HPE 817738-B21

Overview

The HPE 817738-B21 is a dual-port 10 Gigabit Ethernet network adapter designed to upgrade server connectivity without replacing existing copper cabling. It fits into a PCIe 3.0 x4 slot and uses standard RJ-45 connectors, enabling a smooth transition from 1 Gb to 10 Gb speeds. Powered by the Intel X550-AT2 controller, it efficiently manages network traffic while reducing CPU load, making it well suited for demanding server environments handling virtualization, databases, or web services.

Key features

• Two 10 Gb Ethernet ports with RJ-45 connectors allow easy integration into existing copper-based networks.
• PCIe 3.0 x4 interface delivers high bandwidth for fast data transfers and low latency.
• Intel X550-AT2 controller offloads packet processing to reduce CPU overhead and improve overall server performance.
• Support for jumbo frames enhances throughput by allowing larger packets to be transmitted efficiently.
• SR-IOV and small-packet acceleration optimize network performance in virtualized and high-density traffic environments.
• Includes a low-profile bracket for installation flexibility in compact 1U or 2U server chassis.
• Energy-efficient design with a power draw of only 11.15 watts helps reduce operational costs.
• Wide operating temperature range from 41 to 140 degrees Fahrenheit ensures reliable performance in various data center conditions.
• Compliance with RoHS 6/6 and WEEE standards supports environmental sustainability goals.
• Full IPv4 and IPv6 support keeps the adapter compatible with current and future network protocols.

Connectivity and compatibility

This adapter is designed to fit seamlessly into servers with available PCIe 3.0 x4 slots, making it a practical upgrade for existing infrastructure. The use of RJ-45 connectors means it works with standard copper Ethernet cables, avoiding the need for costly fiber optic rewiring. Its compatibility with both IPv4 and IPv6 networks ensures it remains relevant as network protocols evolve.

Performance and reliability

By offloading packet processing tasks to the Intel X550-AT2 controller, the adapter reduces CPU load, which is critical for servers running multiple virtual machines or handling heavy network traffic. Features like jumbo frame support and SR-IOV improve throughput and efficiency, especially in environments with high data density. The card’s reliable operation across a broad temperature range and low power consumption make it suitable for demanding data center conditions.

Ideal uses and environments

This network adapter is a strong choice for IT administrators looking to boost network speeds in data centers, enterprise servers, or high-performance computing clusters without replacing existing cabling. It fits well in setups that require efficient handling of virtualization, database transactions, or web hosting. Its low-profile design also makes it suitable for space-constrained server racks.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
