Most of our clients with VMware infrastructure. We never heard anything going/went wrong with that infrastructure other than in-house tech ask us ,How to do ? What to do ? etc . In my past two years, i have not seen a failure/down time. They have been running without a single point failure.
I was asked to document for DR. I have no idea what can go wrong !. Experts out there, Can you please list me few things can go wrong with VMware and bring the infrastructure down. Of course ,core switch can bring entire network down , but it is not VMware admin job.
