Managing multiple Data Centers | Sites with one vCenter without Enhance Link Mode

Jump to solution

Hello everyone,

I have a design question which I could not find much information on online. Is it possible and supported to have multiple ESXI hosts from numerous office locations/ DCs added to a central vCenter without the use of Enhanced Link Mode?

Requirements / Conditions

Each site ( 4 sites) has 6 to 7 ESXI hosts 6.7

Each site running different subnet

Each site is isolated from each other

Suggestions

1. Open firewall port on each site to communicate to vCenter at Site C as well as adding correct routes in router.

2. Create multiple Datacenter in vCenter and add the host to each perspective cluster according to the site.

3. More than adequate WAN bandwidth between each Office location

Why this design? for potential future growth instead of deploying vCenter for new Office sites /locations just deploy ESXi hosts only and have them talk back to a central vCenter off-site

.

If anyone can share links with design solutions or documents I would appreciate it. I assume that as long as the site that is hosting vCenter can communicate to the other sites for management it should work. Of course, this is having all of your eggs in one basket. designing redundant vCenter I understand and know to do but wasn't sure about support or if the design makes sense.

It is possible, management network should be routed across sites.

Yes its possible and not uncommon at least we have such an environment with ROBOs.

FW and Driver of your NICs. Check that the HCL exactly match your current setup.

Thank you all,  I wish vmware had more documentations on these type of designs.
