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
