Looks like they'll be run like Avalon4 and Avalon6 were, where multiple modules are chained together to a single RPi controller. The single-point failure part isn't so great, but since it's an off-the-shelf part replacement is super easy. Setup and configuration are also super easy because you don't have to track down IPs for every individual machine. Overall a pretty good setup.

Thanks Sidehack,

These look like they would sit nicely mounted to a rack shelf with a IBM 2880w PSU on top powering the three. really excited about these
