I'm sure by now, those of you who are looking at deploying an Office Communications Server 2007 Enterprise Pool realize that a Hardware Load Balancer is REQUIRED. I've been asked by quite a few people if there are good documents out there that lists all compatible devices as well as how to configure them to work with the OCS 2007 Pool. I don't have a list of all the compatible devices, but I did find out about a good document for configuring the Cisco ACE hardware Load balancer!
A good friend of mine (Rui Maximo) on the Unified Communications team has helped with a whitepaper on configuring the Cisco ACE Hardware Load Balancer for an OCS 2007 Enterprise Pool deployment. You can find the article on the Cisco web site:
As I hear about more articles like this for other devices, I'll be sure to let you know about them.
