This was exactly my train of thought.
I think if we want to have a shot at it the best idea would be to go for a "group buy" thing as we were discussing above and try to negotiate a quantity discount. I would be in if the price would be around 50 - 80 euro shipped (around 80 - 90 USD).
BTW: do you live in Europe?
I do not.
super interesting right? Guesing but looks like 1USB-B, 1 USB-A, 1 reset switch, 1 riser, 1 m.2 nvme, 1 1Gbe, 2xSFP+, 6SATA (III?), and an SFF-8643 (SATA III?) per node in a uATX-ish kind of size - lots of extra standoffs and scale is hard for me to judge - but could work.
I'm not sure about the earlier speculation of stratus-like lock-step execution but thinking there might be some kind of node interconnect going on in that xilinx - probably pcie speed maybe?
though looking at the D-1541 it has an LSI 3008 on it... wondering if that is actually shared between the two nodes and the 8643's are split just for symetric board layout?
anyway if this can be made to work as two separate compute nodes without extra bells and whistles - hey - could be nice little semi-high perf /HA pfsense box with built in 10gbe.
I purchased two OBO to play with and see what happens. Montreal to Denco. Might see these late next week.
acceptance was REALLY fast, offered $200CD each no counter - probably could have offered less.
Mentioned in the offer I was a STH member and was going to try and figure them out.
