Did you ever get this working?
I have the same setup without issues. Actually, I have 3 of these, and two work flawlessly, and the third gives me some disk latency issues, but they all show up as storage to the x3650 hosts.
Even if you have it working, can you let me know - it's nice to have other sources out there to compare notes with
Glad to hear you have it working. Unfortunately I have not been able to get to work. I haven't spent much time on it lately due to the fact we might be getting some newish hand-me-downs for development soon.
