Active-Active between two datacenters
We are deploying two BIG-IP LTM 4000 appliances this Friday. One will be at a remote datacenter, the other at my home office datacenter. The DCs are connected via 1 Gbps fiber, and running OTV between the two.
1) The LTM in the RDC will be supporting Exchange 2013 and eventually Lync 2013.
2) The LTM in my home office will be supporting all future load-balancing applications after we remove the ACE4710s; Sharepoint, SAP, etc.
3) Both will be backups for each other if one fails.
My requirements are that the Exchange servers be on a subnet local to the remote DC only, and not put the L3 gateway on the LTMs. All future load-balancing should be scalable.
I'm currently running my BIG-IPs on 11.4.0 HF 6. Can I please get some input as to how I should be designing this? Please let me know if there's additional configuration/info necessary for input.
