Cohesity Assigned Four Patents

Concurrent access and transactions in distributed file system
Cohesity, Inc., Santa Clara, CA, has been assigned a patent (9,870,368) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, Santa Clara, CA, for a “concurrent access and transactions in a distributed file system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments described herein provide techniques for maintaining consistency in a distributed system, (e.g., a distributed secondary storage system). According to one embodiment of the present disclosure, a first set of file system objects included in performing the 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 an inode associated with each identified file system object. Each file system object corresponding to the inode is modified as specified by the update intent in that inode. After modifying the file system object corresponding to the inode, the update intent is removed from that inode.”

The patent application was filed on October 27, 2014 (14/525,018).

Write operations in tree-based distributed file system
Cohesity, Inc., Santa Clara, CA, has been assigned a patent (9,792,309) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, Santa Clara, CA, for a “write 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 August 4, 2014 (14/450,848).

Backup operations in tree-based distributed file system
Cohesity, Inc., Santa Clara, CA, has been assigned a patent (9,720,947) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, Santa Clara, CA, for a “backup operations in a tree-based distributed file system.“
