4U GPU Server with Dual-Socket 4th Gen Intel Xeon Processors | AI Training & Inference Rack Server with GPU

ChangFan CF-4621-8G – Intel High-Performance GPU Server

The CF-4621-8G is a standard 4U rack-mount high-performance GPU server powered by 1st/2nd/3rd/4th Gen Intel Xeon Scalable processors, with 24 DDR4 RDIMM slots supporting up to 2TB of memory and up to 8/10 GPU cards per system. It supports GPUs such as the NVIDIA RTX 4090, A100, A800, H100 and H800, and is ideal for AI, deep learning training and inference, mathematical modeling and HPC — the perfect hardware platform for compute-intensive workloads.

Key Features:
● Independent R&D, extreme computing power: Designed in-house by ChangFan Technology, the AI system supports up to 8 AI chips or GPU cards, is compatible with NVIDIA A100 graphics cards, and offers multiple power-delivery options without hardware modification — an unmatched architecture for customers pursuing maximum compute performance.
● Standard 4U rack-mount design: Measuring 798mm × 436mm × 176mm, the standard 4U chassis provides generous internal space and cooling capacity for standardized data centers and server rooms.
● 1st–4th Gen Intel Xeon Scalable processors: Supports 1st/2nd/3rd/4th Gen Intel Xeon Scalable CPUs (including Ice Lake), two high-TDP processors, with 2 onboard M.2 slots — delivering supercomputing-class capability.
● Ultra-high-capacity memory: 24× DDR4 RDIMM slots supporting up to 2TB, fully satisfying memory-intensive workloads such as AI training and big-data analytics.
● Highly scalable storage: 8× 2.5-inch SATA/SAS hot-swap bays plus 2× M.2 slots flexibly cover both system and data storage needs.
● Ultimate GPU expansion: Up to 8/10 GPU cards per system, supporting mainstream GPUs such as NVIDIA RTX 4090, A100, A800, H100 and H800 for compute-intensive AI training, inference and graphics rendering.
● Extensive PCIe expansion: 8× PCI-E x16 slots (Gen3/Gen4 x16 link, full-height full-length) support a wide range of add-on cards.
● Efficient cooling and intelligent management: 5 dedicated temperature-controlled fans for GPU servers keep the GPU cluster thermally stable in the dense 4U chassis; the IPMI remote management port enables remote monitoring and O&M, reducing on-site maintenance costs.
● Reliable redundant power: A 2200W Platinum 1+1 redundant power supply (3+1 or 4+1 configurations available) keeps mission-critical workloads running 24/7 without interruption.
● Broad OS compatibility: Full support for mainstream x86 operating systems including Linux and Windows, adapting flexibly to all major AI frameworks and software environments.

Applications:
● AI & deep learning: large-model training and inference, neural network deployment
● High-performance computing (HPC): scientific computing, mathematical modeling and complex numerical analysis
● Graphics rendering & post-production: 3D rendering, film VFX, virtual production
● Cloud computing & VDI virtualization: GPU virtualization, cloud gaming, remote graphics workstations
