StarWind Software has been a wonderful partner to work with over the last few years. I first started working with the product when it was part of Rocket Division, but it was split off and became its own company several months ago.
I recently did a web cast for StarWind Software, and it was a fun project. They also have had several others do web casts on cluster topics. I highly recommend that everyone visit their site to learn more about clustering and to see how their product works with clustering. I think you will be happy to see it.
