N1/N2: I think you are making a mistake by concentrating on the advantage of having a single node type. Databases really aren't like other systems.

SuperMicro has a 4 node system available in which each node gets 6 disks, 2028-TP-xx-yyy. Get two of these, populate 2 nodes on each as your databases, and you can grow into the other spaces later. Run your databases on all-SSD; store backups on spinners elsewhere.

Having two node types is not a calamity compared to having just one.

Thanks, I agree that multiple nodes could be acceptable if needed.

So the proposal now is to have one chassis (excluding the backup system) and two types of nodes (normal and database).

Regarding the 2028 please see the conversation in https://news.ycombinator.com/item?id=13153853
