  • Patent number: 11409510
    Abstract: 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 respective 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.

  • Publication number: 20210224233
    Abstract: A virtualized file server (VFS) may include a plurality of file server virtual machines (FSVMs) that cooperatively manage a distributed file share of storage items. A data protocol server implemented by a first FSVM is configured to provide communication between a user device and the VFS responsive to a request from the user device to connect to the VFS. A common layer implemented by the first FSVM includes information management metadata for authorized users of the VFS. A web proxy at the first FSVM presents a user access list of storage items to the user device, where the user access list is based on user information received with the request from the user device to connect to the VFS.

  • Publication number: 20210200641
    Abstract: System and method for implementing parallel Change File Tracking (CFT) between a distributed File Server Virtual Machine (FSVM) system and a scale-out backup system using underlying snapshot technology. The FSVM system executes efficient assignments of backup streams between worker nodes of the backup system and computing nodes of the FSVM system based on the number of available worker nodes at the backup system. The assignment of backup streams allows for parallel processing of incremental backup data based on successive data file snapshots. The parallel incremental backup may, for example, be per node, per share, or per data size across nodes or shares.
