Connectivity and compatibility

This network adapter is designed to fit into a PCIe 2.0 x4 slot, making it compatible with servers that support this interface, specifically Lenovo ThinkServer RD550 and RD650 models. The four Ethernet ports provide multiple physical connections, which is beneficial for separating different types of network traffic or increasing overall bandwidth. Its virtualization and QoS features make it well suited for complex network environments where traffic management is critical.

Performance and reliability

With the Intel i350 chipset at its core, this adapter delivers consistent and stable network performance. The inclusion of I/O virtualization and port partitioning allows for efficient bandwidth distribution, which is essential in multi-tenant or multi-application server environments. Energy efficient Ethernet and DMA coalescing contribute to lower power consumption and reduced heat generation, supporting reliable operation in dense server racks.

Ideal uses and environments

This adapter works well in virtualization hosts and data centers that require multiple network connections within a single server chassis. It is a strong choice for IT professionals looking to expand Ethernet connectivity without adding multiple cards, especially in Lenovo ThinkServer RD550 and RD650 systems. Its features support workloads that depend on consistent wired performance, such as storage networks, backup systems, and management traffic separation.

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.
