Overview

The Cisco UCS C885A M8 Rack Server is a dense-GPU server designed to deliver massive, scalable accelerated compute capabilities to address the most demanding AI workloads, including deep learning/Large Language Model (LLM) training, model fine-tuning, large model inferencing, and Retrieval-Augmented Generation (RAG).

To deliver massive accelerated compute performance in a single server, each server supports a maximum of eight GPUs of the following types:

  • NVIDIA® H100 Tensor Core or NVIDIA® H200 Tensor Core Server PCI Express Module (SXM) GPUs. SXM is a socket-based GPU interconnect method used by NVIDIA GPUs.

  • AMD Instinct™ MI300X and AMD Instinct™ MI350X OCP Accelerator Model (OAM) GPUs. OAM is an Open Compute GPU interconnect standard that avoids GPU vendor lock in.

For north-south traffic, the server supports up to two NVIDIA BlueField-3 B3220 DPUs or up to two NVIDIA ConnectX-7 NICs.

For east-west traffic, the server supports up to eight NVIDIA ConnectX-7s, AMD Pensando™ Pollara 400 AI NICs, or BlueField-3 B3140H SuperNICs for GPUs enabling AI model training across a cluster of dense-GPU servers.

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

External Features

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

  • CPU tray

  • HGBBU Tray

  • Power Tray

Each tray has a guide rail on each side of the chassis interior so that each tray can slide into and out of the chassis easily. Trays are keyed so that they cannot be installed the wrong way. Each tray has different physical dimensions from the others, so trays cannot be inserted into an incorrect location in the chassis.

CPU Tray

The CPU Tray contains the compute and network functions of the server.

Figure 3. CPU Tray

Item

Description

1

Network connectivity slots for north-south traffic support one or two NVIDIA Bluefield-3 B3220 DPUs or NVIDIA ConnectX-7 NICs for connectivity to upstream or downstream peer devices. As an option, slot 15 can support a Boot Optimized RAID controller.

2

Network connectivity slots for east-west traffic support up to eight NVIDIA Bluefield-3 B3140H SuperNICs , ConnectX-7 NICs, or AMD Pensando™ Pollara 400 AI NICs for GPU-to-GPU communication.

3

CPU Tray Redundant Power Supply Units. Two 2700 Watt PSUs are supported with 1+1 PSU redundancy. The minimum number of PSUs for the CPU tray is one, but with only one PSU, the server might throttle down traffic. With only one CPU, no fault tolerance is available.

4

One OCP 3.0 PCIe Gen 5 x8 NIC that features two 10G RJ45 ports for additional network connectivity to peer devices. This NIC can offer management connectivity for host management traffic.

5

One OCP 3.0 to Dual M.2 adapter card

6

One Data Center Secure Control Module (DC-SCM) based on the Open Compute 2.0 standard. This module is the default primary interface for network management.

DC-SCM Module

The DC-SCM module is supported on the CPU Tray. The module provides an interface to the server, and enables enforcing a common, robust security module across the servers and its connected peers that support the security model. By default, the DC-SCM module is the primary management interface for the server, but the OCP NIC can also be used for the management interface if desired.

Caution

 

We recommend using a mini-DP to VGA adapter for video output. If an external adapter is needed (for example, DP-to-VGA, DP-to-HDMI, or DP-to-DVI) please use an active type adapter only. This module does not support a DP++ type adapter.

Cisco M.2 NVMe BOOT RAID Controller

The server supports one internal boot-optimized RAID card, the Cisco M.2 NVMe BOOT RAID Controller (UCS-M2-NVRAID).This card is a standard half-height, half-length PCIe x8 NVMe RAID adapter card, which features two 960 GB NVMe M.2 SSDs with RAID 0/1 functionality.

  • The card features host interface support of PCIe Gen4 x8, and for each M.2, up to PCIe Gen4 x4

  • Each M.2 NVMe SSD can be either 110 mm and 80mm in length.

  • Each M.2 NVMe SSD has 960 GB of storage capacity.

  • Each SSD is uniquely numbered:

    • Drive 251 is the SSD at the "top" of the module. This drive is located closest to the right-angle bend in the module faceplate.

