So many blogs, so little time, yet this one caught my eye this morning, from the windows Server Division WebLog. Checkout the Clustering updates and hyper-v migration as standard in R2. Something to keep an eye on is the reviewers guide www.microsoft.com/windowsserver2008r2 which will be updated regularly as features are released.
This space is seriously exciting at the moment since this means more clustering features, better cluster management and if you've been reading my blog, you know I'm excited about Hyper-V's lower barrier to entry that vmware when it comes to small shops starting on the virtualization path.
The other side of the coin of course is better clustering for exchange, now THAT'S worth getting excited about! Please do support the beta efforts of R2 as they are released, we all need as good a product as we can get!
