We are currently working to design a DR site with site to site data replication via Oracle products.
CWDM and DWDM seems interesting but I would like to know how does the commucation over these solutions happen. Is it over IP network with IP source/target addressess or something else. What is the protocol used.
Secondly, we are looking for 40Mbps bandwidth over fibre between Active and DR site. Is CWDM/DWDM the right option. Or there could be other options like through plain routing via edge routers between the data center.
Recently i setup replication between 2 datacenters that were about 35 miles apart. We had a DWDM/PtP between them running at 10Gbits total bandwidth. I had a 2Gbit slice of that. the latency of that DWDM and the speed of my connection allowed me to run a simple ISL between the 2 sites. Nothing special required. just built a channel and trunked it. Worked great. Just thought i would share a past experience in case it is in line with what you are trying to do.

Hello,I understand that Contracts in ACI that are enfored by the leafs are stateless ACL. When is an ACI Contract stateful?- as far as I know when using AVS/AVE?- what about when using Kubernetes/Openstack integration with ovs?
