vCenter

ESX 4.0
If my vCenter server fails then will ESX hosts (4 of them in a cluster) will continue operating as it should?

What would be the impact of broken vCenter on the existing ESX infrastructure?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, they will continue operating; you can log on to them directly (standalone) if needed to manage your VMs, or via RDP. VMs reside on ESX...vCenter is just a mgmt tool within vSphere.

Hope that helps.

p.s. If your vCenter server fails, certain functions will be inoperational until you get vCenter back up and going -> HA, DRS, VMotion.

coolsport is correct.  If you keep your SQL DB separately on a physical box you can re-install vCenter in matter of minutes on a XP workstaion or another server and reconnect the Database and be back in business

"f your vCenter server fails, certain functions will be inoperational until you get vCenter back up and going -> HA, DRS, VMotion."

----- Does that mean that all hose things won't be operational at all? We do have DRS and vMotion enabled on the servers.

Well, if you need to migrate (VMotion) your VMs, you won't be able to do so seamlessly. You will need to power them down and use a tool like Veeam FastSCP or WinSCP to move them to a different host. vCenter is the source for managing cluster services such as DRS and HA. ESX uses heartbeats to detect if other hosts in the cluster are 'up', and if not, VMotion is used to migrate running VMs to other 'running/operational' hosts in a cluster. If vCenter isn't running, these functions cannot be performed.
