I talked to Syba USA two months ago and they said end of Q1 so I didn't pursue the idea of bringing 500 into the US and sell them. I still might. Do you know any good platforms for this sort of thing?
Unfortunately, I don't know 500 people who'd want one and I think shipping from the US to anywhere not-US (say, Australia) would be prohibitively expensive.
Chelsio and mellanox both have 100G with good reputations. 10G is not really something we should be comparing on anymore since it's been out over a decade.
Mellanox has 40GbE (and above) adapters with good reputation.
Mellanox also have 10GbE stuff, but that's mostly older generation / legacy (low end). Not sure how the 10GbE ones are regarded.
