I'd like the functionality to create a BMC or management node for the cluster board. The primary features being:
- Each node's console UART connected to something like a pair of FDTI FT4232H USB-4xUART, or exposed via compatible headers for: http://www.ftdichip.com/Products/Modules...2H-56_Mini
- The reset pin for each node connected to a relay or similar, ideally with a controller exposed via an external facing USB device.
- Not sure if its possible with the SOPIN's pinout, but ability to out-of-band flash the SPI on a node.
USB is nice for each of these as for development you can loop it back to the first node on the clusterboard. Then for scaling up, say with 6 clusterboards, you could connected each into a hub, and have a single Pine64-LTS have access too all the UARTs and have remote power cycling ability.
Looking further out, upgrading the embedded switch with a 10GBase-T uplink and some amount of management functionality would be useful. The management functionality would allow SDN like work.
