No hardware = nothing to fail. For sync channels use cross-over cables if possible. They are cheaper, faster and copper is more reliable then baked silicon

You really need to have sync channels configured using different set of hardware (switches, NICs and cabling) to provide redundancy. Software configuration (subnets, VLANs etc) does not matter at all.

Tiny correction: if your hypervisor of choice is ESX you'd better stick with the DIFFERENT subnets.
