HP Infiniband QDR/Ethernet 10Gb 2-port 544M Adapter 644160-B21

Description

HP InfiniBand QDR / Ethernet 10Gb 2-Port 544M Adapter – 644160-B21

The HP InfiniBand QDR / Ethernet 10Gb 2-Port 544M Adapter (644160-B21) is a versatile high-performance network interface card that supports both InfiniBand QDR and 10Gb Ethernet connectivity in a single adapter. Designed and validated by Hewlett‑Packard Enterprise, this adapter provides flexible, low-latency networking for demanding compute and storage environments.

Dual-Mode Networking for Performance and Flexibility

This adapter supports QDR InfiniBand (Quad Data Rate) and 10Gb Ethernet in a dual-port configuration, giving organizations the ability to unify high-throughput cluster networking with standard Ethernet infrastructure. This makes it ideal for environments that require both high-performance interconnects and general-purpose network access.

High-Throughput InfiniBand QDR and 10Gb Ethernet

• InfiniBand QDR: Delivers up to 40 Gb/s interconnect performance for HPC clusters, parallel computing, and storage traffic.

• 10Gb Ethernet: Provides familiar and flexible Ethernet connectivity for general network traffic, IP-based services, and data center communication.

Low Latency for Demanding Workloads

The QDR InfiniBand mode offers extremely low latency, making this adapter well suited for high-performance computing (HPC), virtualization clusters, and data analytics platforms where fast data movement is critical. The 10Gb Ethernet ports support lower-latency IP networking for connected services.

Broad Compatibility and Easy Integration

This adapter uses a standard PCIe interface and is compatible with a wide range of HPE servers and supported operating systems. It integrates easily into server environments where both InfiniBand and standard Ethernet connectivity are needed without additional interface cards.

Enterprise-Grade Reliability

As a genuine HPE component, the 644160-B21 adapter is tested for continuous operation under demanding workloads. It delivers stable performance and predictable behavior, making it suitable for enterprise and research environments.

Frequently Asked Questions (FAQ)

What is InfiniBand QDR?
QDR (Quad Data Rate) InfiniBand is a high-performance interconnect technology that provides up to 40 Gb/s bandwidth and very low latency, often used in HPC and storage clustering environments.

Can this adapter be used for both InfiniBand and Ethernet at the same time?
Yes. The dual-port design allows each port to operate in either InfiniBand QDR or 10Gb Ethernet mode depending on how the network is configured and the drivers used.

Is additional hardware required to use InfiniBand mode?
Yes. To use InfiniBand mode, compatible InfiniBand switches and appropriate cabling are required. For Ethernet mode, standard network infrastructure (switches, copper or fiber) can be used.

Does the adapter support standard Ethernet protocols?
Yes. In 10Gb Ethernet mode, the adapter supports normal IP networking protocols and is compatible with existing Ethernet infrastructure.

What servers is this adapter compatible with?
It is compatible with HPE servers that support PCIe expansion cards and have driver support for InfiniBand and Ethernet—verify specific server models before deployment.
