NVIDIA Mellanox® SS-SCORPION3 — 36-Port EDR InfiniBand Managed Switch
Technical Identity
The NVIDIA Mellanox® SS-SCORPION3 is a 36-port EDR 100 Gb/s InfiniBand managed switch built around the Switch-IB / Switch-IB 2 silicon generation. It delivers 7.2 Tb/s of non-blocking bidirectional throughput in a compact 1U chassis, with sub-100 ns port-to-port latency. New, factory-sealed unit supplied by T.E.S IT-SOLUTIONS.
Specifications
- Brand / OEM: NVIDIA Mellanox
- Part Number (MPN): SS-SCORPION3
- Category: Managed InfiniBand Switch (rack-mount)
- Ports: 36 × QSFP28
- Per-port speed: EDR 100 Gb/s InfiniBand (also negotiates down to FDR 56 Gb/s / FDR10 / QDR for back-compat)
- Aggregate switching capacity: 7.2 Tb/s non-blocking
- Port-to-port latency: ≤ 100 ns (cut-through)
- Protocol: InfiniBand only — not an Ethernet switch
- Management: Managed — embedded Subnet Manager (UFM / OpenSM), CLI over console + SSH, SNMP, REST, Web UI (MLNX-OS)
- Form factor: 1U, 19" rack-mount
- Power: Dual hot-swap AC PSUs (1+1 redundant)
- Cooling: Hot-swap fan modules; airflow direction depends on SKU variant (P2C or C2P)
- Condition: New, factory-sealed
What This Is NOT
- NOT an Ethernet switch. This is an InfiniBand-only fabric switch. It will not run Ethernet, RoCE-only deployments, or Spectrum-class Ethernet features.
- NOT an HDR or NDR switch. Per-port speed tops out at EDR 100 Gb/s. For 200 Gb/s HDR use a Quantum (QM87xx / QM97xx HDR) switch; for 400 Gb/s NDR use Quantum-2 (QM97xx NDR / QM9700).
- NOT a NIC or adapter card. Requires rack space, mains power, and host adapters (ConnectX-4 / ConnectX-5 / ConnectX-6 EDR-capable) on the servers.
- NOT bundled with QSFP28 cables, AOC / DAC interconnects, rail kit, or transceivers — sold as a standalone switch.
Compatibility & Constraints
- Host adapters (NICs): Pairs with NVIDIA Mellanox ConnectX-4 (MCX45xx / MCX455A / MCX456A), ConnectX-5 (MCX555A / MCX556A) and ConnectX-6 cards configured in InfiniBand mode at EDR.
- Cabling: Use QSFP28 EDR interconnects — MCP1600-series passive DAC for intra-rack runs, MFA1A00-series AOC for inter-rack, MMA1B00 / MMS1V00 QSFP28 optical transceivers for structured fiber.
- Subnet management: Managed variant runs embedded SM; in larger fabrics use NVIDIA UFM Enterprise / Cyber-AI for centralized fabric management.
- OS / drivers: Compatible hosts must run MLNX_OFED or DOCA-Host (Linux), or NVIDIA WinOF-2 (Windows) at a release that supports EDR.
- Airflow: Verify P2C (port-to-connector) vs C2P (connector-to-port) direction matches your hot-aisle / cold-aisle layout before installing.
- Cross-vendor: Standard IBTA-compliant — interoperates with any IBTA-compliant EDR host adapter and cable.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox SS-SCORPION3?
The SS-SCORPION3 is a 1U, 36-port EDR 100 Gb/s InfiniBand managed switch with QSFP28 cages, 7.2 Tb/s non-blocking capacity and sub-100 ns latency, built on the Switch-IB / Switch-IB 2 generation.
Q. Can the SS-SCORPION3 run Ethernet?
No. This is an InfiniBand-only switch. For Ethernet (RoCE or classic IP) deployments at 100 GbE you need a Spectrum-family switch such as the SN2700.
Q. Which adapters and cables should I pair with it?
ConnectX-4 / ConnectX-5 / ConnectX-6 host adapters in InfiniBand mode, connected with QSFP28 DAC (MCP1600-series), QSFP28 AOC (MFA1A00-series) or QSFP28 optical transceivers (MMA1B00 / MMS1V00) over OM3/OM4 or SMF.
Q. Is a subnet manager included?
Yes. The managed variant runs an embedded Subnet Manager (suitable for small-to-mid fabrics, typically up to ~2k nodes). Larger fabrics should use NVIDIA UFM Enterprise.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
New, factory-sealed unit in original NVIDIA Mellanox packaging. Bench-tested for link establishment, port-by-port traffic validation and cosmetic inspection before shipping. Ships from EU stock with anti-static packaging, multi-currency B2B invoicing and worldwide express options.
Why buy from T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS is a Europe-based NVIDIA Mellanox specialist serving HPC, AI and enterprise data-center procurement teams since 2007. Every switch is identified by MPN, NVIDIA P/N and ASIC generation before it ships, and every customer gets free pre-sale compatibility advice for switch, adapter and cable pairing — direct contact with our engineering team, not a call-center.
