New & Refurbished InfiniBand & Ethernet Switches

TES-IT recommends Quantum HDR InfiniBand switches such as MQM8700-HS2F for 200Gb/s GPU clusters and MQM8790-HS2F for 400Gb/s NDR fabrics. These provide ultra-low latency and high bandwidth, ideal for all-reduce operations in AI and HPC workloads.

Yes. TES-IT supplies Spectrum-2 (MSN2700, MSN3700) and Spectrum-3 (MSN4700, MSN4600) Ethernet switches, certified for cloud and enterprise workloads. They deliver line-rate performance with features like VXLAN, RoCE v2, and advanced telemetry, ensuring reliable data center operations.

TES-IT maintains a large inventory of Mellanox Spectrum and Quantum switches in Europe, the USA, and APAC. Most orders ship the same day with 24–72h delivery to major data center hubs, avoiding OEM lead times of 8–12 weeks.

Yes. All TES-IT refurbished switches undergo a rigorous 12-step certification process, which includes firmware updates, burn-in testing, and throughput validation. Each unit is covered by a 3-month warranty with RMA, advanced replacement, and 24/7 technical support.

Cloud operators typically deploy Spectrum-3 MSN4700 series for 200/400GbE Ethernet fabrics and Quantum-2 MQM8790 for InfiniBand NDR clusters. TES-IT can pre-bundle these switches with matching ConnectX-6/7 NICs and cables for turnkey deployments.

Yes. Telecoms and ISPs use Spectrum-2 and Spectrum-3 switches for 5G and edge deployments thanks to their scalable bandwidth, low latency, and programmability. TES-IT supplies refurbished units at up to 70% cost savings, ensuring faster rollouts.

Every switch is tested with full port burn-in, protocol validation (Ethernet, InfiniBand, RoCE), environmental stress checks, and firmware updates to the latest stable MLNX-OS/Onyx. Only switches passing all tests are shipped to customers.

Yes. TES-IT can deliver switches with pre-loaded firmware, VLANs, InfiniBand fabric configs, or RoCE v2 enablement, based on your requirements. This saves IT teams valuable setup time and ensures plug-and-play deployment.

Yes. Refurbished MQM8700-HS2F Quantum HDR switches from TES-IT deliver 200Gb/s InfiniBand at up to 65% lower cost than OEM pricing. This helps universities expand AI/ML clusters without waiting 12 weeks for OEM lead times, while staying within grant budgets.

Cloud providers often deploy MSN4600 series Spectrum-3 for scalable 400GbE fabrics and MQM8790 Quantum-2 NDR for 400Gb/s InfiniBand. These support massive east-west traffic patterns and all-reduce operations, enabling efficient AI training at scale.

Yes. Spectrum switches fully support RoCE v2 (RDMA over Converged Ethernet), which enables low-latency, high-throughput connectivity for NVMe-oF storage and AI acceleration. TES-IT pre-tests each switch for RoCE v2 readiness.

Yes. Many telecom operators use MSN2700 and MSN3700 Spectrum-2 switches for 5G edge nodes. Their high throughput, low latency, and programmability make them ideal for distributed architectures. TES-IT supplies these globally with same-day shipping.

TES-IT applies a 12-step certification process: 72h burn-in, firmware upgrades, port-by-port throughput testing, and interoperability checks with ConnectX NICs. This ensures refurbished Spectrum and Quantum switches perform identically to new hardware in HPC workloads.

Yes. Mellanox adapters (ConnectX VPI) and switches can operate in both Ethernet and InfiniBand modes. TES-IT can deliver switches pre-configured for the required fabric, enabling universities and enterprises to run hybrid environments.

Yes. Spectrum switches are known for low power per Gb/s compared to competitors. By using refurbished Mellanox Spectrum-3 switches (e.g., MSN4700), enterprises reduce both CapEx (70% savings) and OpEx (lower energy use).

Yes. TES-IT supplies full turnkey bundles including Spectrum/Quantum switches, ConnectX NICs, and DAC/AOC cabling. Bundles are pre-tested for compatibility, reducing deployment time for HPC labs, universities, and cloud providers.
