NetApp does not have a CFS. They have a single-headed filesystem called WAFL. They used to talk about Spinnaker, but I haven't heard that term in ages. In fact, the last thing I heard about scalable NetApp (ala Spinnaker) was the press release when they bought the company.

If you want a single file served by multiple scalable NAS heads without replication overhead, you have to use the EFS.CG. It is the only product out there that does it.

I found the HP gateway with Google pretty quickly: http://h18006.www1.hp.com/products/storageworks/efs/
