Technologies LLC, Santa Clara, CA, has been assigned a patent (10,338,834) developed by Dighe, Sumit, and Marathe, Shailesh, Maharashtra, India, for an “application performance in replication environments.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Disclosed herein are methods, systems, and processes to improve application performance in replication environments. A read command configured to cause a read operation to be performed on a unit of storage in a data volume is received. A state of a lock is determined. The state of the lock indicates whether a write operation is ongoing, and the write operation results in data being written to a storage replication log and to the data volume. The write operation is ongoing because writing the data to the storage replication log and to the data volume has not completed. In response to a determination that the write operation is not ongoing, the read operation is allowed to be performed on the unit of storage.”

The patent application was filed on September 29, 2016 (15/279,763).

Storage device sharing among virtual machines
Veritas Technologies LLC, Santa Clara, CA, has been assigned a patent (10,331,476) developed by Vemuri, Hari Krishna, Pune, India, for a “storage device sharing among virtual machines.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Disclosed herein are various systems, methods, and processes for sharing a storage device with multiple virtual machines. A pseudo-identity is created for a storage device. Information in a hypervisor is configured to modify a response to a command issued to the storage device by a virtual machine. Physical characteristics of the storage device are determined and it is also determined whether the physical characteristics are acceptable. If the physical characteristics are acceptable, a virtual disk associated with the virtual machine is used.

Backup application catalog analyzer
Veritas Technologies LLC, Santa Clara, CA, has been assigned a patent (10,324,893) developed by Telang, Nilesh, Maharashtra, India, for a “backup application catalog analyzer.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The present disclosure provides for analyzing data stored in a data protection storage system to determine a prospective storage scheme that provides a more efficient use of storage resources in the data protection storage system. Data can be analyzed to identify a set of data suitable for long term storage in an archive. Data can be analyzed to identify a set of data suitable for deletion to reduce duplicate copies of data, and remove expired data. Protection policies that provide double coverage of data, causing additional inefficient storage of data, can be identified. A prospective amount of freed storage and other savings can be calculated, if all or part of the prospective storage scheme is implemented, where the prospective amount of freed storage and other savings can be displayed to in a report. A prospective storage scheme may also be determined for a client system that stores live data.”
