If I am using OS specific or 3rd party clustering services, do i need a shared storage outside the esxi box?
If you are using a 3rd party service, then VMware is not involved Image may be NSFW.
Clik here to view.
For example, using Windows NLB, you can cluster HTTP servers without any special storage requirement. What other requirements exist however will depend on what 3rd party service you choose to use.
edit: What is the point of this requirement? The moment you have a hardware failure, your "fault tolerance" goes down.
