Cisco has introduced a new top-of-rack switch designed to handle the increased network demands from modern server processors. The N9348C8D-H2, unveiled last week, is a 1U device featuring 48 100G SFP-DD ports and eight 400G QSFP-DD uplinks. This move comes as server consolidation driven by sixth-generation processors from Intel and AMD is pushing network speeds higher. Kevin Wollenweber, Cisco’s senior vice president for datacenter and internet infrastructure, explained that newer processors with dozens or even hundreds of cores generate significant traffic, necessitating faster network interfaces.
The shift to more efficient sixth-gen chips allows for substantial server consolidation, with ratios as high as 6:1 when moving from older models. While the 100G ports may seem excessive for modest server collections, Wollenweber argued that users will quickly grow into the capacity, especially as agentic AI applications become more prevalent. Cisco anticipates that AI agents will stress both north-south cloud connections and east-west internal traffic, making network upgrades inevitable.
At Cisco Live in Melbourne, the company emphasized that deploying AI agents at scale will require highly automated networks. Cisco’s Canvas agentic operations platform aims to alert network administrators only when their attention is needed, handling routine tasks autonomously. Joe Vaccaro, senior vice president and general manager for Network Platform and Assurance, noted that networking professionals are increasingly trusting AI agents with more complex work over time.
