Intel is crowing about their silicon being used in Arista’s 7124SX switch. Note that this is Intel’s switching silicon (from their purchase of Fulcrum not the FPGA.). At Network Field Day, Arista was at pains to avoid discussing their merchant silicon vendors, claiming that they choose the best chipset available at any time.
In short, the silicon doesn’t matter when you are software vendor. That’s directly in the face of Cisco and their “we are a software company not a hardware company” except when they make their own silicon as a “core value”.
Intel Ethernet switching technology is at the heart of this new design. Not only do these 10GbE switches provide extremely low latency, they can maintain this latency while providing advanced L2-L4 forwarding features along with features such as data center bridging (DCB) and server virtualization support
