In one embodiment, a system for managing a virtualization environment includes host machines implementing a virtualization environment, a plurality of clusters of the host machines, a virtualized file server (VFS) comprising a plurality of file server virtual machines (FSVMs), and a VFS cluster manager (CM) configured to distribute storage items among the clusters and receive cluster storage statistics for one or more shares of the VFS. The CM is further configured to, in response to a request from a first FSVM to identify a storage location for a storage item, identify a cluster at which the storage item is to be located based on the cluster storage statistics, identify a second FSVM at which the storage item is to be located based on compute usage statistics of one or more FSVMs in the identified cluster, and send an address of the second FSVM to the first FSVM.

Virtualized file server distribution across clusters

Examples described herein include virtualized file servers which may include cloned instances of the virtualized file server. Cloning a virtualized the 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.

Cloning virtualized file servers

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 virtualized file server backup system configured to identify backup data, wherein the backup data comprises data stored on the virtual disks and VFS configuration information, and the first data is identified in accordance with a backup policy, send the backup data to one or more remote sites for storage, and, in response to detection of changes in the backup data, send the changes to the remote sites in accordance with a replication policy. The backup data may be identified based on a protection domain associated with the backup policy. The data stored on the VFS may include one or more storage objects. The storage objects may include shares, groups of shares, files, or directories.

Virtualized file server disaster recovery

Examples of systems described herein include a virtualized file servers. Examples of virtualized file servers described herein may support disaster recovery of the virtualized file server. Accordingly, examples of virtualized file servers may support metadata fixing procedures to update metadata in a recovery setting. Examples of virtualized file servers may support hypervisor-agnostic disaster recovery.

Disaster recovery for distributed file servers, including metadata fixers

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.

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 first virtualized file server configured to receive a request to access a storage item located at a second virtualized file server, determine that the storage item is designated as being accessible by other virtualized file servers, identify an FSVM of the second virtualized file server at which the storage item is located, and forward the request to the FSVM of the second virtualized file server. The storage item may be designated as being accessible by other virtualized file servers when the storage item is associated with a predetermined tag value indicating that the storage item is shared among virtualized file servers. The predetermined tag value may be stored in a sharding map in association with the storage item.

Virtualized file server data sharing

Examples of systems described herein include a file server virtual machine of a virtualized file server configured to communicate with a user virtual machine over a first virtual network to transfer data and to communicate with a controller virtual machine over a second virtual network to transfer control information.

Configuring network segmentation for a virtualization environment

In one embodiment, a system for managing a virtualization environment comprises a plurality of host machines, one or more virtual disks comprising a plurality of storage devices, a virtualized file server (VFS) comprising a plurality of file server virtual machines (FSVMs), wherein each of the FSVMs is running on one of the host machines, wherein the VFS is configured to detect a failure of one of the FSVMs on a first one of the host machines, wherein the first host machine is located within a first block of host machines. The VFS may then identify a failover path to a second FSVM. For each storage resource associated with the first FSVM, the VFS may migrate the storage resource to the second FSVM.
