Re: Need a new type of anti-trust
I'm aware of Google and AWS designing their own silicon as they are generally moving ahead of the market (i.e. lower power consumption) or in a different direction to the market (i.e. 25Gbps at a time the mainstream market was moving to 40Gbps).
Mellanox is an interesting choice - I would have expected cloud-scale to benefit from cheaper Ethernet (and I acknowledge that Mellanox do provide Ethernet hardware but nothing particularly special when compared to Broadcom/Intel) over Mellanox's specialty of infiniband adapters and switches.
The question is whether infiniband would benefit a cloud-scale data centre - you definitely get improved performance with infiniband (lower latency, performance much closer to PCI-E limits than Ethernet solutions) but at increased cost, reduced availability and the need to convert back to Ethernet at some point which may mitigate any gains.
And I suspect Arista maybe very unhappy losing their main customer...
