Yeah, Intel managed to incorrectly implement the 2.5GbE standard with the result that if you connected older steppings of their NIC to a standards-compliant device massive packet loss and effective data transfer speeds apparently as low as kilobytes/sec in some cases ensued. The only workaround was to force it to gigabit mode. They took an age to release a stepping that fixed this and I think there may have been other issues too, so a whole bunch of motherboards ended up shipping with 2.5Gb support that was effectively unusable.
- geerlingguy 5y agoTo be honest, multiple vendors have really screwed up 2.5/5/10G implementations—I tried cheaping out with FlyProFiber copper transceivers, and would get a solid 2.3 Gbps one way, with 400-800 Mbps the other way. Turns out there was tons of packet loss, but only in one direction. They worked fine for 10 Gbps, but I had to switch to Mikrotik transceivers for 2.5G connections.
