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.

Abstract: In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, one or more virtual disks comprising a plurality of storage devices, the one or more virtual disks being accessible by the virtual machine controllers, where the virtual machine controllers conduct I/O transactions with the virtual disks, and an upgrade system configured to receive a request to upgrade a virtualized file server on a plurality of host machines from a first program code version to a second program code version, for each host machine, generate a snapshot of a code image associated with the second program code version, and provide the snapshot to the host machine via the virtual disk. The virtual machine controller located on the host machine stores the snapshot on a first storage device associated with the host machine.

Abstract: An example file server manager disclosed herein receives a registration for a distributed file server, where the distributed file server is hosted in a virtualization environment and includes a cluster of file server virtual machines configured to provide access to a file system. The file server manager further synchronizes metadata with the distributed file server, the metadata including identification of each of the file server virtual machines of the cluster of file server virtual machines, the metadata including information regarding the file system and receiving a management request for the distributed file server. The file server manager further formats the management request for the virtualization environment based on the metadata and utilizing information from the registration to access the distributed file server with the formatted management request.

Abstract: An example file server manager provides a user interface for selection of a share of a source distributed file server to be replicated at a destination distributed file server, where the share of the source distributed file server is accessed using a first file server virtual machine at the source distributed file server. The file server manager configures a policy for replication of the share of the source distributed file server to the destination distributed file server based on input received at the user interface and displays, at the user interface, a replication status for the share of the source distributed file server. The replication status indicates that a share of the destination distributed file server corresponding to the share of the source distributed file server has been updated based on a snapshot of the source distributed file server.

Abstract: Examples described herein include virtualized file servers which may include cloned instances of the virtualized file server. Cloning a virtualized file server may allow for testing of new and/or revised features, disaster recovery plans, or other configurations while maintaining availability of the parent (e.g., source) virtualized file server.
