NVIDIA Mellanox MSX1016X-2BRS SwitchX-2 10GbE 1U Open Ethernet Switch — 64-Port SFP+, Dual PSU, MLNX-OS: This is a 1U Open Ethernet switch built on the SwitchX®-2 ASIC, providing 64 ports of 10GbE over SFP+ in a short-depth chassis. The unit ships with two redundant AC power supplies, MLNX-OS Ethernet firmware, and PSU-side-to-connector-side (P2C) airflow. This is an Ethernet-only switch — it is not InfiniBand-capable and does not support 25GbE, 40GbE, or 100GbE port speeds. This is a refurbished unit.
Engineering Context
The SwitchX-2 ASIC provides 1.28 Tb/s of aggregate bidirectional switching capacity across 64 SFP+ ports with cut-through forwarding and sub-microsecond port-to-port latency. The platform supports hardware DCB (PFC, ETS) and ECN for lossless 10GbE transport, full IEEE 802.1Q VLANs, LAG/MLAG, and the MLNX-OS Ethernet feature set. Dual hot-swap AC PSUs deliver supply redundancy. RoHS6 compliant.
Deployment & Use Cases
Top-of-rack switching for high-density 10GbE server access. RoCE fabrics for distributed storage targets such as Ceph, GlusterFS, and SPDK iSCSI/NVMe-oF over Ethernet. Aggregation for VMware vSphere and KVM virtualization clusters. iSCSI and NFS storage networks where DCB lossless transport is required. Open Ethernet deployments where MLNX-OS is preferred over a vendor-locked NOS.

Compatibility & Hard Constraints
Compatible with SFP+ DAC copper, AOC, and 10GBASE-SR/LR optical transceivers, with auto-negotiation to 1GbE on supported optics. Pairs with ConnectX-3 EN, ConnectX-3 Pro, and ConnectX-4 Lx adapters at 10GbE. Not compatible with 25GbE SFP28, 40GbE QSFP+, or 100GbE QSFP28 optics — the chassis has SFP+ cages only. Not InfiniBand-capable and not field-convertible to InfiniBand. Use matching airflow (P2C) on adjacent rack equipment to avoid hot-aisle recirculation.
