Abstract: 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.

Abstract: 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.

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: Examples of systems described herein may manage durable handles for seamless failover. Durable handles may be stored in a persistent volume group. The persistent volume group may be moved, together with all or a portion of file share data, to another computing node responsive to an indication of a failure event. To accommodate asynchronous write shares, asynchronous write operations may also be provided to the target computing node. The asynchronous write operations may be processed before reconnecting clients to the file share.

Abstract: Examples described herein are generally directed towards generating, allocating, and assigning consistent file server user identifiers (IDs) (also described herein as a global identifier (GID)) domains subscribed to by file server(s) within a distributed file server environment. In operation, a virtualized file server of a distributed file server system may scan for and identify a trusted domain subscribed to by the virtualized file server. The virtualized file server may allocate to the trusted domain a range of file server user IDs. The virtualized file server may store a mapping between local user security identifiers (SIDs) in the trusted domain and a respective file server user IDs within the allocated range. The virtualized file server may provide the mapping to a replication target, such as during a replication, migration, and/or a disaster recovery event.

Abstract: Examples described herein include virtualized file servers which may include load balancing. For example, a recommendation engine may estimate a load associated with each of a plurality of file server virtual machines in a cluster. Based on the load, the recommendation engine may recommend changing ownership of one or more volume groups, scaling up the virtualized file server, scaling down the virtualized file server, scaling in the virtualized file server, scaling out the virtualized file server, or combinations thereof.
