I'm setting up a small business with 2 serverrooms and one rack per serveroom. The rooms are close together and theres 10G fibre between them.
I would like to have two nodes in each serverroom for a total of 4 ESXi hosts.
We are looking at All-flash vSAN with dedub and compression. Around 8TB of data (before dedub and comp.) and around 40VMs.
VM's in room A should have the copy in room B and vice versa.
Problem is I need Fault domain to control this, but as far as I can tell from the documentation, the requirement is 3 rooms (fault domains) as a minimum?
Hope someone can help point me in the right direction with this setup.
Thanks in advance.
Thankyou for the answer.
Do you know if it is possible to control in what fault domains a particular VM will be located?
In Cormac's example I would like VMs from FD1 and FD2 to be replicated to FD3.
Can a policy be created to steer the VM's in this way?
How about the ROBO feature. Maybe I can create two ROBO enviroments and replicate between them.
