Cisco UCS C845A M8 Rack Server

Data Sheet

Product Overview

The Cisco UCS® C845A M8 Rack Server is a highly scalable, flexible, and customizable AI system based on the NVIDIA MGX reference design for accelerated computing. With support for two (2) to eight (8) NVIDIA or AMD PCIe GPUs and NVIDIA AI Enterprise software, it delivers high performance for a wide range of AI workloads – including Generative AI fine-tuning, RAG, and inference.

The Cisco UCS C845A M8 Rack Server is designed to address the most demanding AI workloads. As an integral component of Cisco® AI PODs (Cisco Validated Designs for AI), the Cisco UCS C845A M8 provides a robust foundation for modern AI infrastructure, allowing organizations to easily scale their AI capabilities with confidence.

With support for 2, 4, 6, or 8 NVIDIA GPUs – including the NVIDIA RTX Pro 6000 Blackwell, H100 NVL, H200 NVL, L40S, and also supports AMD Instinct MI210 GPUs – this system offers unparalleled flexibility to meet the diverse needs of enterprises. Leveraging the sophistication of the MGX modular reference design, this platform is also future-ready, with next-generation NVIDIA GPUs expected to seamlessly integrate as they become available.

As part of Cisco AI PODs, the UCS C845A M8 is designed to accelerate workloads such as large-scale deep learning, Large Language Model (LLM) training, model optimization, and AI inference. It supports hybrid AI workflows across cloud and edge environments, making it the perfect solution for enterprises working on cutting-edge applications such as AI agents, conversational AI, intelligent search, and virtual desktops. Enhanced by 5th Gen AMD EPYC "Turin" CPUs and NVIDIA BlueField-3 DPUs, this server eliminates performance bottlenecks, ensuring optimal CPU and GPU utilization for data-intensive workloads.

With seamless integration into Cisco Intersight®, customers can manage their entire infrastructure – including compute, storage, and networking – through a unified interface. The Cisco UCS C845A M8, now part of Cisco AI PODs, is the ideal platform for organizations seeking to scale their AI initiatives with confidence and efficiency.
