Yes, one thing is NetApp’s PN, another thing is what it actually possible… As I mentioned initially, this may be “over the line” support wise, and yes I know all the risks etc. 😊 I think we will keep an eye out for a cheap DS460C which should be the correct replacement (if we can muscle it into the rack) 😊 In fact, the disk PN for the 460C does not match those for 212C (not NetApp’s PN) and this is of cause because of the different caddy used, but yes the disk drives are the same, and are all SAS drives, so I am sure it would work this way.
I am pretty sure I would also be able to use the IOM12 in the 4486, just as you are able to do in the DS4243/4246, which I also doesn’t think is 100% supported, yet it works just fine, so the backplane must be SAS3 compatible all the way from DS4243 I guess 😉

I checked in HWU, there's literally no overlap between the disks you can put into a 4486 and the ones in a 212C.
On the other hand, you should be able to use the suggested DS460C. From what I see, all the disks in a DS212C are also supported in the 460C...
And the offset for the extra cost would be, that you can re-use the IOM12 modules...

Please stop entertaining this idea especially for a production system. It won’t be trouble waiting to happen

As far as I can see on Hardware universe, DS4486 is still supported on 9.12.1 😉
But you are right, if ONTAP wants to control which disks are in which raid groups, it may become an issue… it may make good sense, but when going from an existing setup by moving the disks over will require some planning 😉
Anyway, I think the idea is deal because it looks like only SATA and MSATA is supported in the caddies, and my existing disks are SAS…

Do not do it. That shelf is end of support. It won’t work properly on current ONTAP versions
Disk failures are a pain. ONTAP prevents two disks in the same caddy from being in the same raid group. When a disk does fail it has to fail the serving drives in the caddy and you replaced two at a time

Hi there
Because of space constraints I am planning to move my 3 pcs. DS212C into a DS4486.
But I have a few questions 😊
My existing disks are X318 (8TB NL-SAS), and I think the caddies for the DS4486 are also SAS, so that should technically fit?
Does the NetApp see 24 or 48 disks from the DS4486? Because I plan to reuse existing disks with aggregates on them…
I can see the DS4486 use special PN as spare disks because the caddy has two disks installed. How does NetApp handle the replacement when one disk of the two dies?
I know the healthy disk is also copied to a spare before you can replace the caddy, but do you then replace both disks, or do you just replace the broken disk of the two?
I also have plans on replacing the IOM6 modules with IOM12 just as you can in the DS4246 shelfs.. any issues with that?
I know this is close if not far beyond what is supported 😉
