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 the selected one of the FSVMs.

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.

Abstract: A file server manager disclosed herein accesses information regarding a selected share of a source distributed file server for replication, where the selected share stores at least a portion of a namespace of storage items and is hosted by a first file server virtual machine of the source distributed file server. The file server manager accesses a mapping between virtual machines of the source distributed file server and virtual machines of the destination distributed file server and replicates the selected share to a second file server virtual machine of the destination distributed file server based on the mapping. The file server manager directs a request to read a first storage item to the destination distributed file server and directs a request to write to a second storage item to the source distributed file server while the destination distributed file server services the request to read the first storage item.

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 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.

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.
