You’ve surely invested a great deal of time and money in your VMware environment and built highly available ESX clusters. But what guarantees do you have that those cluster will always work and fail-over flawlessly no matter what?
Let’s face it – it is difficult to maintain an impeccable cluster configuration that is aligned with vendor best practices. Not to mention staying in-sync with any changes made in the different IT layers that vSphere HA interfaces with. Unfortunately, even a minor misconfiguration or gap between cluster nodes can keep your system from doing what it was meant to do – provide high availability with successful fail-overs.
