If you stick with ESXi, yes, you don't have many other choices.
Instead, with KVM and Xen, you can use every supported storage
technology usually available with a standard Linux system.

You are missing that DFS are usually used as backend storage, so their
support is strictly depending on your hypervisor hosts and not on the
VM instances. In other words, you can use MooseFS to run both Linux
and Windows instances, but you need to use KVM/XEN hosts and not ESXi.
