NVIDIA Mellanox MIS5030Q-1BFC 36-Port 40Gb/s QDR InfiniBand Managed Switch: This is a 1U short-depth, 36-port QSFP managed InfiniBand switch from the IS5000 (InfiniScale-IV) family running at 40Gb/s QDR per port. It includes an embedded Chassis Manager for in-band/out-of-band switch administration and ships with a single power supply and PSU-side to connector-side airflow. This is not the unmanaged MIS5025Q-1BFC variant and is not an FDR or Ethernet platform. This is a refurbished unit, professionally tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MIS5030Q-1BFC delivers up to 2.88 Tb/s of non-blocking switching capacity across 36 QSFP ports at 40Gb/s QDR each on the InfiniScale-IV ASIC, with sub-200ns port-to-port latency typical of the platform. The embedded Chassis Manager exposes CLI and web/SNMP interfaces for configuration, port monitoring, firmware upgrades and diagnostics. Subnet Management can be run on the switch (where supported by firmware/license) or delegated to host-based OpenSM in larger fabrics. The 1U short-depth chassis is RoHS-compliant and suitable for shallow racks.
Deployment & Use Cases
Core or leaf switch in QDR InfiniBand HPC clusters needing on-switch management. Storage cluster interconnect for Lustre, GPFS or NFS-RDMA over QDR. Departmental supercomputing pods. Mixed-vendor fabrics where centralized switch-level monitoring is required. Short-depth telco and edge cabinets where a 1U short-depth managed IB switch is required.

Compatibility & Hard Constraints
Operates in InfiniBand QDR mode only — it does not run FDR 56Gb/s and does not run Ethernet. The embedded Chassis Manager handles switch administration; depending on firmware and licensing, on-switch Subnet Management may or may not be available — for large fabrics use host-based OpenSM. Compatible with NVIDIA Mellanox ConnectX-2 and ConnectX-3 InfiniBand adapters at QDR; FDR-only adapters will negotiate down to QDR. Cabling must be QSFP QDR-rated. Ships with a single PSU; airflow direction is fixed and must match rack cooling. Fan and PSU spares must match the IS5030 SKU family.
