Lenovo ThinkSystem 57454 10GBASE-T 4-port OCP Ethernet Adapter
- A few left in stock!
The Lenovo 4XC7A08240 is a four-port 10GBASE-T Ethernet adapter that attaches through an OCP 3.0 mezzanine interface, giving compatible ThinkSystem and ThinkAgile servers strong network bandwidth while keeping PCIe slots free for other uses. Each RJ-45 port delivers 10-gigabit throughput over standard copper cabling, so existing Category 6A infrastructure can stay in place while the server gains a significant jump in performance.
At the heart of the adapter sits the Broadcom BCM57454 controller, a chip designed for data center workloads that need consistent, low-latency traffic. Support for RoCE versions 1 and 2 allows RDMA-based applications such as storage replication, distributed databases, and live VM migrations to move data with fewer CPU interrupts, which helps applications keep latency predictable even during peak activity.
For cloud, virtualization, and software-defined deployments, the card brings a complete suite of offloads and management tools. Technologies such as VLAN tagging, TruFlow, RSS, and flow acceleration balance traffic across CPU cores and shape packets before they reach the operating system, letting hypervisors like VMware vSphere, Microsoft Hyper-V, or KVM dedicate more cycles to guest workloads. Jumbo frame support up to 9600 bytes further reduces overhead during large data transfers.
Installation is straightforward. The card slides into the server’s OCP 3.0 slot, draws its power from the system board, and ships with a low-profile bracket that matches standard Lenovo server trays. Operating limits span from 32 to 131 °F with humidity between 5 and 95 percent, so the adapter can handle most controlled data center environments without issue.
Whether you are building a new virtualization cluster, rolling out a hyperconverged platform, or adding extra links for backup and replication, this adapter provides the bandwidth and feature set to keep traffic flowing smoothly.
