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.
