The 400 Gb/sec Ethernet Upgrade Cycle Finally Begins

[ENTERPRISE]

Quote

It has been a long time coming. Over two years, in fact. But the hyperscalers and cloud builders, and probably some of the backbones of telcos and other service providers, are finally getting prepared to make the jump to 400 Gb/sec Ethernet.

 

Arista Networks, the upstart that made a lot of noise in datacenter switching and put the hurt on Cisco Systems in a way that Juniper Networks really can’t anymore, has positioned itself with a move into routing and into campus networks as it bided its time on 400 Gb/sec switching, and is coming into its own in datacenter interconnects, or DCI, just as the 400 Gb/sec cycle is starting to move in earnest. We will see how much market share the company can eat and how much new ground it can break.

is there any drive/ram disk that can even read data that fast?

I wouldn't think singular. Cumulatively.
