Abstract: 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 a backup system configured to, in response to a request to access a data item, determine an access frequency for the data item. 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: A system may include a deployment system configured to receive a request to upgrade a selected virtual machine (VM) of multiple VMs on a plurality of host machines from a first program code version to a second program code version, and, for each host machine, request an upgrade token. When the host machine acquires the upgrade token, the deployment system is configured to generate a snapshot of a code image associated with the second program code version, and provide the snapshot to the host machine via a virtual disk. The snapshot is stored on a storage device associated with a host machine or a server host machine. The snapshot may include metadata identifying a location of the code image on the storage device.

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, one or more virtual disks comprising a plurality of storage devices and accessible by the virtual machine controllers, and a deployment system configured to receive a request to upgrade a virtualized file server on a plurality of host machines from a first program code version to a second program code version, and, for each host machine, request an upgrade token. When the host machine acquires the upgrade token, the deployment system is configured to generate a snapshot of a code image associated with the second program code version, and provide the snapshot to the host machine via the virtual disk. The virtual machine controller located on the host machine stores the snapshot on a storage device associated with the host machine.

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: Examples described herein include virtualized environments including a virtualized file server. Examples of file server virtual machine managers are described which may setup and/or configure file server virtual machines in accordance with a target number of connections and/or a target throughput for the virtualized file server. The virtualized file server may be scaled up, scaled down, scaled in, and/or scaled out.

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.
