Product Description
The Mellanox CX455A is a cutting-edge network adapter engineered to deliver unparalleled performance for the most demanding data-intensive applications. It supports 100 Gigabit Ethernet (GbE) over InfiniBand Enhanced Data Rate (EDR), providing extremely high bandwidth and low latency essential for high-performance computing (HPC), artificial intelligence (AI), and machine learning (ML) workloads. This adapter features a single QSFP28 port, capable of accommodating high-speed optical transceivers for network connectivity. The PCIe x16 interface ensures maximum bandwidth to and from the host system, minimizing communication overhead. Its low-profile design allows for installation in a wider range of server chassis, including dense computing environments. The CX455A is built upon Mellanox's advanced networking technology, offering features such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE) and InfiniBand, which significantly accelerate application performance by bypassing the CPU and operating system kernel for data transfers. This makes it an indispensable component for modern data centers requiring extreme network speeds and efficiency.
