Why X-series
Data center networks evolve faster than fixed-function switches can adapt. AI workloads demand new congestion control algorithms. Security requires deeper inspection. Proprietary silicon forces costly refresh cycles just to add features. X-Series changes this equation.
Open Architecture
Drive continuous innovation through fully programmable, software-defined switching. XISA gives you assembly-level access to programmable engines. No vendor lock-in.
Operational efficiency
Reduce infrastructure sprawl with efficient, workload-optimized switching. 40% lower power consumption than incumbent 12.8T switches. Sub-700ns latency.
Future-proof investment
Evolve your network to deliver more performance from your existing investments. UEC-ready for emerging AI networking standards.
Scale seamlessly. Innovate freely.
X2 switch silicon

Why X-Switch architecture
Traditional switches use fixed pipelines that force recirculation for complex operations. X-Switch executes instructions in parallel across programmable micro-engines, maintaining line rate without penalties.
Fixed Pipeline
Serial execution
Recirculation penalties
Limited programmability
Fixed packet budget
X-Switch
Parallel execution
No recirculation needed
