The Cisco Nexus 9800 Series chassis architecture can scale from 57 Tbps to 115 Tbps with a combination of various first-generation line cards and fabric modules. Each line card slot in the chassis can support line cards that offer 400GE or 100GE ports now and higher speeds in the future.
The Cisco Nexus 9800 Series Switch line cards and fabric modules are built with power-efficient, high-performance, and high-capacity Cisco ASICs that support dynamic flowlet load balancing, fully shared on-die packet buffering, and line-rate performance for small packets. The Cisco ASIC also has built-in ingress Virtual Output Queueing (VOQ) capabilities that provide the basis for faster job completion times, which is critical for AI/ML fabrics. The ASIC provides these capabilities without compromising on data-center spine/super-spine features, making the Cisco Nexus 9800 Series Switches an optimized platform to build fabrics that can support high-bandwidth applications and compute-intensive AI/ML workloads across data centers of varying sizes and scales.
