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…

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 😉
