DR - F5, Exchange 2010 and SharePoint 2013 recommendations

Hi Guys,

We are in the middle of implementing DR. We are using Veeam as our product to replicate but also using inbuilt application layer clustering where possible. For most of our applications, we will rely on Veeam to do its business to replicate to a site with the exact same vlans, subnets available (stretched vlans). Our only issue now is F5, exchange 2010 and sharepoint.

Q1. Our current F5 configuration is 2 x virtual appliances (active / standby) in Site A. The P2P link between site A and Site B is 1Gbps. We want to know if its possible to move the standby appliance over to Site B (for DR purposes).

Q2. Exchange 2010, we have 2 X CAS and 2 x MBX servers in Site A. The 2 x CAS go through the F5 to load balance sessions. If Q1 (above) is possible, can we just replicate the 2 x CAS using Veeam and physically move the passive MBX server to Site B? So if DR was to kick in, we would make the F5 active in Site B, bring up the 2 x CAS replicas and make the MBX server in Site B active?

Q3. SharePoint 2013, we have 2 x Web front ends (going through F5 load balancing), 2 x application servers and 2 x SQL servers. Assuming Q1 is possible, can I replicate web front ends and application servers to Site B using Veeam, but physical move the passive SQL node to Site B? If DR was to occur, we bring up the F5 in Site B, bring up the 2 x web front ends, 2 x application servers and make SQL node active in Site B?

Please let me know what other options I have. We are a 250 staff company so we don't want to over kill the infrastructure either.

Thanks guys.

Do you think this would work for the DR site (Site B):

F5 – No F5
EXCHANGE – 1 CAS (replication from Site A) and add an additional MBX server to the DAG but living in Site B for DR purposes (fail over when in DR mode).
SHAREPOINT – 1 FRONT END (replication from Site A), 1 APPLICATION SERVER (replication from Site A) and 1 SQL server (mirroring from Site A)
