Marketing Information:

NVIDIA MSB7890-ES2F Switch-IB 2 Based EDR InfiniBand 1U Switch 36 QSFP28 Ports 2 Power Supplies AC Unmanaged Standard Depth P2C Airflow Rail Kit RoHS6 | 36-port Non-Blocking Externally-Managed EDR 100Gb/s InfiniBand Smart Switch

NVIDIA Networking provides the world’s first smart switch, enabling in-network computing through the Co-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology. SB7890 has the highest fabric performance available in the market with up to 7.2Tb/s of non-blocking bandwidth with 90ns port-to-port latency.

Faster servers based on PCIe 3.0, combined with high-performance storage and applications that use increasingly complex computations, are causing data bandwidth requirements to spiral upward. As servers are deployed with next generation processors, High-Performance Computing (HPC) environments and Enterprise Data Centers (EDC) will need every last bit of bandwidth delivered with next generation of Extended Data Rate (EDR) InfiniBand high-speed smart switches.
