HPE R4N85A A InfiniBand HDR/Ethernet 1-Port QSFP PCIe

Product Description

The HPE R4N85A adapter is a high-performance networking solution designed to cater to the demanding requirements of modern data centers and high-performance computing (HPC) environments. This adapter uniquely supports both InfiniBand HDR and Ethernet protocols, offering exceptional flexibility for organizations that utilize or plan to integrate both networking technologies. The ability to operate in either mode allows for seamless integration into existing infrastructures or the creation of versatile, high-speed network fabrics. Featuring a single QSFP (Quad Small Form-factor Pluggable) port, the R4N85A is capable of delivering extremely high bandwidth, typically supporting speeds such as 200Gb/s for InfiniBand HDR or 100Gb/s for Ethernet, depending on the configuration and transceivers used. The QSFP form factor is standard for high-speed interconnects, enabling efficient data transmission over optical cables. The adapter connects to the server via a PCIe interface, ensuring a high-bandwidth, low-latency connection to the host system. This adapter is particularly valuable for HPC clusters, large-scale data analytics, and cloud computing platforms where rapid data movement and low latency are critical for application performance. Its dual-protocol support simplifies network design and management by potentially reducing the need for separate adapters for different network types. The HPE R4N85A represents a powerful and flexible networking component for environments demanding the highest levels of performance and connectivity.
