The switchless -> switched and related switch migration documents have the premise that the procedure is non-disruptive to cluster operations. https://docs.netapp.com/us-en/ontap-systems-switches/index.html   Cluster resiliency for a cluster link or cluster switch failure is built into the design of the ONTAP cluster. Redundant cluster ports Redundant cluster switches LIFs fail over when necessary ... View more

Separating your HDD and SSD shelves in different stack is a performance best practice. That said, with only 2 shelves at play, placing them in the same stack has not significant performance impact. Each controller will have a direct SAS link to each shelf, if you properly cable the stack as multipath-HA (MP-HA). The docs show this configuration. That said, since the FAS8300 has 4 onboard SAS ports, why not future-proof your SAS storage for any future expansion?  Use 2 ports for the DS212C and the other 2 ports for the DS224C. If you need to add either HDD or SSD shelves, you can just hot-add them to the appropriate stack. ... View more

You might find this Discord/NetApp channel thread interesting: https://discord.com/channels/855068651522490400/1397557792574935242 A step-by-step guide is provided by a trusted member. The X4013A NVMe SSDs are self-encrypting drives (SED). The fastest and best way to erase data on them is by using ONTAP "crypto sanitize" techniques (essentially shredding the key that the data was encrypted with). See KB: How to cryptographically sanitize a system with all self-encrypting disks (SEDs) If you are repurposing these drives, I would be careful with 3rd party erasure programs. They tend to screw up the boot sector and drive's block format - you end up potentially bricking the drive from an ONTAP perspective.  I have heard that Blancco software might have some awareness of NetApp's disk formats.     ...

It appears that you did not purchase NetApp-sourced drives. ONTAP requires specific custom formats and drive labeling for it to be considered supported.   As for the panic/disruption you see, see: Bug ID 1185571 - ONTAP disruption occurs when an unsupported hard disk drive (HDD) or solid-state disk (SSD) is detected ...

As the old saying goes... "drives can fail... stuff happens." Keep all of your drive and shelf firmware up-to-date for best reliability and resiliency of your storage subsystem. For internal drives in the AFF A250, you'll want to keep up-to-date with ONTAP (See Support Bulletin SU2) https://mysupport.netapp.com/site/downloads/firmware/disk-drive-firmware https://mysupport.netapp.com/site/downloads/firmware/disk-shelf-firmware   ...

Yes, support for the FAS2552 ended in January 2023. The last ONTAP version to support it was 9.8.   You might get some additional advice about using this hardware for "home lab" use from the NetApp Discord channel.

Are you sure your FAS2820 is 4xSSD + 10xHDD?  It's a 12-drive chassis, so it's really 4xSSD and 8xHDD. Anyway, Fusion is conservative, but it is a good tool to estimate performance at a somewhat granular workload configuration level.   You might get some additional advice from the NetApp Discord channel. I recommended joining it and asking your questions there. https://discord.com/channels/855068651522490400/1062049107096633454 I think there's still headroom in the FAS2820 for another shelf, if you add one. Don't be concerned over RAID group sizes - the RAID-DP maximum of 28 drives is always enforced. You simply create additional RAID groups to add to the aggregate (or just create new aggregates with the new storage, if you want). ... View more
