Cohesity, Inc., San Jose, CA, has been assigned a patent (10,503,543) developed by Bhat, Anand, Boggarapu, Anil Kumar, Bangalore, India, and Jagannath, Arvind, San Jose, CA, for “hosting virtual machines on a secondary storage system.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”At least a portion of a virtual machine is hosted on at least one node of a first subset of a plurality of nodes of a secondary storage system. The virtual machine comprises a plurality of portions that can be distributed between the plurality of nodes and is configured into a first state of a plurality of states, such that, in the first state, the plurality of portions is distributed between a first subset of the plurality of nodes and each of the first subset of nodes stores a portion of the virtual machine in its corresponding storage device. A node from the second subset of the plurality of nodes to host the virtual machine in a second state of the plurality of states is selected based on at least one of storage, memory or processing resources of one or more nodes of a second subset of the plurality of nodes.”
The patent application was filed on April 19, 2019 (16/389,201).
Tier-optimized write scheme
Cohesity, Inc., San Jose, CA, has been assigned a patent (10,489,059) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, San Jose, CA, for a “tier-optimized write scheme.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A request to write data corresponding to at least a first portion of a file is received. It is determined whether to perform the request either as an in-place write or as an out-of-place write. Performing the in-place write comprises performing a write to a low latency storage device, and performing the out-of-place write comprises performing a write to a higher latency storage device. The request is performed as either the in-place write or the out-of-place write based on the determination. Performing the request as the in-place write includes writing the data to a first location on a storage tier storing the first portion of the file, and performing the request as the out-of-place write includes writing the data to a second location on one of a plurality of storage tiers of a computing node, other than the first location.”
The patent application was filed on October 8, 2018 (16/154,556).
Backup operations in tree-based distributed file
Cohesity, Inc., San Jose, CA, has been assigned a patent (10,467,216) developed by Aron, Mohit, Los Altos, CA, and Shanmuganathan, Ganesha, Santa Clara, CA, for “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 n 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 n 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 June 23, 2017 (15/632,121).
Establishing persistent connection with remote secondary storage
Cohesity, Inc., San Jose, CA, has been assigned a patent (10,466,933) developed by Bysani Venkata Naga, Suresh, San Jose, CA, Srinivas, Sudhir, Cary, NC, and Gupta, Anubhav, Sunnyvale, CA, for “establishing a persistent connection with a remote secondary storage system.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A first persistent connection pipe is established from a node of a secondary storage system to an access service associated with a cloud service system. A second persistent connection pipe is established from the node of the secondary storage system to the access service. A communication direction role of the second persistent connection pipe is switched to enable the access service to initiate a communication to the node of the secondary storage system via the second persistent pipe.”
The patent application was filed on December 19, 2018 (16/226,366).
