Cisco Nexus N9K-C9332D-GX2B 32-Port 400GbE QSFP-DD Data Center Switch

The Cisco Nexus N9K-C9332D-GX2B is a compact 1RU fixed-port data center switch designed for modern cloud-scale, AI/ML and hyperscale data center networks. It delivers exceptional throughput, ultra-low latency and 400G density for next-generation spine-leaf architectures.

It provides 32 × 400G QSFP-DD ports for high-density uplink and backbone connectivity. Each port supports breakout options including 2×200G, 4×100G, 4×50G, 4×25G and 4×10G, enabling seamless migration from lower-speed to high-speed networking. It also includes 2 × 1/10G SFP+ ports for management and additional connectivity.

Built on Cisco Silicon One technology, the switch delivers 12.8 Tbps switching capacity and forwarding performance of 5.77 billion packets per second. The last eight ports are capable of wire-rate MACsec and CloudSec encryption, making it ideal for secure data center fabrics and multi-tenant environments.

The N9K-C9332D-GX2B is engineered for high-density networking environments where 400G connectivity, ultra-low latency and high throughput are required.

The N9K-C9332D-GX2B is designed for deployment as a high-density spine or leaf switch in modern data center architectures. Its 32 QSFP-DD ports provide high-speed connections for spine-to-leaf and leaf-to-spine traffic flows.

This architecture enables scalable east-west traffic flows and high-speed interconnection between data center access, leaf and spine layers. The switch supports VXLAN EVPN for modern overlay networking and multi-site deployments.

The N9K-C9332D-GX2B is built on Cisco Silicon One technology, delivering high performance, density and power efficiency for modern data center environments.

The platform provides advanced Layer 2 and Layer 3 capabilities, intelligent buffering with 120 MB shared buffer, and support for high-performance computing, AI/ML workloads and large-scale virtualization.

The N9K-C9332D-GX2B supports VXLAN EVPN fabrics, enabling scalable overlay networking with standards-based control plane protocols.

The platform supports multi-site VXLAN EVPN deployments, allowing organizations to extend network virtualization across data centers with centralized policy and automation.

The N9K-C9332D-GX2B is part of the Cisco Nexus 9000 family and supports Cisco data center networking environments based on Cisco NX-OS.

The platform also supports deployment in Cisco Application Centric Infrastructure (ACI) environments where centralized policy, automation and data center orchestration are required. The switch's default role is leaf, and it can be configured as spine or leaf depending on deployment requirements.

The N9K-C9332D-GX2B supports multiple power-supply configurations designed for redundancy and different airflow requirements.

• Up to 2 power supplies (1+1 redundancy)
• 1500W AC power supply options (port-side intake or exhaust)
• 1100W DC power supply option (port-side intake)
• Port-side intake airflow
• Port-side exhaust airflow
• 6 user-replaceable fan modules (n+1 redundancy)
