N9600-64OD, 64-Port Ethernet L3 Data Center Switch, 64 x 800Gb OSFP, Broadcom Chip, Support RoCEv2

The N9600-64OD switch provides 64x 800GbE OSFP ports in the 4U height, and each OSFP port can be configured as 400/800GbE, and it also supports 2x 400GbE or 4x 200GbE or 8x 100GbE via breakout cables. Built with a reliable Broadcom BCM78900 Tomahawk 5 chipset, and equipped with redundant pluggable power supplies and fans, it can provide 102.4 Tbps switching capacity and 20,695 Mpps forwarding rate for data center networks.
The switch supports RoCEv2 network, based on Priority-based Flow Control (PFC), Explicit Congestion Notification (ECN), Global Load Balancin (GLB) and Dynamic Load Balancing (DLB), which ensures low latency and lossless RDMA applications and high-speed computing services. N9600-64OD is a next-generation, high-performance, and high-density fixed switch designed for high-performance computing, distributed storage, big data, and other application scenarios.

Flexible Interface Speeds for Multi-scenario Deployment

The switch is a high-density 64x 800GbE OSFP switch, each OSFP port can be configured as 400/800GbE, and it also supports 2x 400GbE or 4x 200GbE or 8x 100GbE via breakout cables, to meet multi-scenario deployment.

Dual Redundant Power Supplies and Smart Fans

Hardware-level redundancy protection provides an extra layer of protection, ensuring continuous operation even in the face of power supply failures, and improves the reliability of the entire network.

Lossless Ethernet and Zero Packet Loss

RDMA technology reduces CPU burden and effectively lowers link latencies. PFC and ECN enables intelligent data exchange and prevents packet loss, ensuring lossless transmission.

Accelerate Provisioning from Days to Minutes

Simplify duplicate network configuration by automation helpers like Ansible, NETCONF, Python, zero-touch provisioning (ZTP), gRPC and Telemetry, greatly saves daily operation costs and time.
