vCenter

Hey,

We're planning a new vSphere 6 deployment, and currently looking at our options for vcenter HA.

We will have a number of vCenter servers, so we will be deploying an external PSC.

Does anyone know why in the availability guides, there is no mention of protecting the PSC with FT?  The suggested method is to stick two PSC's behind an HLB.....is there a reason why using FT would be a bad idea?

it's mainly because FT will give you protection against Host failure or vm vmx crash

but it won't be able to protect you when Guest OS fails within your PSC VM, or let's say one of the PSC services fails. in these cases if you have minimum 2 instances of PSC installed in Enhanced linked mode, and they are set behind NLB, it would be best possible protection you get.

Yep, fair enough, understood - I guess an HLB could probe for service availability to provide app-level redundancy.

To be fair, I'm not a massive fan of FT.....even now most of the restrictions have been lifted, hardware and ESX is so reliable these days the likelihood these types of failures is small....

Thanks for your reply.
