## Key points

- Cisco’s new top-of-rack switch offers 48 100G ports.
- Server consolidation can raise rack traffic despite reducing server numbers.
- Cisco expects AI agents to increase network demand and automation needs.

## Summary

Cisco has introduced a 100G top-of-rack switch as server consolidation puts more computing power, and more network traffic, into each rack. The move matters because organisations replacing older servers with newer processors can reduce their machine count and power use while increasing the volume of data their networks must carry.

The 1U N9348C8D-H2 has 48 100G SFP-DD ports and eight 400G uplinks. Cisco says consolidation from third- or fourth-generation Intel Xeon or AMD Epyc servers to current models can reach a 6:1 ratio, and that the extra capacity may support future growth, including AI agents. The company also argues that networks will need more automation to manage rising traffic and routine tasks.
