About the Cisco Nexus 9808 Cloud-Scale Modular Chassis
The Cisco Nexus 9808 Cloud-Scale Modular Chassis is an 8-slot, high-density switching platform engineered for hyperscale-class core routing and spine-layer aggregation in next-generation AI data centers and carrier edge networks. Built on Cisco's Cloud-Scale ASIC technology, the 9808 supports 800GbE line cards delivering terabit-scale forwarding capacity within a single chassis footprint. The architecture is purpose-built to handle the east-west traffic explosion driven by large-scale GPU cluster interconnects, distributed AI training workloads, and real-time inferencing pipelines requiring ultra-low latency and deterministic forwarding behavior.
Ideal for
- AI/ML GPU cluster spine interconnect providing non-blocking 800GbE fabric for large-scale distributed training workloads
- Hyperscale enterprise data center core routing with EVPN-VXLAN overlays supporting multi-tenant cloud infrastructure
- Carrier and service provider edge aggregation with full SRv6 and MPLS support for programmable WAN services
- High-frequency financial services trading infrastructure requiring deterministic sub-microsecond latency forwarding
- Disaggregated storage fabric core connecting NVMe-oF and object storage clusters at petabyte scale
- Multi-site data center interconnect serving as a high-capacity DCI gateway with integrated coherent optics support
