Frequently Asked Questions
What primary networking protocol does the HPE 872725-B21 support? +
The HPE 872725-B21 is specifically designed for InfiniBand EDR environments. It operates at 100Gb/s speeds, providing the extremely low latency and high bandwidth throughput required for high-performance computing clusters and data-intensive applications where standard Ethernet protocols may introduce unwanted bottlenecks.
What type of physical transceiver or cable connection does this card utilize? +
This adapter features a single QSFP28 port. This standardized interface allows you to connect via QSFP28 direct-attach copper cables for short-range top-of-rack deployments or compatible optical transceivers for longer distance requirements, ensuring flexibility in your physical layer infrastructure design.
Can this InfiniBand adapter be installed in standard HPE ProLiant servers? +
Yes, this card is designed for seamless integration into compatible HPE ProLiant Gen10 and Gen10 Plus servers. It utilizes a standard PCIe slot form factor, making it an ideal upgrade for compute nodes that require high-speed interconnects for distributed workloads and parallel processing tasks.
What are the main performance advantages of using EDR InfiniBand over 10GbE? +
Moving to InfiniBand EDR 100Gb provides a massive increase in bandwidth and a significant reduction in CPU overhead. By offloading protocol processing from the server CPU to the adapter, this card enables faster data movement and lower latency, which is critical for MPI-based applications and large-scale storage arrays.
Does this adapter support advanced traffic offloading features? +
The HPE 841QSFP28 supports advanced offloading capabilities, including RDMA (Remote Direct Memory Access). RDMA allows the adapter to transfer data directly between the memory of two servers without involving the operating system or CPU, resulting in ultra-low latency and higher overall application efficiency.
Is this card suitable for high-density cluster environments? +
Absolutely. Because this card provides 100Gb/s connectivity, it is the standard choice for high-density computing clusters where inter-node communication speed is the primary limiting factor for performance. It facilitates efficient scaling of HPC resources while maintaining the reliable connectivity needed for massive data transfers.
How is this card managed and configured within the server environment? +
The card is managed through standard HPE server utilities and compatible InfiniBand fabric management software. Drivers are readily available for major enterprise operating systems, allowing administrators to configure the adapter parameters and monitor link health through the existing server management toolset without requiring proprietary management hardware.
What is the expected power consumption profile for the 872725-B21? +
As a high-performance 100Gb/s adapter, it is designed to operate within the thermal and power limits defined by the PCIe bus specifications for server components. It offers an optimized power-to-performance ratio, ensuring that it provides the necessary high-speed connectivity without placing excessive strain on your server’s internal cooling or power distribution systems.
