NVIDIA Mellanox® MSX6710-XXX — SX6710 SwitchX-2 36-Port QSFP+ FDR 56Gb/s InfiniBand Switch, 1U
Technical Identity
This listing covers a Mellanox SX6710 — a 1U SwitchX-2 based InfiniBand switch with 36 QSFP+ ports at FDR 56Gb/s per port. The SX67x0 platform provides up to 4Tb/s of non-blocking bandwidth with 200ns port-to-port latency, and managed configurations run MLNX-OS on an onboard x86 dual-core control plane with an integrated subnet manager for fabric bring-up of up to 648 nodes. Protocol: InfiniBand FDR. Condition: Refurbished.
Configuration suffix unknown — read before ordering. The SKU is listed as MSX6710-XXX because the configuration suffix has not been confirmed. On this platform the suffix encodes managed versus unmanaged control plane, power-supply population and airflow direction (catalogue examples include MSX6710-FS2F2 and MSX6710-FB2F2). Those attributes cannot be inferred from the base MSX6710 designation and must be read from the unit label and confirmed with T.E.S before the order is placed. Everything below describes the verified SX6710 platform only.

Engineering Context
FDR InfiniBand carries 14.0625Gb/s per lane over four lanes with 64/66 encoding, producing the 56Gb/s per-port figure quoted for the SX6710. On this platform the managed/unmanaged distinction is material: only the managed build carries the onboard subnet manager and MLNX-OS stack, so an unmanaged unit needs an external SM host somewhere in the fabric. Airflow direction matters equally, because a switch installed against the rack airflow will run hot. Both are encoded in the model suffix, which is why this unit is listed as MSX6710-XXX.
Use Cases

Top-of-rack InfiniBand FDR 56Gb/s fabric for HPC clusters of ConnectX-3 generation nodes.
Storage back-end fabric for FDR-attached parallel file systems.
Cold spare for an installed SX6710 estate, once the suffix is matched to the deployed units.

What This Is NOT

NOT confirmed managed or unmanaged. The control-plane configuration is unknown until the label is read. Do not plan a fabric around an onboard subnet manager without confirming it.
NOT an Ethernet switch and NOT a gateway. The SX6710 is InfiniBand FDR. The InfiniBand-to-Ethernet gateway is the separate SX6710G line (for example MSX6710G-FS2F2).
NOT an EDR, HDR or NDR switch. Maximum per-port rate is FDR 56Gb/s. EDR needs Switch-IB, HDR needs Quantum, NDR needs Quantum-2.
NOT a QSFP28, QSFP56 or OSFP switch. QSFP+ cages only.
NOT BBU-ready. Battery-backup-unit support belongs to the SX6720 (for example MSX6720-FS2F2), a different model.
NOT a chassis/director switch. Fixed 1U system; it does not accept leaf or spine blades.
NOT supplied with QSFP+ transceivers, DAC/AOC cables, rail kits or spare power supplies.

Compatibility & Hard Constraints

Typical fabric endpoints: Mellanox ConnectX-3 and ConnectX-3 Pro FDR 56Gb/s QSFP+ host adapters and OEM-branded equivalents.
Typical cabling: QSFP+ FDR passive copper DAC and FDR active optical cable. Verify cable profile recognition in the switch CLI.
Software: MLNX-OS on managed units; MLNX_OFED or an in-box IB driver stack on hosts. An unmanaged unit requires an external subnet manager such as OpenSM elsewhere in the fabric.
Rack and power: 1U plus rails, standard depth. PSU count and airflow direction must be confirmed from the unit label and matched to the rack cooling plan.
Pre-deployment verification: configuration suffix, managed/unmanaged state, PSU population, airflow direction, firmware / MLNX-OS level, licence state.

Frequently Asked Questions (FAQ)
Q. What is the Mellanox MSX6710 / SX6710?
A 1U SwitchX-2 InfiniBand switch with 36 QSFP+ ports at FDR 56Gb/s per port, up to 4Tb/s non-blocking bandwidth and 200ns port-to-port latency.
Q. Why is this listed as MSX6710-XXX?
Because the configuration suffix has not been confirmed. On the SX6710 the suffix encodes managed versus unmanaged control plane, PSU population and airflow direction. It must be read from the unit label before ordering; T.E.S will confirm it on request.
Q. Does the MSX6710 include a subnet manager?
Managed SX6710 configurations include an onboard subnet manager supporting fabric bring-up for up to 648 nodes. Whether this particular unit is a managed build is exactly what must be confirmed from the label.
Q. What connector does the MSX6710 use?
QSFP+ only, 36 cages at FDR 56Gb/s. QSFP28 (EDR 100Gb/s), QSFP56 (HDR 200Gb/s) and OSFP modules are not compatible with this platform.
Q. Can the MSX6710 run Ethernet?
No. The SX6710 is classified as an InfiniBand FDR switch. The InfiniBand-to-Ethernet gateway function belongs to the separate SX6710G model line.
Q. How does the MSX6710 differ from the MSX6720?
The SX6720 is the battery-backup-unit (BBU) ready member of the same 36-port FDR family. The SX6710 is not BBU-ready. If BBU support is required, the SX6720 part numbers apply.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. The unit is powered up and inspected where test topology is available, with port and management checks, label verification, cosmetic inspection and anti-static packaging. EU stock, global B2B shipping.
Why T.E.S IT-SOLUTIONS
Every unit ships with: (1) power-on and management verification where test topology is available, (2) label, firmware and vendor-data check, (3) cosmetic inspection, (4) anti-static packaging, (5) global B2B shipping from EU stock, (6) technical consultation at no extra cost.
Condition
Condition: Refurbished. Pre-owned enterprise hardware, cleaned, inspected and tested by T.E.S IT-SOLUTIONS. Supplied without NVIDIA warranty or support entitlement. Because the configuration suffix is unconfirmed, T.E.S will verify and photograph the unit label before dispatch on request.
