SQL Strikes Again

I learned today that SQL 2008 will actually not install by default in many multi-site cluster solutions. Why? Well, during the SQL 2008 installation, it runs through a Configuration Checker where one of the tests the environment to ensure that the cluster is configured properly.

SQL 2008 Team – Please Add multi-subnet support!

I was informed that feedback for Microsoft product groups should be done through the http://connect.microsoft.com page.

Most of the folks that I spoke with at TechEd are excited about this new feature and are considering multi-site clusters specifically because of this change. Anyway, at TechEd this year the SQL folks made it publicly known that SQL 2008 will NOT support clusters with nodes running on different subnets. Ouch! This is … Continue reading SQL 2008
