Help me with NetApp

[Nipp]

Hi team! I am looking for a storage solution for my updated server. Currently I run a NetApp DS4246 with LSI SAS2308 HBA.
The goal is to have more modern solution. Preferably with SAS12G. Here is what I am trying to figure out:
NetApp product lines:

• The classic - DS4(U)24(Drives) 6(SAS6) all nice and clear
• The newer stuff - DE2(U)12(Drives)C - what's C is for?
• The "what's that" stuff - DE6600. It seems to be SAS6, 4U, 60 drives. Where is this one go? Is it an IBM thingy or is that a different series altogether?

IOM12

• I see ebay listings "NetApp X5720A 111-02850 IOM12 Module 12G SAS DS224C DS460C DS212C DS2246 DS4246". The DS212C does make sense. But the DS4246 doesn't. Does that mean the IOM12 will work in SAS2 enclosures? Or is that just a bad ebay listing?

In general - what is there to be aware of, when buying NetApps? The DS4246 works wonderfully - it takes any drive I can throw at it. There are SAS interposers for cheap. It works with multipath and without it. It even link-aggregated the 2 SAS connections.
Is there anything less wonderful in new-er series? DS212C in particular. Any limitations on drives it takes? SATA? 4Kn?

Thank you!

One more Q: What is a Netapp NAJ-1502? I don't know enough about the NetApp. Sounds like it's a controller. What's it for? Is that a SAN of sorts? Is it useful for homelabbers?

I have 4x of the DE6600's in my rack at home. They are great boxes. If you have the right controller... Im running mine with SFF-8088 ports to a HP head server. They daisy-chain just fine.

The C at the end of a shelf name represents 12gbps, or that the shelf uses IOM12 (12 is C in hexadecimal format).
Shelves that start in DE are Netapp E series hardware. Completely separate and not compatible with FAS/AFF/DS systems. Those use 512bs drives and a different OS than ONTAP.
IOM12's will work in DS2246/DS4246 but they will be limited to 6gbps by the backplane. (NAJ-1001 vs NAJ-1501 chassis)
NAJ-1502 is a part number for a DS212C chassis without any drives, modules or power supplies.
