NVIDIA Mellanox MSB7700-ES2F Switch-IB EDR 36-Port 1U Managed InfiniBand Switch: This is a 1U rack-mount InfiniBand switch with 36 non-blocking QSFP28 ports running at EDR (100Gb/s) per port. The MSB7700-ES2F uses an externally managed Subnet Manager for fabrics up to 2,048 nodes. This is not an unmanaged switch and not an Ethernet switch. This is a new unit.
Engineering Context
The MSB7700-ES2F provides 7.2 Tb/s of bidirectional aggregate throughput across 36 EDR ports, with port-to-port latency of approximately 90 nanoseconds. The switch is built around the Switch-IB ASIC and is the externally managed (ES2F) variant of the SB7700 family. Dual hot-swappable AC power supplies and N+1 redundant fans support continuous operation. The chassis is short-depth for compact data center racks. Typical power draw is approximately 136W.
Deployment & Use Cases
Spine and leaf switches in HPC InfiniBand fabrics. Storage cluster backbones for Lustre, GPFS, and BeeGFS deployments. Top-of-rack EDR switching for AI training clusters using NCCL collectives. GPU server interconnects for HPL, HPCG, and CFD workloads.
Technical Specifications

Compatibility & Constraints
The MSB7700-ES2F operates in InfiniBand mode and is compatible with EDR, FDR, and QDR adapters and cables negotiated to their respective speeds. It pairs with ConnectX-4, ConnectX-5, and ConnectX-6 VPI HCAs in InfiniBand mode. Subnet Manager runs externally (NVIDIA UFM or OpenSM on a host); this is not the MSB7700-EB2F managed-onboard variant. Not for Ethernet-only deployments. Requires QSFP28 cables or transceivers for native EDR connectivity.
