Abstract: An example system includes a plurality of FSVMs executing at two or more computing nodes configured to cooperatively manage a distributed VFS and a system manager configured to provide a tag based on a pattern and an action associated with the tag to the plurality of FSVMs. The plurality of FSVMs are further configured to scan files of the VFS to tag files including the pattern and tag and to take the action with respect to files in the VFS having the tag.

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 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.

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: 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.

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.

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.

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.

The backup system is further configured to, in response a request to store a data item, determine a storage tier at which the data item is to be stored in a cloud storage service, wherein the tier is determined based on the access frequency associated with the data item, and store the data item at the determined tier of the cloud storage service.

Abstract: Particular embodiments provide a plurality of host machines, one or more virtual disks comprising a plurality of storage devices, and 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. A distributed health monitoring service (HMS) may be running on each of the host machines running a FSVM. The HMS may monitor the FSVMs to determine whether any of the FSVMs has failed or is having problems. The HMS may detect that a plurality of the FSVMs have failed, wherein the failed FSVMs form a portion of the FSVMs comprising the VFS. For each of the failed FSVMs, the HMS may reassign an IP address corresponding to the failed FSVM to a live one of the FSVMs.
