HPE 867707-B21

Overview

The HPE 867707-B21 is a dual-port 10-gigabit Ethernet adapter designed to enhance server network performance by providing two 10GBASE-T RJ-45 ports on a PCIe 3.0 x8 card. It enables high-speed connectivity over existing CAT 6A cabling and automatically supports 1-gigabit speeds for compatibility with older infrastructure. This adapter is ideal for IT environments that require increased bandwidth for tasks such as backup, database replication, and virtual machine migration without the need for costly rewiring.

Key features

Connectivity and compatibility

This adapter fits seamlessly into HPE Gen10 servers, providing a straightforward upgrade path for existing setups. Its use of standard CAT 6A cabling means there is no need to replace copper infrastructure, which helps reduce deployment costs and downtime. The dual RJ-45 ports allow for flexible network configurations, including link aggregation for increased throughput or separate traffic paths for redundancy and security.

• Compatible with a broad range of HPE Gen10 server models
• Supports standard Ethernet protocols for easy integration into existing networks
• Auto-negotiates speeds to maintain connectivity with older network equipment

Performance and reliability

The adapter’s support for jumbo frames and offload technologies like VXLAN and RoCE v2 enhances network efficiency, especially in environments with storage overlays or virtualized workloads. Its firmware-level security features ensure the integrity of the device during every power cycle, reducing risks of tampering. The low power consumption and wide operating temperature range make it a dependable choice for dense server environments where thermal and energy considerations are critical.

Ideal uses and environments

This Ethernet adapter is well suited to IT teams managing HPE Gen10 servers who need to boost network bandwidth for demanding tasks such as backup operations, database replication, and virtual machine migration. It also fits remote offices or branch locations that require faster file transfers but want to maintain their existing copper cabling infrastructure. Its virtualization support and security features make it a strong option for data centers focused on performance and protection.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

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.
