Configuring DAG Mailboxes Exchange 2010 with a Remote Site for Disaster Recovery

I am planning an Exchange 2010 DAG setup for Mailbox Databases with a Disaster Recovery ability.

We have 2 locations that are connected via a 100Mb Fibre VLAN provided by our ISP.

Site 1 Main Office all users,     Site 2    Warehouse no local users

Plan is to have (2) Exchange 2010 servers in Site 1 both with CAS, HUB and Mailbox roles (EX1, EX2) and 1 Exchange 2010 server in Site 2 with CAS, HUB and Mailbox Roles (EX3).

EX 1 will have a Mailbox database with DAG to EX2 and 3rd priority to EX3.
EX 2 will have a Mailbox database with DAG to EX1 and 3rd priority to EX3.

Exchange 2010 CAS Array including EX1, EX2 and EX3.

Outlook will point to a Network Load balancer (kemp or Baracuda).

Any thoughts or suggestions on this configuration would be appreciated.

Thanks

Update the plan to look like this?

We have 2 locations that are connected via a 100Mb Fibre VLAN provided by our ISP.

Site 1 Main Office all users,     Site 2    Warehouse no local users

Purpose of equipment in Site 2 is strictly to recover quickly from a disaster at Site 1.

Plan is to have (2) Exchange 2010 servers in Site 1 both with CAS, HUB and Mailbox roles (EX1, EX2) and 1 Exchange 2010 server in Site 2 with CAS, HUB and Mailbox Roles (EX3).

 EX 1 will have a Mailbox database with DAG to EX2 and 3rd priority to EX3.
 EX 2 will have a Mailbox database with DAG to EX1 and 3rd priority to EX3.

Enable DAC on the DAG
Configure Alternate File Share Witness on Secondary DC in Site 2

 Exchange 2010 CAS Array including EX1, EX2   cas.domain.local

cas.domain.local points to VIP on Load Balance Appliance.

Thanks
