Easiest thing I have done this spring.... Kemp Load Balancer
I have to say, setting up a Kemp Load Balancer to front-end 2 Exchange 2010 servers was just about the easiest thing I have done this year. Set up the hardware, registered the device with Kemp, loaded up an Exchange 2010 template, and configured the two virtual servers. First time I had done this. It took a a bit more than hour from the time we pulled it out of the box until the it was done. Nice!
