Product Description
The Lenovo 01KT926, based on Mellanox's ConnectX-5 technology, is a cutting-edge network adapter designed for the most demanding high-performance computing (HPC), artificial intelligence (AI), machine learning (ML), and cloud environments. This dual-port adapter card offers unparalleled speed and efficiency, supporting both InfiniBand EDR (Enhanced Data Rate) and 100 Gigabit Ethernet (100GbE) protocols, providing flexibility for diverse network infrastructures. Each port on the 01KT926 operates at a blazing 100Gb/s, enabling massive data throughput essential for large-scale data analysis, complex simulations, and high-volume storage access. The adapter card leverages advanced offload engines, including Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) and NVMe over Fabrics (NVMe-oF). These offloads significantly reduce CPU utilization and network latency by allowing direct memory access between hosts and storage devices, bypassing the operating system kernel for faster data transfers. Installed via a PCIe Gen3 x16 interface, the adapter ensures ample bandwidth for its high-speed ports. Its robust feature set makes it ideal for applications requiring ultra-low latency and high bandwidth, such as distributed training of deep learning models, high-frequency trading platforms, and high-performance storage solutions. The dual-port design also offers redundancy and increased aggregate bandwidth, making the Lenovo 01KT926 a critical component for modern data centers seeking to maximize performance and efficiency.
