It was back in 2011 when Supermicro released the 2015TA-HTRF.

It is a 2U rack mount fat twin. It contains hot swap modules with two Atom-based computers. In total, you get 8 Atom computers and 24 2.5 inch hot-swap hard drive bays.

I want to build a Ceph cluster and of all the hardware I have seen this looks like it would be the most cost effective. Since I love buying used hardware this is what I would like to get.

The problem is, it must not have been a big seller. I have been unable to find even a single used unit for sale… I’ll keep watching eBay but do not have very high expectations in finding these 🙁
