Frequently Asked Questions

What are the primary performance advantages of the HPE 620QSFP28 adapter for high-density environments? +

The HPE Ethernet 4x25Gb 620QSFP28 adapter offers extreme bandwidth by consolidating multiple high-speed lanes into a single QSFP28 port. By supporting 100GbE throughput via four-channel 25GbE connectivity, it significantly reduces latency and optimizes data throughput for demanding virtualization, cloud computing, and high-performance computing (HPC) clusters, ensuring your server fabric keeps pace with modern application requirements.

Which specific HPE ProLiant server generations are compatible with the 817762-B21 network card? +

This adapter is engineered for seamless integration with HPE ProLiant Gen10 and select Gen9 rack and tower servers. It utilizes a standard PCIe slot architecture to provide high-speed connectivity. For specific compatibility with your existing infrastructure, verify that your server chassis has an available PCIe 3.0 or higher x16 expansion slot to accommodate the card’s form factor and throughput capacity.

Does the HPE 620QSFP28 support advanced network offloading technologies? +

Yes, this NIC includes integrated hardware offloads designed to improve CPU efficiency. It supports essential features like RDMA over Converged Ethernet (RoCE), which minimizes latency for storage and messaging traffic. By offloading protocol processing from the server CPU, the adapter ensures that host resources remain available for primary application workloads rather than network overhead.

How does the QSFP28 port design on this adapter affect cabling options? +

The QSFP28 interface provides versatile deployment options, allowing you to use direct-attach copper (DAC) cables for short-range rack connectivity or optical transceivers for longer distances. This modularity makes it an excellent choice for data centers that require high-speed uplinks to top-of-rack switches while maintaining the flexibility to scale cabling infrastructure as your network needs evolve over time.

Is the HPE 817762-B21 suitable for virtualized server environments? +

Absolutely. This adapter is built to handle the heavy traffic demands of virtualized environments by supporting advanced features like SR-IOV (Single Root I/O Virtualization). This allows a single physical port to appear as multiple virtual functions, giving virtual machines direct access to the hardware for near-native performance and improved isolation between tenant traffic streams.

What is the typical management interface for configuring this network card? +

Management is performed through standard HPE server tools, including the Intelligent Provisioning system and Integrated Lights-Out (iLO). Once installed, the NIC is detected by the OS as a standard network controller, allowing you to manage driver settings, link speeds, and advanced features like VLAN tagging or teaming through your preferred operating system networking stack or the HPE management utilities.

How does the power efficiency of the 620QSFP28 impact data center operations? +

This card is designed with power-efficient ASIC architecture, helping to keep the overall power footprint of your server rack lower compared to older, multi-card configurations. By achieving 100GbE performance through a single PCIe adapter, you effectively reduce the number of required slots and cables, lowering your total energy consumption and heat dissipation requirements within high-density server cabinets.

Can this adapter be used in non-HPE branded servers? +

While the 817762-B21 is optimized specifically for HPE ProLiant platforms and validated through HPE firmware testing, it utilizes standard PCIe signaling. However, for maximum stability and consistent performance within enterprise environments, it is recommended to use this card within supported HPE ecosystems, as driver and firmware integration is primarily tuned for ProLiant server management stacks and testing environments.

How can I obtain a bulk quote for multiple HPE 817762-B21 units? +
