actually if you look in Navisphere, under physical next to DAE ..it will tell you what you have and page 23 tells you what's supported (NS20 has  CX3-10 backend)   [URL]
Hello, I'm decommissioning a CX-3 and would like to take a tray from that array and install it into a NS20. I was told this will work as long as I have a short style DAE in the CX-3 and as long as the drives are compatible. How do I determine what style DAE's I have in my CX-3?  Thanks.
Move DAE from CX3 to NS20
