How this unit is built
Built to your work order from a recovered chassis, with refurbished power supplies and fans for the airflow you need, then loaded with compatible firmware and operating system and tested before it ships.
See the production flowNVIDIA Mellanox MSB7510-E2 Switch-IB™ 2 EDR InfiniBand Leaf Blade — 36 QSFP28 Ports at 100Gb/s, Refurbished.
The MSB7510-E2 is a Switch-IB 2 EDR InfiniBand leaf blade for the CS7500-series modular director chassis. It IS a modular line card with 36 QSFP28 ports at 100Gb/s EDR per port. It is NOT a 1U fixed-form switch (for that, see SB7800/SB7700), an Ethernet line card, or a spine blade — installs only as a leaf blade in a compatible Switch-IB 2 director chassis.
Engineering Context. Built on the Switch-IB 2 ASIC family, this leaf blade delivers 36 EDR ports × 100Gb/s = 3.6 Tb/s aggregate bandwidth per blade. Switch-IB 2 supports adaptive routing, congestion control, and SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) for in-network collectives, which accelerates MPI all-reduce and similar collective operations on AI/HPC workloads. Sub-microsecond switching latency typical of Switch-IB 2.
Deployment & Use Cases. Modular EDR fabric expansion in CS7500-family director chassis, HPC clusters running MPI workloads, AI training fabrics that benefit from SHARP collectives, enterprise storage networks running Lustre or GPFS over InfiniBand, and spare-blade inventory for production CS7500 deployments.
Technical Specifications:
Compatibility & Constraints. Installs in CS7500-series Switch-IB 2 director chassis only. Will NOT fit Spectrum Ethernet chassis, Quantum HDR/NDR switches, or fixed 1U form factors such as SB7800/SB7700. Requires a director chassis with management modules and PSUs to function — not a standalone switch. Pair with EDR-capable QSFP28 cables (MCP1600 series DACs or MFA1A00 AOCs).
Frequently Asked Questions (FAQ)
Q. What is the MSB7510-E2?
The MSB7510-E2 is a Switch-IB 2 EDR InfiniBand leaf blade with 36 QSFP28 ports at 100Gb/s, for director-class chassis.
Q. Is it a standalone switch?
No. It is a chassis leaf blade requiring a compatible director chassis, not a standalone rack switch.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MSB7510-E2 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, checks EEPROM/vendor data, before dispatch from EU stock.
Why TES. Each MSB7510-E2 leaf blade is inspected and electrically tested by T.E.S IT-SOLUTIONS before shipment, including port-link validation in a director chassis, with 1–3 business day handling from EU stock.
