This post talk about how to implement a High Availability OCSP Configuration. There’re two major pieces in implementing the High Availability Configuration. The first step’s to add the OCSP Responders to what’s called an Array. When OCSP Responders’re configured in an Array, the configuration of the OCSP responders can be easily maintained, so that all Responders in the Array’ve the same configuration. The configuration of the Array Controller’s used as the baseline configuration that’s then applied to other members of the Array. The second piece’s to load balance the OCSP Responders. Load balancing of the OCSP responders’s what actually provides fault tolerance. I am going to demonstrate using the built in Windows Network Load Balancing feature of Windows Server 2008. You can of course use a third party hardware load balancer if you wish. In this example, we are going to deploy two OCSP Servers in a highly available configuration.
