Does anyone have a link to more info on their differently sized racks or the storage arrays described in the article? I'm not too familiar with the open compute project, but the storage vault design they have is 2U: http://www.opencompute.org/projects/open-vault-storage/

which doesn't match the article.

Don't have anything to link to, but you're right, everything still ends up in a 2U, technically OU (Open U, 2 inches per OU instead of 1.75), chassis. Each ODM has their own unique sled setup for the server nodes, but everything ends up in a 2OU framework for the busbar connection.
