In testing the clustering failover in our own dev network, we discovered a rich feature set to provide for more stability and high availability in clustered environments. The most important to my company will be the multi-site cluster technology.
We have an HA site about 15 miles away with 10Gbps fiber (*1) between them to replicate. With this new technology Microsoft has developed, we can now easily put our HA boxes in another data center. This is a feature we have never been able to have in production for lack of Microsoft's tools to cluster the servers in another site properly.
Now when IBM allows snapshot copy on a block by block level through their 2145 San Volume Controller, we will be in business!! (*2)
