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: Particular embodiments provide a system for managing a virtualization environment, the system comprising 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, and the host machines form a cluster. A health monitoring service may monitor the FSVMs to determine whether any of the FSVMs has failed or is having problems. If the health monitoring service detects a failure of one of the FSVMs on a first one of the host machines, for each resource lock associated with the first FSVM, the health monitoring service may reassign the resource lock to another one of the FSVMs.
