Description

The NVIDIA Mellanox MSB7570-E is a Switch-IB 2 spine blade module — an EDR 100Gb/s InfiniBand switching blade designed to populate Mellanox modular director chassis. This is NOT a fixed pizza-box switch and NOT a leaf blade; it serves as the spine fabric within a director system, providing internal switching capacity to the leaf modules. MPN: MSB7570-E. Condition: Refurbished, professionally tested at T.E.S IT-SOLUTIONS for redeployment in existing Mellanox director chassis.

Engineering context. The Switch-IB 2 ASIC delivers 36 EDR 100Gb/s ports per blade, each port composed of 4 lanes at 25Gb/s NRZ. Switch silicon supports adaptive routing, congestion control, and SHARP collective offload (Scalable Hierarchical Aggregation and Reduction Protocol) to accelerate MPI all-reduce operations. Port-to-port latency is sub-100ns. The blade integrates into the chassis backplane and is hot-pluggable for non-disruptive serviceability.

Deployment and use cases. Spine blades populate HPC director switches running MPI workloads (Lustre and GPFS storage fabric, OpenMPI, Intel MPI, NVIDIA NCCL all-reduce), large-scale CFD simulations, EDA grid computing, AI training fabrics, and multi-rack supercomputing clusters where consistent EDR fabric latency is required across thousands of compute nodes.

Technical specifications:

  • Model: MSB7570-E
  • Architecture: Switch-IB 2 ASIC
  • Role: Spine blade for Mellanox modular director chassis
  • Ports per blade: 36 at EDR 100Gb/s
  • Lane rate: 25Gb/s NRZ x4 per port
  • Switch latency: under 100ns port-to-port
  • Switching features: adaptive routing, congestion control, SHARP collective offload
  • Protocol: InfiniBand EDR
  • Form factor: hot-swappable blade module

  • Condition: Refurbished, tested

Compatibility and constraints. Compatible only with Mellanox CS7500-family director chassis configured for EDR 100Gb/s. NOT compatible with HDR (200Gb/s) or NDR (400Gb/s) chassis. NOT a standalone switch — must be installed in a director chassis with matching management modules, fans, and PSUs. Buyer is responsible for verifying chassis revision, fan and PSU compatibility, and MLNX-OS firmware version before deployment.

Frequently Asked Questions (FAQ)

Q. What is the MSB7570-E?
The MSB7570-E is a Switch-IB 2 EDR InfiniBand spine blade with 36 ports at 100Gb/s, for director-class chassis.

Q. Is it a standalone switch?
No. It is a chassis spine blade requiring a compatible director chassis.

Q. Will T.E.S IT-SOLUTIONS confirm the fitment of MSB7570-E before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit before dispatch from EU stock.
