Product Description
The Mellanox MCX4621A-ACAB is a high-performance network interface card (NIC) designed to deliver 25 Gigabit Ethernet (25GbE) connectivity to servers and storage systems. Featuring two ports, this card provides the necessary bandwidth and low latency required for modern data center applications, including virtualization, cloud computing, and high-performance storage solutions. The ConnectX-4 Lx architecture ensures efficient data processing and network acceleration. This NIC supports advanced features such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), which allows for direct memory access between network nodes, bypassing the CPU and operating system kernel. This significantly reduces latency and CPU overhead, leading to improved application performance and greater overall system efficiency. The PCIe Gen 3.0 x8 host interface provides ample bandwidth to the host system, ensuring that the network card is not a bottleneck. The MCX4621A-ACAB is an excellent choice for upgrading existing infrastructure or building new environments that demand higher network speeds than traditional 10GbE. Its combination of speed, low latency, RDMA capabilities, and energy efficiency makes it a versatile solution for a wide range of enterprise and high-performance computing use cases, enabling faster data transfers and more responsive applications.
