Patent number: 11954372Abstract: A technique efficiently migrates a live virtual disk (vdisk) across storage containers of a cluster having a plurality of nodes deployed in a virtualization environment. Each node is embodied as a physical computer with hardware resources, such as processor, memory, network and storage resources, that are virtualized to provide support for one or more user virtual machines (UVM) executing on the node. The storage resources include storage devices embodied as a storage pool that is logically segmented into the storage containers configured to store one or more vdisks. The storage containers include a source container having associated storage policies and a destination container having different (new) storage policies.Type: GrantFiled: October 12, 2022Date of Patent: April 9, 2024Assignee: Nutanix, Inc.Inventors: Kiran Tatiparthi, Mukul Sharma, Saibal Kumar Adhya, Sandeep Ashok Ghadage, Swapnil Ingle

Publication number: 20240078198Abstract: In accordance with some aspects of the present disclosure, a non-transitory computer readable medium is disclosed. In some embodiments, the non-transitory computer readable medium includes instructions that, when executed by a processor, cause the processor to receive, from a workload hosted on a host of a cluster, first I/O traffic programmed according to a first I/O traffic protocol supported by a cluster-wide storage fabric exposed to the workload as being hosted on the same host. In some embodiments, the workload is recovered by a hypervisor hosted on the same host. In some embodiments, the non-transitory computer readable medium includes the instructions that, when executed by the processor, cause the processor to adapt the first I/O traffic to generate second I/O traffic programmed according to a second I/O traffic protocol supported by a repository external to the storage fabric and forward the second I/O traffic to the repository.Type: ApplicationFiled: September 15, 2023Publication date: March 7, 2024Applicant: Nutanix, Inc.Inventors: Dezhou Jiang, Kiran Tatiparthi, Monil Devang Shah, Mukul Sharma, Prakash Narayanasamy, Praveen Kumar Padia, Sagi Sai Sruthi, Deepak Narayan

Publication number: 20240004766Abstract: Methods, systems, and computer program products for selection of a witness during virtualization system recovery after a disaster event. A recovery plan is configured to identify a witness that is then used to elect a leader to implement the recovery. Various system, and/or network, and/or component failures and/or various loss of function of components of the virtualization system can trigger initiation of the recovery plan. Based on the particular recovery plan that is invoked upon a determination of a network outage, or component failure or loss of function of a component of the virtualization system, a particular witness corresponding to a subset of entities of the particular recovery plan is selected. The witness is used to elect the leader, and the leader initiates actions of the recovery plan. The implementation of the recovery plan includes consideration of the health of components that would potentially be involved in the recovery actions.Type: ApplicationFiled: May 18, 2023Publication date: January 4, 2024Applicant: Nutanix, Inc.Inventors: Ankush JINDAL, Kiran TATIPARTHI, Sharad MAHESHWARI, Shubham GUPTA, Bharat Kumar BEEDU

Patent number: 11740818Abstract: 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: GrantFiled: August 26, 2020Date of Patent: August 29, 2023Assignee: Nutanix, Inc.Inventors: ChernYih Cheah, Kiran Tatiparthi, Manosiz Bhattacharyya, Varun Kumar Arora

Publication number: 20230244691Abstract: Label-based replication of data between two computing clusters. A replication session is established between a source cluster and a target cluster. After making a data item status inquiry originating from the source cluster, the target cluster assesses its then-current status of the data item. Based at least in part on the target cluster's then-current status of the data item, the source cluster determines that at least a portion of the data item can be streamed from the source cluster to the target cluster. As such, rather than making further inquiries to the target cluster as pertains to constituent contents of the data item, the constituent contents of the data item are sent to the target without incurring the protocol costs of making further inquiries. The target cluster determines its then-current status of the data item based on a data item label taken from an entry of a cluster data manifest.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Applicant: Nutanix, Inc.Inventors: Niranjan Sanjiv PENDHARKAR, Shubham Mangilal Sharma, Kiran TATIPARTHI

Patent number: 11575745Abstract: A dynamic feedback technique improves data replication performance by balancing rates of data retrieval and data transmission of a fragmented virtual disk replicated between nodes of clusters on a local site and a remote site of a disaster recovery environment. Each node is embodied as a physical computer with hardware resources, such as processor, memory, network and storage resources, which are virtualized to provide support for one or more user virtual machines executing on the node. The storage resources include storage devices of an extent store, whereas the network includes a wide area network connecting the local and remote sites. The dynamic feedback technique employs a virtual memory buffer configured to balance the data storage retrieval and network transmission rates at a source of replication based on bandwidth demands of the extent store and network throughput as manifested by an available free space (i.e., emptiness) of the virtual buffer.Type: GrantFiled: February 25, 2021Date of Patent: February 7, 2023Assignee: Nutanix, Inc.Inventors: Kiran Tatiparthi, Niranjan Sanjiv Pendharkar, Shubham Sharma

Publication number: 20220398163Abstract: A high frequency snapshot technique improves data replication in a disaster recovery (DR) environment. A base snapshot is generated from failover data at a primary site and replicated to a placeholder file at a secondary site. Upon commencement of the base snapshot generation and replication, incremental light weight snapshots (LWSs) of the failover data are captured and replicated to the secondary site. A staging file at the secondary site accumulates the replicated LWSs (“high-frequency snapshots”). The staging file is populated with the LWSs in parallel with the replication of the base snapshot at the placeholder file. At a subsequent predetermined time interval, the accumulated LWSs are synthesized to capture a “checkpoint” snapshot by applying and pruning the accumulated LWSs at the staging file. Once the base snapshot is fully replicated, the pruned LWSs are merged to the base snapshot to synchronize the replicated failover data.Type: ApplicationFiled: July 29, 2021Publication date: December 15, 2022Inventors: Angshuman Bezbaruah, Kiran Tatiparthi, Mahesh Venkataramaiah, Pranay Kumar Ega, Praveen Kumar Padia, Ramya Bolla, Sudhir Ravi
