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, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.

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.

Abstract: 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.

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: A file server manager disclosed herein accesses information regarding a selected share of a source distributed file server for replication, where the selected share stores at least a portion of a namespace of storage items and is hosted by a first file server virtual machine of the source distributed file server. The file server manager accesses a mapping between virtual machines of the source distributed file server and virtual machines of the destination distributed file server and replicates the selected share to a second file server virtual machine of the destination distributed file server based on the mapping. The file server manager directs a request to read a first storage item to the destination distributed file server and directs a request to write to a second storage item to the source distributed file server while the destination distributed file server services the request to read the first storage item.
