Veritas Technologies Assigned Six Patents

Performing fencing operations in multi-node distributed storage
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,127,124) developed by Dash, Prasanta R., San Jose, CA, Randhawa, Amarinder Singh, Sunnyvale, CA, Jagtap, Asmita, Pune, India, Yalamanchili, Chaitanya, Santa Clara, CA, and Buddhi, Madhav, Sunnyvale, CA, for “performing fencing operations in multi-node distributed storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Various systems and methods for managing node connectivity in distributed storage systems are disclosed. For example, one method involves detecting a communication fault between two nodes. A first node is configured to communicate input/output, (I/O) requests to the second node as in-flight I/O requests. The second node is configured to communicate locally generated I/O requests and the received I/O requests to storage devices. Once the communication fault is detected, a fencing operation is performed. The fencing operation can include processing some of the received I/O requests by the second node, and rejecting any additional in-flight I/O requests received from the first node.”

The patent application was filed on September 28, 2015 (14/867,516).

Modifying track logs during restore processes
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,127,119) developed by Paulzagade, Sudhakar, Pune, India, Jain, Saurabh, Jabalpur, India, Dalal, Chirag, Pune, India, and Karandikar, Siddharth, Pune, India, for “systems and methods for modifying track logs during restore processes.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosed computer-implemented method for modifying track logs during restore processes may include, (1) identifying a backup application that maintains a track log used to identify changed blocks during backup operations, (2) detecting a restore process launched by the backup application to restore at least one block backed up in a backup image, (3) retrieving, from the backup image, block information about the block being restored by the restore process, and then, (4) recording the block information to the track log during the restore process such that the backup application does not identify the block as changed during a subsequent backup operation due at least in part to the block already being backed up in the backup image. Various other methods, systems, and computer-readable media are also disclosed.”

The patent application was filed on May 21, 2014 (14/283,742).

Operating system installation using logical volumes
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,127,029) developed by Zhang, Hui, Wang, Lin, Sichuan, and He, Jiang, Sichuan, China, for an “operating system installation using logical volumes.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed herein are methods, systems, and processes to support hard drive installation of an operating system from a logical volume partition. An initial volatile memory disk is extracted from an operating system, (OS) installation image. A logical volume binary and shared libraries are added to the extracted initial volatile memory disk and then executed. Executing the logical volume binary and the shared libraries modifies a process performed by an OS installation application. The extracted initial volatile memory disk is then repackaged into a modified initial volatile memory disk.”

The patent application was filed on December 30, 2016 (15/395,154).

Space reservation in storage environment
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,114,754) developed by Pendharkar, Niranjan Sanjiv, and Banerjee, Anindya, Pune, India, for “techniques for space reservation in a storage environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Improved techniques and systems are disclosed for ensuring that physical storage is available for cached allocating writes in a thinly provisioned storage environment. By monitoring the size of the cached allocating writes in the file system cache and taking cache occupancy reduction actions when criteria for cache reduction are fulfilled, caching of allocating writes that do not have a corresponding physical storage allocation can be eliminated or reduced to a user-configurable maximum without disabling caching of allocating writes. Using these techniques, allocating writes may be cached without risk of data loss.”

The patent application was filed on September 30, 2015 (14/871,642).

Automated delivery and identification of virtual drives
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,114,664) developed by Tripathy, Soumya, West Bengal, India, Deshpande, Aditya, Pune, India, Gupte, Amit, and Rahalkar, Mohini, Maharashtra, India, for “systems and methods for automated delivery and identification of virtual drives.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A computer-implemented method for automated delivery and identification of virtual drives may include, 1) creating a drive-template archive that contains a collection of virtual-drive templates, each of which contains a unique burned-in configuration identifier,, 2) receiving, a provision request to provision a virtual drive for a requesting virtual machine,, 3) fulfilling the provision request by, A) creating a copy of an appropriate virtual-drive template that matches the specification of the provision request and, B) providing the copy of the appropriate virtual-drive template to the requesting virtual machine, and, 4) utilizing, at the requesting virtual machine, the copy of the appropriate virtual-drive template in response to determining that the burned-in configuration identifier of the copy of the appropriate virtual-drive template corresponds to a drive configuration that fulfills the provision request. Various other methods, systems, and computer-readable media are also disclosed.”

The patent application was filed on September 21, 2015 (14/859,389).

Storage tier selection for replication and recovery
Veritas Technologies LLC, Mountain View, CA, has been assigned a patent (10,097,634) developed by Gorantla, Hrudil, Guntur, India, Ghosh, Subhadeep, Kolkata, India, Hasbe, Sunil, Shirur Anantpal, India, and Rajaa, Subash, Pune, India, for a “storage tier selection for replication and recovery.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed herein are methods, systems, and processes to select storage tiers for data replication and data recovery. A replication stream is received from a replication appliance that is configured to replicate data to a storage tier of multiple storage tiers. Each storage tier differs from at least one other storage tier in at least one storage characteristic. Portions of the replication stream are identified based on input/output, (I/O) characteristics. The portions are stored in one storage tier other than the storage tier based on the I/O characteristics, and a storage cost associated with each storage tier, where the storage cost associated with each storage tier is based on storage characteristics of each storage tier.”

The patent application was filed on April 29, 2016 (15/142,466).
