Nutanix Assigned Four Patents

Architecture for implementing erasure coding
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,672,106) developed by Bronnikov, Dmitri, Foster City, CA, and Gill, Binny Sher, San Jose, CA, for a “architecture for implementing erasure coding.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for implementing erasure coding, including identifying a plurality of storage units, determining a number of storage unit failures to be tolerated, organizing data within the plurality of storage units as a matrix of rows and columns for computing one or more parity data, configuring the matrix to include one or more additional rows having preset values, computing the one or more parity data from the matrix that corresponds to the number of storage unit failures to be tolerated, wherein the one or more parity data comprises a row parity, a first diagonal parity, and a second diagonal parity, wherein the one or more additional rows having the preset values are used to compute the first diagonal parity and the second diagonal parity, and wherein the first diagonal parity comprises a different slope from the second diagonal parity.“

The patent application was filed on December 30, 2014 (14/586,628).

Implementing distributed operations log
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,671,967) developed by Aron, Mohit, Los Altos, CA, and Byrne, Brian, San Jose, CA, for a “method and system for implementing a distributed operations log.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed is an improved approach for implementing a storage system having an operation log where data writes are initially performed to a fast operation log, rather than to its permanent storage location. A distributed operation log can be employed to replicate the data to multiple locations in the storage system.“

The patent application was filed on May 9, 2016 (15/149,618).

Leveraging hypervisor functionality for maintaining application
consistent snapshots in virtualization environment
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,665,386) developed by Bayapuneni, Chaitanya Venkata Krishna, Santa Clara, CA, and Ramachandran, Parthasarathy, Palo Alto, CA, for a “method for leveraging hypervisor functionality for maintaining application consistent snapshots in a virtualization environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for leveraging hypervisor functionality for maintaining application consistent snapshots in a virtualization environment deployed by the hypervisor includes utilizing the hypervisor to generate a hypervisor-specific application consistent snapshot of a virtual machine running in the virtualization environment, taking a storage controller specific application consistent snapshot of the hypervisor-specific application consistent snapshot of the virtual machine, and logically deleting the hypervisor-specific application consistent snapshot.“

The patent application was filed on June 14, 2013 (13/918,660).

Architecture for managing I/O and storage for virtualization
environment with multiple hypervisor types
Nutanix, Inc., San Jose, CA, has been assigned a patent (9,652,265) developed by Narayanasamy, Prakash, Santa Clara, CA, Guturi, Venkata Ranga Radhanikanth, San Jose, CA, Aron, Mohit, Los Altos, CA, Pandey, Dheeraj, San Ramon, CA, and Singh, Ajeet, Cupertino, CA, for a “architecture for managing I/O and storage for a virtualization environment with multiple hypervisor types.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system for managing storage devices, includes a plurality of nodes that implement a virtualization environment, each node of the plurality of nodes comprising a hypervisor, a service virtual machine that sits above the hypervisor, and one or more user virtual machines that sit above the hypervisor, a plurality of storage devices that are accessed by the user virtual machines via the service virtual machines, wherein a first node of the plurality of nodes comprises a first hypervisor, a first service virtual machine and a first set of one or more user virtual machines, wherein a second node of the plurality of nodes comprises a second hypervisor, a second service virtual machine and a second set of one or more user virtual machines, wherein the first hypervisor and the second hypervisor are of different types, and wherein the first virtual machine and the second service virtual machine are of the same type.“

The patent application was filed on March 14, 2013 (13/830,116).
