DAC 支援 Infiniband？

Notes: 

• 拜訪某間廠商時，廠商說他們的DAC只支援ethernet, 不支援infiniband.
• infiniband 是給 supercomputing 用的協議
• Mellanox DAC cables exceeds the IEEE 802.3bj standard, which means there is a lot of signaling margin left to absorb signal losses and random or burst-mode noise.
• Mellanox 的DAC 要求是1e-15, 比ethernet 1e-12還要嚴格
