Nexus 9500 Modular Data Center Switch Chassis
Product Description
The Cisco N9K-C9504-B3 is a high-performance modular switch chassis from the Cisco Nexus 9500 Series, engineered for large-scale data centers requiring extreme scalability, redundancy, and fabric-level performance.
Designed for spine, aggregation, and core deployments, the 9504 chassis provides a flexible modular architecture supporting multiple line cards, supervisors, and fabric modules. This enables organizations to scale port density and bandwidth as network demands grow, while maintaining low latency and high reliability.
Supporting Cisco NX-OS and Cisco ACI modes, the platform enables automation, policy-driven networking, and deep telemetry, making it ideal for cloud providers, enterprise data centers, and service-provider infrastructures.
