Virtual machine data placement in a virtualized computing environment

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a computing system, causes the processor to perform a method for virtual machine data placement on a distributed storage system accessible by a cluster in a virtualized computing environment, the method comprising the computing system:

• based on location data relating to the cluster, identifying a first fault domain, a second fault domain, and a third fault domain of the distributed storage system;
• selecting a first host with a first storage resource from the first fault domain, a second host with a second storage resource from the second fault domain, and a third host with a third storage resource from the third fault domain;
• and
• placing a first copy of the virtual machine data on the first storage resource, a second copy of the virtual machine data on the second storage resource, and a witness disk on the third storage resource, wherein the witness disk contains metadata that requires less storage space than any of the first copy of the virtual machine data and the second copy of the virtual machine data.

A computing system for virtual machine data placement on a distributed storage system accessible by a cluster in a virtualized computing environment, wherein the computing system comprises:

• a processor;
• and
• a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to:
• based on location data relating to the cluster, identify a first fault domain, a second fault domain, and a third fault domain of the distributed storage system;
