NVIDIA Mellanox MSB7520-E Switch-IB EDR InfiniBand Spine Blade Module, 36 Ports, 100Gb/s Per Port: This is a spine blade module for Mellanox modular InfiniBand switch chassis. The MSB7520-E uses the Switch-IB ASIC and provides 36 EDR InfiniBand ports at 100Gb/s each. It is a hot-swappable line card that installs in spine module slots of supported modular chassis. This is a new unit.
Engineering Context
The Switch-IB ASIC was NVIDIA's first dedicated InfiniBand switching silicon for the EDR (100Gb/s) generation. The MSB7520-E spine blade provides 36 EDR ports with 3.6Tb/s aggregate non-blocking bandwidth per module. In a modular chassis spine-leaf architecture, spine blades interconnect all leaf blades, providing full-bisection bandwidth across the fabric. The Switch-IB ASIC supports adaptive routing, congestion control, and hardware-based collective operations for MPI acceleration.
Deployment & Use Cases
Spine module in EDR InfiniBand modular chassis for HPC clusters. Large-scale MPI-based parallel computing requiring full-bisection spine bandwidth. AI/ML training clusters using EDR InfiniBand fabric. Replacement or expansion of spine capacity in existing modular EDR deployments.

Compatibility & Hard Constraints
InfiniBand Only: This is a pure InfiniBand spine blade. It does not support Ethernet. EDR Speed Tier: Operates at EDR (100Gb/s). Not compatible with HDR or NDR at native speeds. HDR/NDR adapters may connect at reduced EDR speed via backward compatibility. Modular Chassis Only: This blade fits specific Mellanox modular InfiniBand switch chassis (CS7500/CS7510 series). It does not fit fixed-configuration switches or Ethernet modular chassis. Spine Slot Only: Install in spine module slots. Do not install in leaf module slots.
