Frequently Asked Questions

What are the primary performance specifications of the Mellanox ConnectX-4 Lx EN MCX4111A-ACAT? +

The MCX4111A-ACAT is a high-performance single-port 10/25GbE network interface card designed for enterprise data centers. It utilizes the PCIe 3.0 x8 host interface, providing low-latency, high-bandwidth connectivity that significantly offloads CPU overhead. This card is engineered to handle intensive virtualization and cloud-native applications, ensuring consistent throughput across demanding network environments.

Which types of transceiver modules are compatible with the MCX4111A-ACAT SFP28 port? +

The SFP28 port on this Mellanox NIC is highly versatile, supporting both 10GbE and 25GbE speeds. It is compatible with a wide range of SFP28 and SFP+ optical transceivers, as well as Direct Attach Copper (DAC) cables and Active Optical Cables (AOCs). We recommend using Mellanox-certified modules to ensure optimal link stability and performance across your fiber infrastructure.

Does the MCX4111A-ACAT support virtualization technologies like SR-IOV? +

Yes, this card fully supports Single Root I/O Virtualization (SR-IOV). By allowing a physical PCIe device to appear as multiple separate physical devices, it enables direct access to the network interface for virtual machines. This reduces latency and eliminates the need for a hypervisor-based software switch, which is essential for maximizing density and performance in virtualized server environments.

How does the MCX4111A-ACAT improve overall server CPU utilization? +

This NIC features advanced hardware offloading engines, including stateless offloads for TCP/UDP/IP traffic. By handling encapsulation, checksum calculation, and packet segmentation directly on the card, it significantly reduces the processing burden on the host CPU. This efficiency allows more server resources to be dedicated to running applications rather than managing network traffic overhead.

Is the MCX4111A-ACAT compatible with common enterprise server operating systems? +

The Mellanox ConnectX-4 Lx family features robust driver support for all major enterprise operating systems, including various Linux distributions, Windows Server, and leading hypervisors like VMware ESXi. Before deployment, ensure your host OS is running a compatible version of the Mellanox OFED (OpenFabrics Enterprise Distribution) stack to leverage the full feature set of the card.

What is the typical deployment scenario for a single-port 25GbE fiber NIC? +

The MCX4111A-ACAT is ideal for high-density enterprise servers, storage clusters, and hyper-converged infrastructure (HCI) nodes. It is commonly deployed in scenarios where 10GbE connectivity is becoming a bottleneck and a scalable transition to 25GbE is required. Its low-profile form factor makes it an excellent choice for compact rack-mount servers where PCIe slot space is limited.

How do I manage and configure the firmware for this Mellanox network card? +

Configuration and firmware updates for the MCX4111A-ACAT are managed through the Mellanox Firmware Tools (MFT) suite. These tools allow you to perform diagnostics, update firmware, and configure internal card settings directly from the host operating system. Keeping the firmware current is essential for maintaining compatibility with updated network switches and ensuring the latest security and performance enhancements are applied.

What is the physical form factor of the MCX4111A-ACAT NIC? +

This card follows a standard low-profile PCIe form factor. It includes both a full-height bracket and a low-profile bracket in the packaging, making it highly adaptable for both standard rack servers and compact 1U/2U server chassis. Its efficient design ensures it fits comfortably into standard x8 PCIe slots without obstructing airflow within the server case.

Can I request a bulk quote for the MCX4111A-ACAT if I am outfitting an entire data center? +
