[arm-allstar] the Pi3 is on the way...

[kk6ecm]

I've experienced issues with ACID on the higher priced boards when I install two nodes, with both USB devices on one bus. Placing them on separate buses works best. The RPi 2 shows logical positions of 4 devices in one bus. If the Pi 3 also utilizes a single bus for all devices I'd question the wisdom of trying to put two radio nodes on one RPi3.

Any thoughts on this?

Thanks,
Bob

I can understand the old way of doing things where you had one higher priced PC with hard drives, size, heat, power consumption and you didn't want to create another just to run more nodes but with the cheap small board computers that is not an issue. Most that would want to run more than two nodes are using Allstar to control repeaters and having it all run from one board is not a good way to do it from a redundancy standpoint. If one system goes down you have lost all repeaters or nodes.

The boards and nodes can be Ethernet connected as easily as if they were on the same server. That is the beauty of Allstar, you can have as many "ports" as you want.
