NVIDIA Mellanox MSB7510-E Switch-IB EDR 100Gb/s InfiniBand Leaf Blade — 36 QSFP28 Ports: This is a 36-port EDR InfiniBand leaf blade module designed for the Mellanox CS7500/CS7510 director-class chassis switch family. It is a chassis-resident leaf line card, not a standalone 1U switch. This is a new unit.
Engineering Context
The MSB7510-E is built on the Switch-IB silicon and supports EDR (100Gb/s) InfiniBand per QSFP28 port. It plugs into a CS7500-series director chassis to provide 36 fabric-side QSFP28 ports per blade. Switch-IB delivers low end-to-end latency in the sub-microsecond range typical of EDR director platforms and supports Mellanox SHARP collective acceleration in compatible firmware revisions. The blade is RoHS6 compliant and designed for the controlled airflow of the parent chassis.
Deployment & Use Cases
Capacity expansion in CS7500 / CS7510 EDR director chassis used in HPC and AI training fabrics. Spine-leaf consolidation in large multi-rack InfiniBand clusters. MPI-heavy supercomputing workloads requiring full-bisection EDR bandwidth. Storage fabrics for Lustre, GPFS/Spectrum Scale, and parallel NVMe-oF over InfiniBand.

Compatibility & Constraints
Compatible only with NVIDIA Mellanox CS7500-series director-class chassis that accept the MSB7510 leaf blade family. Pairs with EDR-capable adapters such as ConnectX-4, ConnectX-5, and ConnectX-6 IB. Not a standalone switch — cannot operate outside its parent chassis. Not interchangeable with HDR (200Gb/s) or NDR (400Gb/s) blade slots; chassis must be EDR-class. Requires QSFP28 EDR-rated transceivers or Mellanox copper/AOC cables.
