Move DAE from CX3 to NS20

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.
