I am planning the deployment of 2010 with the high availability (HA) in mind. In order to discuss, I list a few questions. HA means max 4 hours downtime. User community: 150-300.
1. How to achieve HA using Exchange built-in features if I have two Exchange 2010 boxes at the same site?
2. What thrid party software can I use to achieve HA if I have two Exchange 2010 boxes at the same site?
3. How can I achieve HA if I have two Exchange boxes at different sites over 3Mbps WAN link?
Is using Exchange built-in features or thrid party solution still feasible over 3Mbps WAN link?
