My question is about a supported environment (by Vmware) useability, advantages and disadvantages of the following constellation, maybe a recommendation:
Due to changes in the infrastructure between the 6 global (worldwide) sites all locations should get an own Vmware Vcenter Server. The current situation is: 1 VCenter in the Headquarter managing all global ESX Clusters.
The idea of the team-leader: 1 VCenter per Site to reduce network traffic between HQ <-> Site and ease the administration of the Site's IT.
Disadvantages I know so far are:
- 6x Support costs,
- 6x Upgrade/License costs,
- Feature loose,
- Harder to administer / fast checkups by me (HQ)
Advantages I know so far are:
- Reduced network traffic (slow VPN/MPLS lines)
- Availability of DRS / HA during connection problems between Site <-> HQ,
