- Do Hosts in separate vCenter Clusters need Management Network access to Hosts being managed by another Cluster which is managed by a different vCenter Server?
- Do Hosts in separate vCenter Clusters need Network access to a vCenter Server which manages a different cluster?
Configuration:
- Hosts are all running ESXi 5.5
Primary Site with Production VMs:
- 4 Hosts with Management Network rules for allowing communication with Primary Site vCenter Server
- Primary Site vCenter server network rules for allowing communication with DR Site vCenter Server
- vCenter Datacenter: Main
- vCenter Cluster: Production
- Backups are done using VEEAM to local NAS and then a replica to DR Site
DR Site with only a few VMs running in Production for Active Directory & VEEAM Proxy:
- 2 Hosts with Management Network rules for allowing communication with DR Site vCenter server
- DR Site vCenter server network rules for allowing communication with Primary Site vCenter server
- vCenter Datacenter: Main
- vCenter Cluster: DR
I'm replacing our current router/firewall devices at each and noticed a rule setup to allow communication that I was not thinking was necessary.
- Allowing Hosts @ Primary Site to communicate with Hosts @ DR Site
- Allowing Hosts @ Primary Site to communicate with DR Site vCenter Server
- Allowing Hosts @ DR Site to communicate with Production Site vCenter Server
I have tried searching through the VMware Whitepapers and User Guides but I'm not seeing too many examples of multiple sites to learn from.
Thx!
