Comparative Analysis of N-Series Switches
N9550 Switches: N9550 Network switches are spine switches with 400Gb QSFP-DD (Except N9550-32D, each QSFP-DD port also supports 1x 100GbE, or via breakout cables4x 100GbE or 4x 25GbE), providing high-density availability. Built with a reliable Broadcom chipset and hot-swappable redundancies, they are equipped with EVPN-VXLAN and MLAG features through software.
N8550 Switches: N8550 Ethernet switches are ideal for small and medium data centers and large enterprise networks. They are TOR (Top-of-Rack) or leaf switches with 100Gb QSFP28. Each QSFP port is capable of 40Gb or 100Gb for high-density availability and uplink options, or via breakout cables 4x 25G or 4x 10G (Except N8550-24CD8D, which features 24x 200Gb QSFP56 and 8x 400Gb QSFP-DD).
N5850 Switches: N5850 White Box switches are TOR (Top-of-Rack) or leaf switches with flexible 10/100GbE interface speeds (Except N5850-48S6Q, which features 48x 10Gb SFP+ and 6x 40Gb QSFP+).

FS N-Series Bare Metal Switches | Speed | Throughout | Type | Application |
25/100/400GbE interface speeds | Higher throughput compared to the N8550 series. | Spine switches | Data centers | |
10/25/40/100/200/400GbE interface speeds | Higher throughput compared to the N5850 series. | TOR (Top-of-Rack) or leaf switches | Small and medium data centers and large enterprise networks | |
10/100/40GbE interface speeds | High throughput | TOR (Top-of-Rack) or leaf switches | Small data center |
Guidance on Product Selection for Different Applications
At present, the deployment of bare metal switches is mainly concentrated in cloud data center scenarios. Bare metal switches typically play three roles in data centers: the Spine, the Server Leaf, and the Gateway Leaf. These three roles handle different traffic (east or south-north) and require different proportions of hardware resources.
When the bare metal switch is used as a spine switch (N9550 switches), it considers the flow from leaf to leaf and has the characteristics of large capacity and multiple tenants. The server leaf (N8550 switches) switch gathers traffic from the server node and connects to the core of the network, while the gateway leaf (N5850 switches) switches are used for external traffic to the south-north. A bare metal switch with a programmable chip can play various roles, handle different flow forwarding, and provide different functions.
