Cisco Nexus N9K-C93600CD-GX 36-Port 40/100/400G QSFP Data Center Spine and Leaf Switch

The Cisco Nexus N9K-C93600CD-GX is a high-density 1RU fixed-port data center switch designed for modern cloud, enterprise and hyperscale networking environments. It combines high-speed 40G, 100G and 400G connectivity with advanced switching capabilities for demanding data center architectures.

The switch provides 28 × 40/100G QSFP28 ports together with 8 × 40/100/400G QSFP-DD ports. This port combination allows organizations to deploy the switch in high-bandwidth spine-and-leaf architectures while supporting migration toward next-generation 400G networking.

With up to 12 Tbps of switching bandwidth and approximately 4.0 billion packets per second forwarding performance, the N9K-C93600CD-GX is designed for high-throughput east-west traffic, cloud applications, virtualization, storage and high-performance computing.

The N9K-C93600CD-GX is engineered for data center environments where high throughput, low latency and scalable Ethernet connectivity are critical. Its high-density architecture provides a strong foundation for spine, leaf and aggregation network designs.

The Cisco Nexus N9K-C93600CD-GX is designed to operate as either a spine or leaf switch within modern data center fabrics. Cisco identifies this model for spine-and-leaf deployments, making it suitable for scalable east-west traffic architectures.

Its combination of 40G, 100G and 400G interfaces enables high-bandwidth connections between leaf switches, spine infrastructure, servers, storage systems and other data center networking platforms.

The switch supports breakout configurations that allow high-speed QSFP28 and QSFP-DD interfaces to be divided into multiple lower-speed Ethernet connections where supported. This provides greater flexibility when connecting servers, switches and network devices with different interface speeds.

The N9K-C93600CD-GX is part of the Cisco Nexus 9300-GX family and supports Cisco NX-OS, Cisco's data center operating system designed for automation, management and high-performance network operations.

The platform also supports Cisco Application Centric Infrastructure (ACI). Cisco lists the N9K-C93600CD-GX as supporting both ACI spine and ACI leaf deployments, providing flexibility for modern software-defined data center fabrics.

The N9K-C93600CD-GX combines a compact 1RU chassis with high-density fixed ports, enterprise-class processing and dedicated storage for a reliable data center switching platform.

The N9K-C93600CD-GX supports redundant power and cooling configurations designed for data center environments. Cisco provides multiple power-supply and airflow options to accommodate different rack and installation requirements.

• Redundant power supply configuration options
• 1100W AC power supply options
• 1100W DC power supply options
• 1100W high-voltage AC/DC power supply options
• Port-side intake airflow options
• Port-side exhaust airflow options
• Field-replaceable fan options

The N9K-C93600CD-GX provides extensive forwarding and routing scalability for large data center environments. The platform supports up to 512,000 MAC address entries, up to 4,096 VLANs and up to 16,000 VRF instances according to Cisco's published GX Series specifications.
