NVIDIA Mellanox MSN2410-CB2F Spectrum 25GbE/100GbE 1U Ethernet Switch: This is a 1U open Ethernet ToR switch built on the Mellanox Spectrum ASIC with 48 SFP28 ports at 25GbE and 8 QSFP28 ports at 100GbE. It is an Ethernet switch, not an InfiniBand switch, and ships as an Open Ethernet platform compatible with Mellanox MLNX-OS, Cumulus Linux, and other ONIE-based network operating systems. The F suffix denotes forward airflow (connector-to-power). This unit is sold New.
Engineering Context
The MSN2410-CB2F provides 3.2 Tb/s aggregate switching capacity with 2.38 Bpps forwarding rate. The 8 QSFP28 uplinks each support 100GbE or 4x 25GbE breakout, enabling 80 effective server-facing ports plus uplinks in a single 1U. Spectrum ASIC supports VXLAN routing and bridging in hardware, RoCE (RDMA over Converged Ethernet), and full IEEE 1588 PTP. Cut-through latency is approximately 300ns port-to-port at 25GbE. The unit ships with ONIE pre-installed and 1+1 hot-swap PSUs plus N+1 hot-swap fans. Management is via dedicated 1GbE management Ethernet, RJ45 console, and USB.
Deployment & Use Cases
Top-of-Rack switching for 25GbE servers in private cloud, virtualization (VMware NSX, KVM, Hyper-V), and Kubernetes clusters. Storage front-end for NVMe-oF and Ceph deployments using RoCEv2. VXLAN EVPN leaf in spine-leaf data center fabrics. AI/ML training networks where 25GbE is sufficient and 100GbE uplinks are needed for spine connectivity. Edge aggregation in service provider networks supporting 25GbE customer drops.

Compatibility & Hard Constraints
SFP28 ports accept 25GbE, 10GbE, and 1GbE optics and DACs. QSFP28 ports accept 100GbE optics, 100GbE DACs, and 4x25G breakout cables for fanout to SFP28 servers. RoCE v2 and VXLAN routing are supported in hardware. Forward airflow only; do not deploy in cabinets requiring port-to-power airflow. Ethernet only — does not run InfiniBand protocols. ONIE installation is required to load a NOS; the unit does not ship with a default OS license bundled.
