Frequently Asked Questions
What server platforms are compatible with the HPE 874252-B21 network adapter? +
The HPE 874252-B21 is engineered specifically for integration within HPE ProLiant Gen10 and Gen10 Plus server families. It utilizes a standard PCIe form factor, ensuring seamless mechanical and electrical compatibility with the riser slots found in these rack and tower server models. Always verify your specific server chassis's PCIe lane availability and firmware requirements to ensure optimal connectivity and recognized system performance.
Does the 874252-B21 support hardware-based offloading for virtualized environments? +
Yes, this adapter supports advanced offloading features, including TCP/IP offload, UDP checksum, and Receive Side Scaling (RSS). These capabilities are designed to reduce CPU overhead during heavy data processing tasks, making the card an excellent choice for virtualized environments or hyper-converged infrastructures where minimizing host processor burden is critical for maintaining overall system throughput and application responsiveness.
What is the primary interface type for the 874252-B21 Ethernet card? +
The 874252-B21 is a high-performance PCIe-based Ethernet network interface card. It is designed to plug directly into the PCIe expansion slots of compatible HPE servers, providing reliable, high-speed network connectivity. By utilizing the PCIe bus architecture, the card achieves low latency and high data transfer rates, which are essential for demanding enterprise data center workloads and high-traffic network applications.
Can this HPE network adapter be used in non-HPE branded servers? +
While the 874252-B21 is optimized for the HPE ProLiant ecosystem, it utilizes industry-standard PCIe signaling. However, performance and driver stability are only guaranteed when installed in supported HPE server hardware. For non-HPE servers, you may encounter compatibility challenges regarding firmware updates, management interface integration, and physical mounting, so it is highly recommended to stick to the validated HPE hardware list.
What are the power consumption characteristics of the 874252-B21 NIC? +
The HPE 874252-B21 is designed with energy efficiency in mind, adhering to standard power envelope specifications for PCIe networking hardware. It draws power directly from the PCIe slot, eliminating the need for auxiliary power connectors. The card manages heat dissipation effectively under standard operational loads, ensuring it remains within the thermal design parameters of typical HPE server chassis configurations for long-term reliability.
Does the 874252-B21 require specific drivers for Windows Server or Linux environments? +
Yes, proper functionality requires the installation of specific HPE-certified drivers for your respective operating system. You can obtain the latest driver sets through the HPE Support Center. Using the correct version of the firmware and driver is essential to unlock all advanced features, such as VLAN tagging, jumbo frames, and team configurations, ensuring the card operates at peak efficiency within your network infrastructure.
What management features are available for this HPE Ethernet NIC? +
This adapter integrates with HPE’s management ecosystem, allowing administrators to monitor network traffic, status, and health via standard server management tools. It supports various diagnostic utilities that help in identifying link status and connection errors. By streamlining the monitoring process, the card allows IT teams to quickly address potential bottleneck issues, maintaining a consistent and stable high-speed network environment.
Is the 874252-B21 suitable for high-performance computing (HPC) clusters? +
Given its throughput capabilities and low-latency architecture, the 874252-B21 is well-suited for high-performance computing clusters that require consistent data delivery. It provides the reliable interconnectivity needed for demanding parallel processing tasks and inter-node communication. By reducing latency and maximizing bandwidth utilization, it helps meet the rigorous performance demands of modern scientific, financial, and analytical computing workloads within a clustered enterprise network.
