Frequently Asked Questions
What primary performance benefit does the HPE 841QSFP28 InfiniBand adapter offer? +
The HPE 841QSFP28 adapter provides high-bandwidth, low-latency connectivity, delivering 100Gb EDR InfiniBand performance. This capability is essential for data-intensive applications such as High-Performance Computing (HPC), complex financial modeling, and large-scale virtualization environments where minimizing CPU overhead and maximizing data throughput are critical requirements for operational efficiency.
Which server infrastructures are compatible with the 872725-B21-VHBRSN adapter? +
This adapter is designed for integration into select HPE ProLiant servers. Because it utilizes the QSFP28 form factor, it is optimized for high-density rack-mount environments requiring high-speed interconnects. We recommend verifying your specific server model’s mezzanine or PCIe slot compatibility to ensure physical and electrical alignment before deployment.
How does InfiniBand EDR technology improve cluster efficiency compared to standard Ethernet? +
InfiniBand EDR significantly reduces latency by offloading protocol processing from the server CPU to the network adapter. By utilizing Remote Direct Memory Access (RDMA), the 841QSFP28 allows data to move directly between the memory of different servers, drastically lowering CPU utilization and accelerating communication times within a cluster compared to traditional Ethernet architectures.
Does the 872725-B21-VHBRSN require specific transceiver modules? +
The QSFP28 port on this adapter supports various 100Gb optics and direct-attach copper cables. To maintain signal integrity and performance standards, ensure that your chosen cabling or transceiver is compatible with EDR InfiniBand specifications. Proper selection of passive or active copper cables and fiber optics is necessary to match the physical reach of your data center fabric.
Can this InfiniBand card be used for storage area network traffic? +
Yes, this card is frequently deployed in environments requiring high-performance storage connectivity. By providing high-throughput and ultra-low latency, it supports technologies like NVMe-over-Fabrics, allowing storage arrays to interface with compute nodes at speeds that prevent bottlenecks common in standard storage network configurations.
How should this adapter be managed within an existing HPE network environment? +
Management is typically handled through standard HPE infrastructure management tools and drivers compatible with your operating system. Once installed, the card integrates with the fabric management software required for InfiniBand subnet administration, allowing administrators to monitor port status, link speed, and overall health within the fabric topology.
Is the 841QSFP28 suitable for GPU-accelerated computing nodes? +
This adapter is an excellent choice for GPU-heavy clusters. High-performance computing tasks, such as deep learning and artificial intelligence training, rely on the low latency of InfiniBand to synchronize massive datasets across multiple GPU nodes. The 100Gb bandwidth ensures that the network does not limit the processing power of your accelerated nodes.
What is the physical port configuration of this HPE InfiniBand NIC? +
The 872725-B21-VHBRSN features a single QSFP28 port. This high-density port design allows for a streamlined cabling layout while providing the full 100Gbps bandwidth required for modern EDR InfiniBand fabrics. It is engineered for reliability in high-uptime enterprise environments where consistent, high-speed data transmission is a daily operational necessity.
