Frequently Asked Questions
What are the primary performance specifications of the Mellanox MCX4121A-ACFT? +
The MCX4121A-ACFT is a ConnectX-4 Lx EN adapter featuring dual 25GbE SFP28 ports. It utilizes a PCIe 3.0 x8 interface, providing high-bandwidth connectivity and low-latency performance essential for data centers, cloud infrastructure, and enterprise applications requiring efficient throughput for demanding virtualization and storage workloads.
Does the MCX4121A-ACFT support legacy 10GbE network environments? +
Yes, the ConnectX-4 Lx architecture is designed with backward compatibility in mind. The SFP28 ports on this card are capable of supporting 10GbE SFP+ optical modules or direct-attach copper cables, allowing you to seamlessly integrate this 25GbE adapter into existing 10GbE infrastructure before future-proofing to higher speeds.
Which operating systems are compatible with the Mellanox MCX4121A-ACFT? +
This network interface card offers broad compatibility with most major enterprise-grade operating systems, including various distributions of Linux, Windows Server versions, and common hypervisors like VMware ESXi. For optimal performance and feature set utilization, we recommend ensuring you are running the latest Mellanox OFED or WinOF-2 drivers provided by NVIDIA/Mellanox.
How does the MCX4121A-ACFT improve CPU efficiency in virtualized environments? +
This adapter utilizes advanced hardware offloading technologies, including SR-IOV, VXLAN, and NVGRE hardware offloads. By handling network traffic processing directly on the card rather than consuming host CPU cycles, the MCX4121A-ACFT significantly reduces overhead, allowing your servers to dedicate more processing power to virtual machine workloads and overall application performance.
What is the physical form factor of the MCX4121A-ACFT card? +
The MCX4121A-ACFT comes in a standard low-profile PCIe form factor. This compact design makes it an ideal choice for 1U and 2U rack-mount servers where physical space is at a premium. It typically ships with the necessary brackets to fit both low-profile and full-height PCIe expansion slots within your chassis.
Can the MCX4121A-ACFT be used in high-availability clustering setups? +
Absolutely. With its dual-port configuration, this card supports link aggregation and failover redundancy. When properly configured through your switch infrastructure and host OS teaming or bonding drivers, the MCX4121A-ACFT ensures continuous network connectivity, protecting your critical enterprise applications against individual cable or port failures during routine operation.
What type of optics or cabling should I use with this NIC? +
The SFP28 interface supports a variety of media depending on your distance requirements. You can utilize 25GBASE-SR or 25GBASE-LR optical transceivers for fiber-based links, or passive and active copper DAC cables for short-reach connections within the same rack. Always ensure the transceivers are compatible with the specific Mellanox firmware version installed on your card.
Is the MCX4121A-ACFT suitable for RoCE deployment? +
The ConnectX-4 Lx family supports RoCE (RDMA over Converged Ethernet) v1 and v2. This capability allows for direct memory access between servers over Ethernet, which drastically decreases latency and improves storage performance. It is a highly recommended deployment for high-performance computing clusters and NVMe-over-Fabrics storage arrays where low latency is mission-critical.
