Arista Runs Barefoot With Tofino Programmable Switch Chips
If Andy Bechtolsheim, the chief technology officer at datacenter switching upstart Arista Networks, wanted to design ASICs to try to take a bigger piece of the switch pie – or more precisely, thought that this was a good idea at all – rest assured, Arista would be spending money engineering its own chips and fighting for capacity at the four remaining foundries that have advanced processes. …
