Virtualized file server distribution across clusters
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.

a virtualized file server cluster manager configured to, in response to a request from the first virtualized file server manager to identify a storage location for a new storage item to be added to the storage items:
identify one of the first computing node cluster or the second computing node cluster at which the new storage item is to be located based on a respective cluster storage statistic;
select a third virtualized file server manager of the cluster of virtualized file server managers to be assigned to manage an I/O transaction associated with the new storage item based on a compute usage statistic, wherein the third virtualized file server manager is hosted on the identified one of the first computing node cluster or the second computing node cluster; and
provide an address of the third virtualized file server manager to the first virtualized file server manager.

8. At least one non-transitory computer-readable storage medium including instructions that when executed by a computing node of one of a first or a second computing node cluster, causes the first or the second computing node cluster to:
manage, via first and second virtualized file server managers (VFSMs) of a cluster of VFSMs hosted on a combination of the first and second computing node clusters, input/output (I/O) transactions directed to first and second storage items, respectively, of a share maintained on virtual disks; and
in response to a request from the first VFSM to identify a storage location for a new storage item to be added to the storage items:
identify one of the first or the second computing node cluster at which the new storage item is to be located based on a respective cluster storage statistic;
select a third VFSM of the cluster of VFSMs to be assigned to manage an I/O transaction associated with the new storage item based on a compute usage statistic, wherein the third VFSW is hosted on the identified one of the first computing node cluster or the second computing node cluster; and
provide an address of the third VFSW to the first VFSW.
9. The at least one non-transitory computer-readable storage medium of claim 8 , further including instructions to receive a request for the compute usage statistic from one of the first or second VFSMs.
10. The at least one non-transitory computer-readable storage medium of claim 9 , further including instructions to designate the first VFSM as a leader virtualized file server manager configured to receive the request for the compute usage statistic.
11. The at least one non-transitory computer-readable storage medium of claim 1 , wherein the cluster storage statistic includes a per-cluster storage usage statistic for the first computing node cluster or the second computing node cluster.
12. The at least one non-transitory computer-readable storage medium of claim 8 , wherein the compute usage statistic includes a processor unit utilization associated with the third VFSM.
13. The at least one non-transitory computer-readable storage medium of claim 12 , further including instructions to select the third VFSM in response to the processor unit utilization associated with the third VFSM being less than a threshold value.
14. The at least one non-transitory computer-readable storage medium of claim 12 , wherein the processor unit utilization associated with the third VFSM is an average percentage of the processor unit utilization over a specified time period.
15. A method, comprising:
managing, via first and second virtualized file server managers of a cluster of virtualized file server managers hosted on a combination of a first computing node cluster and a second computing node cluster, input/output (I/O) transactions directed to first and second storage items, respectively, of a share maintained on virtual disks; and
