Trying to decide the best path for our upgrade... right now we have vCenter 5.1 sitting on a separate physical box. I do not like the idea of maintaining another server/hardware. Also we may have a Metro cluster down the road so having the vCenter in the ESXi cluster would be good.
Many VM guys I've spoken with are running vCenter within the environment.
How about you? Thoughts? How are you handling redundancy now that vCenter Heartbeat will be going away?
