I am very excited about armv8 as existing armv7 single board computers lack the processing power and bus speed to fully support gigabit networking throughput. For example, the BeagleBone advertises "Gigabit ethernet" but can only hit somewhere in the 300-500mbps range due to internal bus limitations. I've heard this is due to lack of good gigabit ethernet chipset support in the existing ARM ecosystem.
The existing products lack physical ethernet ports. Are there any plans to produce a development board with a physical true gigabit port? My ideal board would be one with very minimal graphics (designed for headless use in a data center) and one that focused on fast disk I/O (e.g. USB 3.0, eSATA) and networking (gigabit ethernet).
