Lenovo 4XC7A08240

Overview

The Lenovo 4XC7A08240 is a four-port 10GBASE-T Ethernet adapter designed to enhance network performance in compatible ThinkSystem and ThinkAgile servers. It connects via an OCP 3.0 mezzanine interface, delivering 10-gigabit speeds over standard Category 6A copper cabling. Powered by the Broadcom BCM57454 controller, this adapter supports advanced data center workloads with low latency and efficient traffic management.

Key features

• Four 10GBASE-T RJ-45 ports provide high-speed connectivity using existing copper infrastructure.
• RoCE versions 1 and 2 support enables RDMA for reduced CPU overhead and predictable latency in storage replication and live VM migrations.
• Traffic management technologies like TruFlow, RSS, and flow acceleration optimize packet handling and balance loads across CPU cores.
• Jumbo frame support up to 9600 bytes reduces overhead during large data transfers, improving efficiency.
• Compatible with virtualization platforms such as VMware vSphere, Microsoft Hyper-V, and KVM, supporting software-defined networking and network function virtualization.
• Low-profile bracket included for easy installation in Lenovo server trays, drawing power directly from the system board.
• Designed to operate reliably within typical data center environmental conditions, including temperatures from 32 to 131 °F and humidity from 5 to 95%.

Connectivity and compatibility

This adapter fits seamlessly into Lenovo ThinkSystem and ThinkAgile servers equipped with OCP 3.0 slots, freeing up PCIe slots for other expansion cards. Its four RJ-45 ports use standard copper cabling, allowing you to maintain your existing Category 6A infrastructure without costly upgrades. The card supports a range of virtualization and cloud environments, making it a versatile choice for modern data centers.

Performance and reliability

Built around the Broadcom BCM57454 controller, the adapter delivers consistent low-latency performance essential for demanding data center applications. Offload features reduce CPU load by handling network traffic efficiently, which is critical for environments running storage replication, distributed databases, or live virtual machine migrations. The robust operating range ensures stable operation in typical data center conditions.

Ideal uses and environments

This Ethernet adapter is well suited to data centers deploying virtualization clusters, hyperconverged infrastructure, or software-defined networking solutions. It supports high-throughput, low-latency workloads and is a strong choice for IT professionals looking to maximize network bandwidth while maintaining existing cabling. Its compatibility with Lenovo servers and virtualization platforms makes it a practical upgrade for expanding network capacity and improving traffic management.

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.
