Not sure but I believe you do not want to mix fc and sata loops. Could be wrong though.

clustered sata shelves work just fine. I have several terabytes attached to a 3050 cluster with out any problems. AT-FCX is required for that to work. I'd also recommend being on the latest firmware on the AT-FCX.

One item that I've researching that is a bit unclear, is that, can I can connect a SATA disk shelf (DS14mk2 AT) to a clustered set of FAS960 heads?
I think there is no problem. I assume that you must use the AT-FCx modules, as they are dual-looped. I suspect that the the AT-FCx is mandatory for clustering (as opposed to the AT-FC) , but NOW seems a bit vague, at least according to what I was able to find.
Also, I've heard rumors that connecting SATA shelves to a cluster is not really reliable. I was a bit taken a back, as NetApp as the SATA shelves have been out for a while. Is this really the case?

There is no issue with SATA in a cluster. You are correct that FC and SATA drives need to be on their own loops.

The only area of concern I've seen w/ sata shelves is that firmware upgrades on the AT-FCX mods is disruptive. The disruption is well documented and just needs to be planned when conducting an upgrade.
