I am currently investigating the roll out of network virtualisation using Hyper-V, Windows Server gateway and SCVMM 2012 R2
I have tested deploying a single WSG in a single datacentre and I can get VMs working with Network Virtualisation.
I have a requirement to deploy network virtualisation in multiple datacentres so that I am able to amongst other things live migrate VMs between datacentres with next to no downtime.
My question is what do I need to deploy to make this work?
For example do I need a WSG in each datacentre and if so are they completely independent of one another or are they aware of one another?
I understand that each datacentre will have its own provider address space but I'm assuming the customer VM network will be the same at each datacentre - this would mean the customer VM network gateway IP would be in two locations but does this matter if the provider addresses are different?
Is there anyone who has experience configuring WSG / NVGRE at multiple sites who could give some useful tips?
Thanks
John.
