Darn. I was thinking today that I would have a great application for a BBB if it had a second ethernet interface for a separate storage network. Say mount a ceph block device over one ethernet interface and use the other for "business" traffic with no reason to hit the SD or on-board flash at all while it is running. The primary bottleneck in the application I have been investigating so far is disk access. Flash is slow. Network storage is much faster. Separating storage from traffic is even better, particularly when you have only a 100M interface. I have been doing it with vlans but still, the two sorts of traffic compete for interface bandwidth. If I found a genie right now, one of my three wishes would be a dual ethernet BBB.
