Product information

Description

The Mellanox ConnectX-6 Lx EN is a high-performance 25GbE network adapter card engineered for OCP 3.0 form factors. This dual-port SFP28 adapter utilizes a PCIe 4.0 x8 interface to provide reliable, high-speed connectivity for modern enterprise data centers and cloud environments. It incorporates advanced features such as hardware-based cryptography, secure boot, and host management to ensure robust network security and efficient data processing.

Advantages

This network adapter offers exceptional scalability and performance for demanding server workloads. By leveraging the PCIe 4.0 interface, it maximizes throughput while minimizing latency, which is critical for high-speed data center operations. The inclusion of hardware-based security features, including secure boot and encryption, provides an added layer of protection for sensitive data transmissions. Its OCP 3.0 design ensures easy integration into compatible server architectures, promoting efficient airflow and simplified maintenance.

Suitable for

  • High-performance cloud and enterprise data centers
  • Server virtualization and containerized environments
  • Secure network traffic management
  • High-speed storage networking

This adapter may not be suitable for standard desktop computers or workstations that lack OCP 3.0 slots or PCIe 4.0 x8 support. It is specifically designed for server-grade hardware and may not function correctly in consumer-grade motherboards or systems with limited thermal management capabilities.

Key specifications

  • Interface: PCIe 4.0 x8
  • Ports: Dual-port SFP28
  • Data Transfer Rate: Up to 25 GbE
  • Form Factor: OCP 3.0
  • Security: Hardware-based cryptography and secure boot

To install the adapter, ensure the server is powered down and disconnected from the power source. Insert the card into the designated OCP 3.0 slot on the server motherboard, ensuring it is firmly seated. Secure the card using the provided thumbscrew or pull tab mechanism. Once installed, connect the appropriate fiber optic cables to the SFP28 ports. After booting the server, install the latest drivers provided by the manufacturer to ensure optimal performance and compatibility with your operating system.

What to consider before purchase

  • Verify that your server chassis supports the OCP 3.0 form factor
  • Ensure your system has an available PCIe 4.0 x8 slot for maximum performance
  • Confirm compatibility with your existing fiber optic cabling infrastructure
  • Check if your server operating system supports the required network drivers
Ensure that the server environment provides adequate airflow to maintain optimal operating temperatures for the adapter, and always keep the firmware updated to benefit from the latest security patches and performance enhancements.
