Overview

This chapter contains the following topics:

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 to eight AMD or NVIDIA PCIe GPUs and NVIDIA AI Enterprise software (for NVIDIA GPUs), it delivers high performance for a wide range of AI workloads.

Depending on the configuration, the server can support PCIe-based NVIDIA H200 NVL, NVIDIA L40S, NVIDIA RTX Pro 6000 and RTX Pro 6000D, NVIDIA RTX Pro 4500, and AMD MI210 GPUs with potential support for additional GPUs as they become available. With a compute node powered by AMD’s new high-end Turin (5th Gen) CPUs, the UCS C845A M8 provides robust functionality for a multitude of workloads ranging from generative AI, graphics and rendering, to virtual desktop infrastructure.

For more information and GPU and CPU compute options, see Summary of Features.

For north-south traffic, the server supports NVIDIA Bluefield-3 DPUs, NVIDIA ConnectX-7 NICs, or Intel X710 OCP cards. With a configuration consisting of NVIDIA ConnectX-7 NIC and/or NVIDIA BlueField-3 DPUs, the AI system can handle high volumes of data traffic in and out of the server.

  • NVIDIA® H200 Server PCI Express Module (NVL) GPUs. NVIDIA NVLink (NVL) is a high-speed, GPU-to-GPU interconnect technology supported through directly connecting multiple GPUs to function as a single, unified accelerator.

  • AMD MI210 PCIe GPUs.

For east-west traffic, up to four NVIDIA ConnectX-7s or Bluefield-3 B3140H SuperNICs are supported for GPUs enabling AI model training across a cluster of dense-GPU servers.

For more information about N-S and E-W networking support, see Summary of Features.

The server is offered in fixed configurations with resources optimized for intensive AI and HPC workloads.

For additional supported hardware features, see Summary of Features.

External Features

The server contains modular groups of components that are arranged into the following trays.

  • Fan and Storage Locations

  • Redundant PSU Locations

Fan and Storage Locations

The server contains 5 fans for proper cooling as well as four groups of ES.1 NVMe SSDs for storage.

Redundant PSU Locations

The system includes four 3200W power supply units (PSU) configured for 12V CRPS N+1 redundancy.


Note
For 12V CRPS N+1

If one PSU fails, troubleshoot the cause and replace the failing PSU immediately. If a PSU fails the system keeps running at full performance.

Component Locations

The server is designed as a modular system with subsystems for compute, cooling, and so on. Subsystems are generally arranged in trays, which are field replaceable units (FRUs). However, some components in a subsystem or tray are not individually field-replaceable. The following main components are not field replaceable.

  • MGX HPM Board

  • PCIe SW Board

  • DC-SCM Module

  • PDB Board

  • HSC Board

  • Fan Board

  • E2.S Backplanes

  • FIO Board

For the complete list of FRUs and the procedures to replace them, see Server Components below.

Server Components

The server has the following main components. Some sub components are contained within specific trays in the server. For example, the CPUs, heatsinks, and DIMMs are contained on the CPU tray. If these components need to be replaced, you will order a replacement CPU tray, and replace the entire tray.

Note

GPU slots are designed to accommodate FHFL, double-wide GPUs. When the server is configured with single-width GPUs, such as the NVIDIA RTX Pro 4500, you need to install a perforated filler panel (UCSC-PCIE-FH) to close the empty space next to the GPU. Perforated panels must be installed at a 1:1 ratio with each single-width GPU. To order the correct number of perforated panels, subtract the number of GPUs from 16. GPU mixing is not supported in the chassis, so the chassis will either contain all FHFL double-width GPUs plus solid filler panels, or all FHFL single-width GPUs plus perforated panels.
