WenTian WA7780 G3 AI Server
Lenovo Wentian WA7780 G3 is a server specifically designed for AI large model training. With the advent of the general artificial intelligence era, the parameter quantity of large model training has surpassed the trillion-level threshold, and AI computing power has become a crucial requirement for enterprises to train, develop, and utilize artificial intelligence. Lenovo Wentian WA7780 G3 is here to break through the dilemma of AI computing power supply, providing powerful computing support for general large model training.
Lenovo Wentian WA7780 G3 AI large model training server is based on the fourth and fifth generations of Intel® Xeon® Scalable Processors, equipped with eight NVIDIA HGX™ NVLink® GPUs.
Lenovo Wentian WA7780 G3 AI Large Model Training Server is designed to meet the demands of high-speed data communication between GPU servers in large-scale AI model training scenarios. It supports various external network connection solutions including IB and RoCE. The server can support up to 8 RDMA high-speed network cards, providing an aggregated bandwidth of 3.2 Tb/s. This fully satisfies the communication requirements across nodes during large-scale model training parallel computing. Meanwhile, in terms of local storage design, the server adopts GPU Direct Storage (GDS) technology. Through GDS, GPUs and NVMe achieve fast and low-latency interconnection, which can effectively improve training data loading speed and enhance large model training performance.
