NVIDIA Mellanox MSX1036B-2SFS SwitchX-2 36-Port 40GbE QSFP+ Open Ethernet Managed Switch, 1U: This is a 1U managed Open Ethernet switch built on the SwitchX-2 ASIC, with 36 non-blocking QSFP+ ports running at 40GbE per port. The switch supports MLNX-OS / Onyx for management. This is an Ethernet-mode switch from the SX1036 family, not an InfiniBand-only unit; it does not run as an IB switch in default Ethernet firmware. This is a refurbished unit.
Engineering Context
The MSX1036B-2SFS delivers up to 2.88 Tb/s of non-blocking switching capacity across 36 QSFP+ ports at 40GbE. Each QSFP+ port can be split into 4 x 10GbE lanes via breakout cables, yielding up to 64 usable 10GbE ports plus 8 remaining 40GbE ports in mixed configurations. Port-to-port latency is approximately 250 nanoseconds. The 2-PSU SKU (suffix 2S) provides power redundancy through dual hot-swappable AC units, suitable for production deployments.
Deployment & Use Cases
Top-of-Rack 40GbE aggregation in cloud data centers and OpenStack deployments. Spine-leaf Ethernet fabrics where 40GbE uplinks aggregate 10GbE server access. VMware vSAN ready-node interconnects requiring high-throughput Ethernet between hyperconverged hosts. Hadoop or Spark cluster fabric where east-west 40GbE traffic between worker nodes is the bottleneck.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox ConnectX-3 EN, ConnectX-3 Pro EN, ConnectX-4 Lx, and ConnectX-5 Ethernet adapters at 10GbE or 40GbE. Compatible with QSFP+ direct-attach copper (DAC), active optical cables (AOC), and SR4/LR4 transceivers. This is an Ethernet switch — does not run InfiniBand traffic in default firmware (separate IB images exist for the SX series but are not the default for this SKU). Does not support 100GbE per port; for 100GbE deployments use the SN2700 or SN3700. Breakout to 4x10GbE consumes one QSFP+ port per fan-out cable.
Why Choose T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS validates all 36 ports at 40GbE under load, tests breakout functionality on representative ports, confirms both PSUs are healthy under hot-swap, and verifies MLNX-OS / Onyx boots cleanly before shipment.
