Can anyone help me understand the difference between part - DS224C-0-24-N-C & part DS224C-0-24-C. These parts and their description look exactly the same, the only difference is "-N". I want to understand what this "-N" stands for and what is it used for.

It's a great question. I had to dig in as well. You are absolutely correct, as far as the Shelf enclosure is concerned they are identical. I checked HWU poster and I believe '-N' stands for NSE : NetApp Storage Encryption (NSE), which is NetApp's implementation of full-disk encryption (FDE) using self-encrypting drives.
I guess you have option : You can either go for NSE or Non-NSE drives.
Thank you for your reply, you are partially correct about "N" in a partcode representing NSE(NetApp Storage Encryption), but "-N" seems to be something different. Let me show you with an example.
Part "DS224C-SL-3.8-24N-2P-C" has description "SSD Shelf,12G,24x3.8TB,NSE,2P,-C" which means it has NSE and its represented by "24N".
Part "DS224C-SL-3.8-24N-N-C" has description "SSD Shelf,12G,24x3.8TB,NSE,-C" and this also supports NSE.
Whereas part "DS224C-SL-3.8-24S-N-C" has a description "SSD Shelf,12G,24x3.8TB,-C" which does not support NSE.
So we can infer that "-N" does not represent NSE but something else.
