Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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 to eight NVIDIA PCIe GPUs and NVIDIA AI Enterprise software, it delivers high performance for a wide range of AI workloads – including Generative AI fine-tuning and inference.
Built on the NVIDIA MGX modular reference design, the Cisco UCS C845A M8 Rack Server is a flexible, scalable, and customizable AI system capable of growing as your AI needs grow. Configure with 2, 4, 6, or 8 PCIe GPUs to address a multitude of workloads ranging from generative AI, graphics and rendering, to virtual desktop infrastructure.
UCS C845A M8 servers can be configured with two to eight NVIDIA GPUs. Depending on the configuration, customers can choose between the PCIe-based NVIDIA H100 NVL, H200 NVL, or L40S GPU. Thanks to the sophistication of the MGX design, other next-generation NVIDIA GPUs are planned to be introduced on this same platform as these GPUs become available.
With a compute node powered by AMD’s new high-end Turin (5th Gen) CPUs, designed specifically for AI workloads, the UCS C845A M8 provides a no-compromise solution for CPU or GPU performance required to avoid bottlenecks within an AI server. Another benefit is the ability to configure the server with the NVIDIA ConnectX-7 NIC and/or NVIDIA BlueField-3 DPUs to handle data traffic in and out of the server.
Systems equipped with NVIDIA H100 NVL or H200 NVL GPU come with a five-year license for NVIDIA AI Enterprise, a cloud-native software platform that streamlines development and deployment of production-grade AI solutions, including AI agents, generative AI, computer vision, speech AI, and more. Easy-to-use microservices optimize model performance with enterprise-grade security, support, and stability, ensuring a smooth transition from prototype to production for enterprises that run their businesses on AI.
Using Cisco Intersight®, customers can see, control, and automate their compute, storage, and networking infrastructure, wherever it is, from one place just as they can do today with their other Cisco UCS® blade or rack servers.
