You're right, I had asked my HP specialist to confirm that it was ECC, and he had said yes, but when I prompted him again on the distinction between link ECC (protects data in motion) vs true on-die ECC (protects data at rest in RAM, much more important), he admitted it was the former and canceled my order.
I now ordered a Beelink GTR9 Pro, which unlike the Framework has dual 10G Ethernet, not the weird 5G flavor. We'll see how that goes.
Ah, interesting. Did you get a ship date? I do like the idea of dual 10G. It would be nice to see a review on how well the GTR9's cooling works and how quiet it is under full load.
The logistics of this archive are quite crazy; most 2-4U JBODs I worked with hold like 24 or 45 SFF SAS disks.
Standard size (unless things have changed) for 10k sff sas disks seems to be about 1.2TB, so you'd need 544 of these to build a raidz big enough. So we're talking 12 4U jbods, well over a full rack.
I guess I can just hope some rich techie with a volcano lair / private datacenter somewhere is keeping a copy..
Buy a Data60 (60 disk chassis), add 60 drives. Buy a 1U server (2 for redundancy). I'd recommend 5 stripes of 11 drives (55 total) with 5 global spares. Use a RAIDz3 so 8 disks of data per 11 drives.
Total storage should be around 8 * 24 * 5 = 960GB, likely 10% less because of marketing 10^9 bytes instead of 2^30 for drive sizes. Another 10% because ZFS doesn't like to get very full. So something like 777TB usable which easily fits 650TB.
I'd recommend a pair of 2TB NVMe with a high DWPD as a cache.
The disks will cost $18k, the data60 is 4U, and a server to connect it is 1U. If you want more space upgrade to 30TB $550 each) drives or buy another Data60 full of drives.