    • Drive 252 is the SSD at the "bottom" of the module. This drive is located closest to the golden fingers connectors that insert into the PCIe socket.

The card is a boot-optimized RAID card, so it controls striping and mirroring (RAID 0/1) of data for server boot up, OS loading, and logging. Because the card is boot-optimized, it does not control user data I/O, such as reads and writes to the server’s SAS and NVMe storage drives.

The card installs into slot 15 as a hardware option but is not a field-replaceable unit (FRU). If you want the Cisco M.2 NVMe BOOT RAID Controller installed in your server, it will be pre-installed in a new CPU Tray, which is a FRU. Contact Cisco to order a new CPU Tray and specify all modules and 12V PSUs installed on the CPU Tray so that you can receive an exact replacement.

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.

  • Mainboard

  • Power distribution board

  • Mid-plane board

  • HIB host interface Board

  • FIO board

  • CEM 8X BB board

  • LCEM Riser

  • RCEM Riser

  • Fan extension board

  • Fan interposer board

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

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.

DIMM Slot Locations

The server contains two CPUs (0 and 1) each with two banks of six DIMMs channels. CPU 0 has DIMM channels A through F and G though L for a total of 12 DIMMs.

CPU 1 has DIMM channels A through F and G through L for a total of 12 DIMMs.

The individual DIMMs are not serviceable.

Figure 24. DIMM Slot Locations

DIMM slots are labeled sequentially (A through L) for each CPU. Use the following recommendations for memory channels per configuration.

Memory Module Population Rules

All DIMMs must be DDR5 DIMMs. 16GB, 24GB, and 32GB density DRAMs are supported. The following DIMM types and bit widths are supported:

  • DIMM capacities from 16GB to 1TB depending on type and configuration

  • RDIMM: 1Rx8, 2Rx8, 1Rx4, and 2Rx4

  • 3DS RDIMM: 2Rx4 2H and 2Rx4 4H o 2Rx4 8H, which support capacities of 512GB/768GB/1024GB for 16Gb/24Gb/32Gb die densities, respectively.

  • 80b x4, 80b x8, and 72b x4 ECC support

  • 80b x4 AMDC, 80b x8 and 72b x4 optimized Bounded Fault ECC DRAM support

The following general population restrictions apply:

  • Do not mix DIMM module types within a memory channel. All must be RDIMM or RDIMM 3DS module types with the same ECC configuration.

  • Do not mix x4 and x8 DIMMs within a memory channel.

  • Do not mix 3DS and non-3DS memory modules in a 2DPC system.

General population recommendations:

  • Mixing DIMMs of different ranks (i.e., 1R, 2R, 3DS) across memory controller channels will change or disable the chip select interleaving feature and may have performance impact. Mixing DIMMs of different ranks within a memory controller channel is not supported.

  • Mixing DIMMs from different manufacturers is supported across memory controller channels, but is not supported within a memory controller channel.

  • Mixing DIMMs of different density (i.e., 16Gb, 24Gb, and 32Gb DRAMs) within a memory controller channel is not supported. Mixing DIMM density across memory controller channels is supported, though a performance impact may be noted. Platform developers are expected to validate configurations that mix DIMM density across memory controller channels.

Redundant PSU Locations

The server has PSUs rated at 12V and 54V. Different PSU types support different power redundancy. Full grid redundancy is not supported.

Description

12V redundant power supply units, 2 (left and right)

54V redundant power supply units

Support for PSU Redundancy and Continuous Operation

The system includes eight power supply units (PSU) configured for 12V CRPS 1+1 and 54V PSU 4+2 redundancy. Refer to the following additional considerations:

  • For 12V CRPS 1+1

    • If one PSU fails, troubleshoot the cause and replace the failing PSU immediately. If one PSU fails, the server continues to operate at full performance, and the PSU statues/health LED glows solid amber.

  • For 54V AC PSU 4+2

    • If only two 54V PSUs are installed, the system can power on and operate without the GPU Tray installed.


      Note

      This configuration is not a standard runtime config. It is used for system debug purposes only.

    • If only three 54V AC PSUs are installed, the server operates, but with performance reduced performance (power capping every GPU to 60%).

    • If four or more 54V AC PSUs are installed - the server operates at full performance.
