Frequently Asked Questions
What primary connectivity standards does the HPE 872726-B21 support? +
The HPE 841QSFP28 adapter is a highly versatile dual-port controller that supports both InfiniBand EDR and 100Gb Ethernet connectivity. This dual-protocol capability allows data centers to deploy the card for high-performance computing (HPC) clusters or standard high-speed Ethernet fabric environments, ensuring maximum flexibility for evolving network infrastructure requirements.
How many ports does the HPE 841QSFP28 provide and what is the interface type? +
This network interface card features two QSFP28 ports, which are designed to support high-density 100GbE or EDR InfiniBand connections. These ports provide the physical interface necessary for high-speed fiber connectivity, enabling significant throughput improvements for bandwidth-intensive enterprise applications and reducing latency in server-to-server communication.
Is the HPE 872726-B21 compatible with standard PCIe server slots? +
Yes, this card is engineered to utilize a PCIe 3.0 x16 interface. It is designed to fit into standard PCIe slots on supported HPE ProLiant Gen10 and Gen10 Plus servers. Before installation, ensure your server chassis supports the physical dimensions and the specific PCIe lane configuration required to achieve full 100Gb throughput.
What are the primary use cases for deploying the HPE 841QSFP28? +
The 841QSFP28 is ideal for data-intensive workloads, including large-scale virtualization, high-performance computing, and real-time database analytics. By offloading networking tasks and providing massive bandwidth, it minimizes CPU utilization and optimizes data flow, making it a critical component for organizations managing mission-critical enterprise applications that demand consistent, low-latency performance.
Does this NIC require specific firmware or driver updates for performance? +
To ensure optimal reliability and performance, we recommend checking the HPE Support Center for the latest firmware and driver packages corresponding to your specific operating system. Regularly updating the adapter drivers ensures full compatibility with the latest network protocols and security enhancements, maintaining stable throughput in high-demand environments.
How does this card manage network traffic compared to standard 10GbE adapters? +
Unlike traditional 10GbE adapters, this card supports 100Gb speeds and advanced features like RDMA (Remote Direct Memory Access) over Converged Ethernet. This technology allows for direct data transfer between memory across servers without involving the operating system kernel, which significantly reduces CPU overhead and slashes latency for faster application response times.
Is the 872726-B21 suitable for high-density virtualization environments? +
Absolutely. This adapter is perfectly suited for virtualization clusters that require high-speed interconnects. Its ability to handle 100Gb of traffic across two ports allows for multiple virtual machine traffic streams to be aggregated efficiently, preventing network bottlenecks that typically occur when scaling out virtualized infrastructure in the data center.
What is the physical form factor of the HPE 841QSFP28 card? +
This is a standard PCIe adapter card designed for installation into the riser slots of rack-mounted HPE servers. It features a standard-height, half-length profile, which ensures compatibility with most modern server chassis. The dual-port design allows for port redundancy or load balancing configurations, provided your server setup and network switches are configured accordingly.
