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: 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 file server splitting system configured to split an existing virtualized file server (VFS) into a set of new virtualized file servers (VFSs), the splitting system configured to select one or more existing file server virtual machines (FSVMs) to be removed from the existing VFS. For each existing FSVM, the splitting system is configured to identify an available FSVM that is separate from the existing VFS, provide resources of the existing FSVM to the available FSVM, incorporate the available FSVM into one of the new VFSs, and remove the existing FSVM from the existing VFS. The splitting system may be further configured to re-direct requests to access storage items served by the existing FSVM to the available FSVM.

Abstract: Examples of a virtualized file server that persistently stores file system event data records are described. The virtualized file server may include an audit framework with a connector publisher that is configured to publish the event data records and other information for consumption by other services using a message system. The event data records may include data related to various operations on the file system executed by the VFS. The VFS may persistently store event data records according to a data retention policy and/or until an event data record is consumed by one or more particular services.

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 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.

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: Examples of distributed database systems are described. Multiple computing nodes may be utilized to provide a distributed database system. Each of the multiple computing nodes may cache a portion of the distributed database. The cache may be utilized to service write requests. A computing node servicing a write request may provide a callback to other computing nodes hosting the distributed database. The local cache may be updated responsive to the write request and callbacks issued to the other computing nodes to allow for updates of other local caches. In this manner, a local cache may be updated prior to updating the distributed database as a whole in some examples. While callbacks may be used to update cached data on other nodes, the computing node servicing the write request may not need to receive a callback prior to updating the local cache.

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.
