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 respective 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 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: 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.
