Examples of systems described herein include a file server virtual machine of a virtualized file server configured to manage storage of a plurality of storage items. The file server virtual machine including a file system configured to receive an access request directed to a storage item of the plurality of storage items and associated with a user. The file system is further configured to retrieve an access control list having permissions information associated with the storage item, and to cache a permissions profile for the user including all permissions pertaining to the user for the storage item. The file system is further configured to determine whether the access request is permissible based on the cached permissions profile.

Handling permissions for virtualized file servers

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 and conducts I/O transactions with the one or more virtual disks, and a virtualized file server self-healing system configured to identify one or more corrupt units of stored data at one or more levels of a storage hierarchy associated with the storage devices, wherein the levels comprise one or more of file level, filesystem level, and storage level, and when data corruption is detected, cause each FSVM on which at least a portion of the unit of stored data is located to recover the unit of stored data.

Self-healing virtualized file server

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.

Failover and failback of distributed file servers

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

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.

Virtualized file server

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 I/O the selected one of the FSVMs.

Examples described herein include virtualized environments including a virtualized file server. Examples of secure domain join processes are described which may facilitate joining a virtualized file server or portions thereof to a domain. In some examples, the secure domain join process itself, and/or an associated file server virtual machine, may have insufficient credentials to write objects into an active directory. The active directory credentials need not be shared with the file server virtual machine. Rather, in some examples, the secure domain join process may provide a user system with a list of actions to be performed using active directory credentials.

Virtualized server systems and methods including domain joining techniques

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.

Virtualized file server smart data ingestion

Examples of systems described herein include a virtualized file server including a first file server virtual machine and a second file server virtual machine configured to manage a distributed file share of storage items. The second file server virtual machine is configured to manage a particular storage item of the distributed file share of storage items. The first file server virtual machine is configured to, in response to receipt of a referral request for a file share path for the particular storage item from a client, look up a file share path for the particular storage item in a map of at least a portion of the distributed file share of storage items, and provide a referral with the file share path that identifies the second file server virtual machine.

Transparent referrals for distributed file servers

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.

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 and conducts I/O transactions with the one or more virtual disks, and a virtualized file server backup system configured to back up data stored in a VFS located a cluster of host machines to an object store, and retrieve the backed-up data as needed to restore the data in the VFS. The object store may be located in a public cloud. The object store may include a low-cost storage medium within the cluster. An FSVM of the VFS may provide an object store interface to low-cost storage media.
