Patent number: 11966729Abstract: In one embodiment, a system for managing communication connections in a virtualization environment includes a plurality of host machines implementing a virtualization environment, wherein each of the host machines includes a hypervisor, at least one user virtual machine (user VM), and a distributed file server that includes file server virtual machines (FSVMs) and associated local storage devices. Each FSVM and associated local storage device are local to a corresponding one of the host machines, and the FSVMs conduct I/O transactions with their associated local storage devices based on I/O requests received from the user VMs. Each of the user VMs on each host machine sends each of its representative I/O requests to an FSVM that is selected by one or more of the FSVMs for each I/O request based on a lookup table that maps a storage item referenced by the I/O request to the selected one of the FSVMs.Type: GrantFiled: January 20, 2022Date of Patent: April 23, 2024Assignee: Nutanix, Inc.Inventors: Richard James Sharpe, Kalpesh Ashok Bafna, Durga Mahesh Arikatla, Shyamsunder Prayagchand Rathi, Satyajit Sanjeev Deshmukh, Vishal Sinha, Anil Kumar Gopalapura Venkatesh, Rashmi Gupta, Rishabh Sharma, Yifeng Huang

Publication number: 20230056217Abstract: An example file server manager updates a selected share of a destination distributed file server based on a snapshot of at least a portion of a selected share of a source distributed file server. The selected share of the destination distributed file server is updated while the source distributed file server serves client requests for storage items of the selected share of the source distributed file server. The file server manager receives a request to failover from the source distributed file server to the destination distributed file server and configures the destination distributed file server to service read and write requests for storage items of the selected share of the destination distributed file server. The file server manager further redirects client requests for storage items of the selected share of the source distributed file server to the destination distributed file server by updating active directory information.Type: ApplicationFiled: January 21, 2022Publication date: February 23, 2023Applicant: NUTANIX, INC.Inventors: Shyamsunder Prayagchand Rathi, Hemanth Thummala, Lakshmana Reddy, Pradeep Thomas, Kalpesh Ashok Bafna, Manoj Premanand Naik
