Publication number: 20200387316Abstract: Techniques for performing compression operations on persistently-stored data blocks during read/write commands. A method embodiment performs in-line data compression operations over data blocks referenced by a caller. The in-line data compression operations are performed during execution of a storage input-output (I/O) command, between the event of receipt of the storage I/O command and the event of returning status of the storage I/O command. The storage I/O operation is associated with at least one data group comprising one or more data blocks that are identified by the caller. Upon receipt of the storage I/O command, one or more compression rules are applied to the data blocks to determine one or more compression parameters, which compression parameters are used to form specific compression operations that are performed over at least a portion of the data group. The status pertaining to the execution of the storage I/O operation is returned to the caller.Type: ApplicationFiled: August 26, 2020Publication date: December 10, 2020Applicant: Nutanix, Inc.Inventors: ChernYih CHEAH, Kiran TATIPARTHI, Manosiz BHATTACHARYYA, Varun Kumar ARORA

Patent number: 10567009Abstract: Dynamic erasure coding for computing and data storage systems. A method embodiment commences upon accessing a set of fault tolerance policy attributes associated with the computing and data storage system. The topology of the system is analyzed to form mappings between the computing nodes of the system and the availability domains of the system. Based on the fault tolerance policy attributes, the topology, and the generated mapping, a plurality of feasible erasure coding configurations are generated. The feasible erasure coding configurations are scored. One or more high-scoring feasible erasure coding configurations are selected and deployed to the computing and data storage system. The method is repeated when there is a change in the fault tolerance policy attributes or in the topology. Depending on the topology and/or the nature of a change in the topology, more than one erasure coding configurations can be deployed onto the computing and data storage system.Type: GrantFiled: December 6, 2017Date of Patent: February 18, 2020Assignee: Nutanix, Inc.Inventors: Minghui Yang, Timothy Sujay Isaacs, Ajaykrishna Raghavan, Dmitri Bronnikov, Jaya Singhvi, Peihong Huang, Varun Kumar Arora

Publication number: 20200037964Abstract: Various embodiments described herein relate to an intelligent warning system in a communication service. One embodiment of the present invention analyzes a user's biometric signals and image data of one of the user's in a communication session to determine a distress level. In addition, location data indicating the user's velocity and direction can be used to determine a distress level. If the biometric signals or the image data indicate a distress level that meets or exceeds a threshold level, a notification is automatically sent to a remote user. This can allow a remote user to render assistance to a user in distress, even when the user is unable to communicate one or more conditions.Type: ApplicationFiled: October 11, 2019Publication date: February 6, 2020Inventors: Rupreet Singh GUJRAL, Varun Kumar PALAVALASA, Noor MAHDI

Publication number: 20200034073Abstract: Systems for high-performance computing. A method operates in a distributed storage cluster platform that has a storage pool and computing nodes that concurrently execute foreground tasks and background tasks. A uses interacts with a user interface to input specifications of background task time windows. Background tasks that run within the time frame of a background task time window are permitted to be scheduled at a relatively higher resource usage rate that consumes relatively higher cluster resources than do background task tasks that run outside of the background task time window. When the background task time window closes, the relatively higher resource usage rate of the running cluster background tasks is reduced to a relatively lower resource usage rate. Background tasks can self-observe the background task time windows and/or can be controlled by messages received from a virtualized controller that is designated to perform cluster-wide observations and to make cluster-wide determinations.Type: ApplicationFiled: May 23, 2016Publication date: January 30, 2020Inventors: Arun SAHA, Varun Kumar ARORA, Vinayak Hindurao KHOT

The storage pool comprises stored information and respective metadata that describes the stored information. Instances of a metadata search engine are installed on the computing nodes such that the metadata search engines have access to both local data stored in the storage pool as well as to networked storage in the storage pool. A user defines metadata management application extensions for extending the metadata search engine using computer programming languages. When executed by the metadata search engine, the extensions perform user-defined functions. A metadata analysis command is associated with the user-defined function and the metadata analysis command is launched from within the metadata search engine to perform the user-defined function over metadata stored in the system.Type: ApplicationFiled: November 30, 2016Publication date: January 30, 2020Applicant: Nutanix, Inc.Inventors: Varun Kumar ARORA, Vinayak Hindurao KHOT
