Cohesity Assigned Seven Patents

Integrated hierarchical storage management
Cohesity, Inc., San Jose, CA, has been assigned a patent (11,150,830) developed by Cai, Zheng, Cupertino, CA, Pasikanti, Vijay, Sunnyvale, CA, and Shanmuganathan, Ganesha, San Jose, CA, for an “integrated hierarchical storage management.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “File access statistics associated with a content file are maintained by a file tier agent of a secondary storage system. The content file is accessible via a primary storage system. A target storage tier corresponding to the file access statistics associated with the content file is determined according to one or more policies. At least a portion of data of the content file is migrated to the determined storage tier while accessibility of the content file via the primary storage system is maintained.”

The patent application was filed on August 6, 2019 (16/533,356).

Backup operations in tree-based distributed file
Cohesity, Inc., San Jose, CA, has been assigned a patent (11,144,524) developed by Aron, Mohit, Saratoga, CA, and Shanmuganathan, Ganesha, San Jose, CA, for a “backup operations in a tree-based distributed file system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques for cloning, writing to, and reading from file system metadata. Cloning involves identifying a first set of pointers included in a first root node in a file system metadata tree structure that stores file system metadata in leaf nodes of the tree structure, creating a first copy of the first root node that includes the first set of pointers, creating a second copy of the first root node that includes the first set of pointers, associating the first copy with a first view, and associating the second copy with a second view. Reading generally involves traversing the tree structure towards a target leaf node that contains data to be read. Writing generally involves traversing the tree structure in the same manner, but also creating copies of any nodes to be modified if those nodes are deemed to have a different treeID than a particular root node.”

The patent application was filed on September 25, 2019 (16/582,264).

Large content file optimization
Cohesity, Inc., San Jose, CA, has been assigned a patent (11,074,135) developed by Aron, Mohit, Saratoga, CA, Qiu, Zhihuan, Shanmuganathan, Ganesha, San Jose, CA, Venkatachari, and Malini Mahalakshmi, Santa Clara, CA, for a “large content file optimization.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A size associated with a content file is determined to be greater than a threshold size. Contents of the content file split across a plurality of component files are stored. Metadata, for the content file, is updated to reference a plurality of component file metadata structures for the component files. A node of the metadata is configured to track different sizes of portions of the content file stored in different component files of the plurality of component files. File metadata of the content file is split across the plurality of component file metadata structures and each component file metadata structure of the plurality of component file metadata structures specifies a corresponding structure organizing data components for a corresponding portion of the content file.”

The patent application was filed on November 19, 2019 (16/688,653).

Concurrent access and transactions in distributed file
Cohesity, Inc., San Jose, CA, has been assigned a patent (11,023,425) developed by Aron, Mohit, Saratoga, CA, and Shanmuganathan, Ganesha, San Jose, CA, for “concurrent access and transactions in a distributed file system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “According to one embodiment of the present disclosure, a first set of file system objects included in performing a requested file system operation is identified in response to a request to perform a file system operation. An update intent corresponding to the requested file system operation is inserted into a data structure associated with each identified file system object. Each file system object corresponding to the corresponding data structure is modified as specified by the update intent in that data structure. After modifying the file system object corresponding to the corresponding data structure, the update intent is removed from that data structure.”

The patent application was filed on March 8, 2019 (16/296,707).

Scaling virtualization resource units of applications
Cohesity, Inc., San Jose, CA, has been assigned a patent (11,003,504) developed by Prabhakar, Venkatesh, Saratoga, CA, Jain, Sachin, Fremont, CA, Gupta, Anubhav, Sunnyvale, CA, and Duttagupta, Anirvan, San Jose, CA, for “scaling virtualization resource units of applications.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “System resource utilizations by one or more core functionalities of a data storage system is monitored. A system resource allocation for one or more applications of the data storage system is determined based at least in part on the monitored system resource utilizations. A number of virtualization resource units allocated to at least one of the one or more applications is scaled based at least in part on the determined system resource allocation. The number of virtualization resource units allocated to the at least one of the one or more applications is based on a corresponding ratio associated with the at least one of the one or more applications.”

The patent application was filed on June 28, 2019 (16/456,367).

Making more active use of secondary storage
Cohesity, Inc., San Jose, CA, has been assigned a patent (10,996,875) developed by Aron, Mohit, Saratoga, CA, and Reddy, Vinay, San Jose, CA, for “making more active use of a secondary storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques are disclosed which allow a secondary storage system to provide data to non-production workloads in conjunction with performing data backup and protection tasks. As disclosed, a secondary storage system exposes backup data stored by the secondary storage system to other workloads, such as test and development applications, data analytics, etc. These non-production workloads can run at the same time the secondary storage system provides backup services to a primary storage system. This consolidation eliminates the need for an enterprise to deploy separate storage clusters for analytics, test and development applications, etc. and eliminates unnecessary copies of data.”

The patent application was filed on August 8, 2019 (16/536,148).

Using storage to optimize and maintain metadata associated with plurality of small files
Cohesity, Inc., San Jose, CA, has been assigned a patent (10,949,384) developed by Gupta, Apurv, Bangalore, India, and Duttagupta, Anirvan, San Jose, CA, for “using a storage system to optimize and maintain the metadata associated with a plurality of small files.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A size associated with a first content file is determined to be less than a threshold size. In response to determining that the size associated with the first content file is less than the threshold size, a combined metadata structure is updated at least in part by combining metadata of the first content file with metadata of a second content file in the combined metadata structure. A snapshot tree is updated to reference a first portion of the combined metadata structure corresponding to the first content file and to reference a second portion of the combined metadata structure corresponding to the second content file.”

The patent application was filed on May 30, 2019 (16/426,390).
