US EditionCisco unveils 102.4T Silicon One G300 switch chip
- This week, Cisco unveiled the Silicon One G300, a 102.4 Tbps switch chip to appear in Cisco N9000 and Cisco 8000 systems with 64 1.6 Tbps OSFP cages, slated to ship later this year.
- As AI clusters grow, Cisco built a collective networking engine with a shared packet buffer and path-based load balancer to reduce congestion and latency, while P4 programmability extends switch life via software updates.
- The G300 packs 512 ultra-fast 200 Gbps serializers/deserializers , which can aggregate to 1.6 Tbps lanes, supported by 1.6 Tbps pluggable optics breaking out into eight 200 Gbps connections and 800 Gbps linear pluggable optics.
- Datacenter customers can expect roughly a 30 percent reduction in switch power when using Cisco 800 Gbps linear pluggable optics with Cisco N9000 and Cisco 8000 systems, which also achieve 33 percent better link utilization and cut AI training times by up to 28 percent.
- Although the G300 offers 102.4 Tbps, those figures apply to other vendors' silicon as well, and P4 programmability is used by AMD's Pensando NICs and Polara 400; Cisco says it is not making public announcements about copackaged optics.
