Patent number: 11550559Abstract: A system may include a deployment system configured to receive a request to upgrade a selected virtual machine (VM) of multiple VMs on a plurality of host machines from a first program code version to a second program code version, and, for each host machine, request an upgrade token. When the host machine acquires the upgrade token, the deployment system is configured to generate a snapshot of a code image associated with the second program code version, and provide the snapshot to the host machine via a virtual disk. The snapshot is stored on a storage device associated with a host machine or a server host machine. The snapshot may include metadata identifying a location of the code image on the storage device.Type: GrantFiled: November 18, 2019Date of Patent: January 10, 2023Assignee: Nutanix, Inc.Inventors: Kalpesh Ashok Bafna, Aroosh Sohi, Alexander Michael Bunch

Patent number: 11550558Abstract: In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, one or more virtual disks comprising a plurality of storage devices, the one or more virtual disks being accessible by the virtual machine controllers, where the virtual machine controllers conduct I/O transactions with the virtual disks, and a deployment system configured to receive a request to deploy a virtualized file server on a plurality of host machines, where the request is associated with deployment parameters, select a deployment image for the host machines based on the deployment parameters, and provide the deployment image to each host machine via the virtual disk. The virtual machine controller located on the host machine stores at least a portion of the deployment image on a storage device associated with the host machine.Type: GrantFiled: February 1, 2017Date of Patent: January 10, 2023Assignee: Nutanix, Inc.Inventors: Kalpesh Ashok Bafna, Aroosh Sohi, Alexander Michael Bunch, Venkata Vamsi Krishna Kothuri, Rishabh Sharma, Mausumi Ranasingh

Patent number: 10911225Abstract: An approach for full-path data encryption, where user virtualized computers (e.g., user VMs) are configured to communicate with other virtualized computers or VMs using IPsec protocol encryption standards. The user VMs may send a first encryption or authorization key to the other VMs, which the other VMs may use to authenticate the user VMs and encrypt and decrypt data stored to storage devices using a second encryption key. In some approaches, the other VMs may interpret or decrypt the data sent via IPsec and then perform data optimizations (e.g., compression, deduplication) on the data before decrypting/encrypting with the second key.Type: GrantFiled: June 3, 2016Date of Patent: February 2, 2021Assignee: Nutanix, Inc.Inventors: Alexander Michael Bunch, Miao Cui, Ajay Prakash Kulkarni, Peter Alan Turshmid

Publication number: 20190238323Abstract: Examples described herein may provide local key managers on computing nodes of distributed computing systems. The local key managers may protect secrets (e.g. cryptographic keys) in the distributed system such that risk of compromise is reduced or eliminated. The local key managers may utilize a master key to protect secrets. The master key may be protected by generating multiple key shares using a key sharing technique (e.g., Shamir's secret sharing). The multiple key shares may be stored on different nodes in the distributed computing system. In some examples, secure processors, such as trusted platform modules (TPMs), may be incorporated in computing nodes of distributed computing systems described herein. The secure processor may aid in securely protecting cryptographic keys in the event of disk or node theft, for example.Type: ApplicationFiled: January 31, 2018Publication date: August 1, 2019Applicant: Nutanix, Inc.Inventors: Alexander Michael Bunch, Bala Rama Koteswara Rao Neerumalla
