NVIDIA Mellanox MSB7560-E Switch-IB 2 EDR 100Gb/s InfiniBand Leaf Blade: This is an InfiniBand leaf blade module engineered for Switch-IB 2 director-class modular chassis. The MSB7560-E delivers 36 QSFP28 ports operating at EDR 100Gb/s. This is a chassis blade insert, not a standalone 1U switch. This is a refurbished unit.
Engineering Context
Built on the Switch-IB 2 ASIC, the MSB7560-E supports SHARP (Scalable Hierarchical Aggregation and Reduction Protocol) collective offload, accelerating MPI Allreduce and similar collectives directly in the network. Each of the 36 QSFP28 ports operates at EDR 100Gb/s (4 x 25Gb/s NRZ). Port-to-port latency is rated at 90ns by NVIDIA Mellanox. The blade integrates into the chassis backplane to form a non-blocking InfiniBand fabric.
Deployment & Use Cases
Scaling Switch-IB 2 director chassis with additional EDR port density for HPC clusters and AI training systems. MPI-heavy scientific workloads benefiting from SHARP collective offload. Storage fabrics for Lustre, GPFS, or BeeGFS at EDR speed. AI/ML training environments requiring high-bandwidth all-to-all communication.
