Description
Gen4 ExpressBox4400 – High-performance GPU accelerator with NVIDIA® GPU support
The Gen4 ExpressBox4400 is a high-performance PCIe Gen4 expansion solution designed specifically for AI workflows, high-performance computing (HPC) and data analytics. With support for up to four NVIDIA® A100 PCIe GPUs, the system delivers 2.5x FP64 performance compared to the NVIDIA® V100. The eight PCIe Gen 4 slots allow for flexible configuration, whether for HPC acceleration, FPGA data processing or memory expansion.
Highest data throughput for AI, deep learning and data science
Thanks to the PCIe Gen4 architecture, the Gen4 ExpressBox4400 offers a data throughput of up to 128 Gbit/s, which is twice as fast as PCIe Gen 3. Two dedicated PCIe Gen4 x16 HBA/NIC slots ensure optimal connectivity to server and network infrastructures, while the configurable eight PCIe Gen4 x8 slots provide space for FPGAs, memory add-in cards or specialized accelerators.
Robust and modular design for industrial and mobile AI applications
The Gen4 ExpressBox4400 is designed for use in transportable and industrial AI environments. The robust housing and optional AC or DC power supply make it ideal for ground, air and sea-based applications. Additional features such as dynamic fan speed control, IPMI-based system monitoring and replaceable fan filters ensure maximum efficiency and longevity.
With support for the latest PCIe Gen4 add-in cards, the Gen4 ExpressBox4400 offers a future-proof solution for AI training, deep learning, simulations and big data analysis. Flexible slot and host uplink configuration allows throughput to be optimized and system performance to be tailored to specific workloads.
