Cisco unveiled six new router and switch chips today as part of its Silicon One initiative announced last year.
The 7-nanometer Q200, Q201, and Q202 routing chips and their L-series switching counterparts span the gamut from 12.8 Tb/s at the high end down to 3.2 Tb/s of routing or switching capacity at the low end.
“The Cisco Silicon One portfolio now covers the entire space from service provider and web-scale routers all the way to the top of rack switches and everything in between,” wrote Eyal Dagan, SVP of Cisco’s common hardware group, in a blog post.
Cisco’s latest silicon consolidates all the switch or routing silicon into a single die. This means that a router only requires a single chip, whereas the competition may require as many as 10, the company claims.
Additionally, Cisco’s flagship Q200 and Q200L chips share a common footprint. The company claims this means customers can design a 32-port 400 Gb/s appliance that can serve routing or switching duties depending on which chip is used.
While Cisco went after the high-end market with the 12.8 Tb/s Q200, its slower siblings still have a role to play, explained Dagan.
“Although the leading switching devices are at rates of 12.8 Tb/s — and soon 25.6 Tb/s — we found that many customers are searching for highly efficient 3.2 Tb/s and 6.4 Tb/s [chips] to play different roles in their network,” he wrote.
And since all of the chips are built around a unified software stack, it means “customers can port one SDK [software development kit] to address multiple markets, while network operators only have to train their support staff once to troubleshoot one architecture across their entire network,” wrote Dagan.
More to Come
While he didn’t give any specifics, Dagan hinted that Cisco will continue to roll out additional silicon at a rapid pace. “Most silicon vendors announce new silicon once every few years, whereas today, we’re announcing six new devices in less than a year,” he wrote.
Chipmakers Innovium and Broadcom have each announced 25.6 Tb/s-capable switching hardware in recent months, however, it remains unclear whether Cisco’s next addition to the Silicon One portfolio will directly address this competition.
