Product Description
The Mellanox MCX4121A-XCAT-LOW is a high-performance, energy-efficient 10 Gigabit Ethernet Network Interface Card (NIC) from the ConnectX-4 Lx family. Designed to meet the demands of modern data centers, cloud environments, and high-performance computing (HPC) clusters, this adapter provides robust connectivity and advanced features. Its dual-port configuration ensures redundancy and increased bandwidth, while the low-profile form factor makes it suitable for a wide range of server chassis, including those with limited space. Leveraging the advanced capabilities of the ConnectX-4 Lx controller, this NIC offers significant offload engines to reduce CPU overhead. These include stateless TCP/UDP/IP checksum offloads, which free up the host processor for application tasks. Furthermore, it supports Remote Direct Memory Access over Converged Ethernet (RoCE), enabling low-latency, high-bandwidth memory access between nodes in a cluster, crucial for HPC and storage applications. The inclusion of Single Root I/O Virtualization (SR-IOV) enhances virtualization performance by allowing direct assignment of network resources to virtual machines. With its PCIe 3.0 x8 interface, the MCX4121A-XCAT-LOW ensures high throughput and low latency for data-intensive workloads. The adapter is engineered for reliability and performance, making it an ideal choice for demanding network environments that require high speed, efficiency, and advanced networking features. Its compatibility with various operating systems and network protocols further solidifies its position as a versatile networking solution.
