HPE InfiniBand NDR adapters are based on the NVIDIA ConnectX®-7 smart host channel technology.
The adapters support the InfiniBand and Ethernet functions for HPE servers. HPE InfiniBand NDR adapters are designed for customers that require ultra-low latency and high-bandwidth InfiniBand interconnector in their high-performance computing (HPC) systems.
Overview
The HPE NDR InfiniBand adapters include single-port and dual-port options. The single-port adapters are offered in InfiniBand NDR speeds (400Gb/s) and Ethernet (400GbE) with OSFP or QSFP112 connectors or NDR200 (200Gb/s) speeds and Ethernet (200GbE) with OSFP connectors. The dual-port adapters are offered in InfiniBand NDR200 (200Gb/s) and Ethernet (200GbE) enabled with QSFP112 connectors.
