Overview of the Cisco UCS C885A M8 Rack Server
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, the server offers a choice of eight GPUs of the following types:
-
NVIDIA® H100 SXM or NVIDIA® H200 Server PCI Express Module (SXM) GPUs. SXM is a socket-based GPU interconnect method used by NVIDIA GPUs.
-
AMD MI300X 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 also supports one NVIDIA Bluefield-3 B3220 DPU to scale AI model training across a cluster of dense-GPU servers. Up to eight NVIDIA ConnectX-7 or Bluefield-3 B3140H SuperNIC are supported for east-west traffic between GPUs.
Introduction
The Cisco Baseboard Management Controller (Cisco BMC) web GUI is HTML5 based and added security with SSL (HTTPS). It helps you manage the Cisco UCS C885A M8 Rack Server using the following options:
Hardware and Component Management
The Inventory feature enables administrators to record hardware devices and components on each server, such as central processing units (CPUs), memory modules, hard drives, network cards, and more.
Status and Checks
The Inventory feature also provides status and checks for hardware and software devices. This information can include device health status, temperature, voltage, connection status, and more.
Supported Platforms
The following servers are supported in 1.0.0.240001 and later releases:

Upgrade and Downgrade Guidelines
Upgrade and Downgrade Guidelines for Release 1.0.1.250002
Once you upgrade to release 1.0.1.250002, you cannot downgrade to any earlier release.
Firmware Files
 Note |
Always upgrade all the components BIOS, BMC, and FPGA. Do not upgrade individual components (only BIOS or only BMC), since this could lead to unexpected behavior. If the BIOS and the BMC versions are from different container releases, it could result in unexpected behavior. |

CSCwn89077 |
Due to a configuration issue, some servers may experience limited network accessibility restricted to the same subnet. To resolve this, a MAC address configuration update is required. This affects environments with static configuration settings. |
To recover the server, configure the MAC address as 00-00-00-00-00-00. |

CSCwn86753 |
A standby power issue affects the OCP adapter on the eth1 interface, causing BMC network connectivity to go down when the host is powered off. This impacts systems using the shared-NIC concept for the eth1 interface. |
There is no known workaround. |

Update GPU firmware using the host-based utility provided by the GPU manufacturer. |

|
CSCwo76759 |
Cisco BMC is unable to dynamically re-learn the network gateway MAC address when the default gateway MAC is not set or has changed. As a result, while it can communicate within the same subnet, it cannot respond to traffic from a different subnet unless the default gateway MAC is manually configured. This may cause the Cisco BMC to become unreachable outside the subnet when switching between static environments with different subnets. |
Using any host in same subnet set the default getway MAC address: $ipmitool -H <BMC IP> -U root -P <password> -I lanplus lan set 1 defgw macaddr <MAC address of the getway> |
