I started digging in to this yesterday when I had a comment on my Metro Cluster article. I found it very challenging to get through the vSphere Metro Storage Cluster HCL details and decided to write an article about it which might help you as well when designing or implementing a solution like this. First things first, here are the [...]
I had a discussion via email about metro clusters and HA last week and it made me realize that HA’s new architecture (as part of vSphere 5.0) might be confusing to some.
