SXM (Server PCI Express Module) [1] is a high bandwidth socket solution for connecting Nvidia Compute Accelerators to a system. Each generation of Nvidia Tesla since the P100 models, the DGX computer series and the HGX boards come with an SXM socket type that realizes high bandwidth, power delivery and more for the matching GPU daughter cards.

2024年11月4日 · 为了进一步促进OAI的生态建立， OCP-OAI 小组在OAM的基础上统一了AI加速卡基板OAI-UBB（Universal Baseboard）设计规范。 规范以8张OAM为一个整体，定义了8xOAM的Baseboard的主机接口、供电方式、散热方式、管理接口、卡间互连拓扑、Scale Out方式，这里就不展开了，感兴趣的朋友可以查阅相关资料。 OAM GPU举例：下图是AMD的八卡OAM的GPU产品，通过1卡到7卡互联最多可实现双向互联带宽896GB/s（计算方式 …

SXM 是一种高带宽Socke (接口)解决方案，将NVIDIA计算加速器 (也就是NVIDIA的GPU，销售策略下也称为Compute Accelerator，以区别于CPU)连接到系统中。 从P100型号以来每一代NVIDIA数据中心GPU (Tesla, DGX compute系列 和 HGX系列) 主板都有SXM插座类型，可以实现高带宽、功率传输等，用于匹配的GPU紫卡: SXM Socket 的特定型号产品逗比PCIe同代产品具有更高的GPU性能: 配置更高的GPU Memory并且具备更大的GPU Memory Bandwidth.

The board has two counterrotating server-grade fans, an air shroud, and a solid aluminum backing plate to which a GPU is screwed. A few LEDs, an MCU, a DIP switch array, a few connections (including mini USB and JTAG), and two temperature sensors for the inlet and exhaust air are also present.

按照本节中的说明安装 SXM GPU 板。 安装 HGX A100 80GB 500W 4-GPU 板时，如果环境温度高于 30°C，则系统可能会指示 GPU 进入功率紧急降低状态，GPU 性能也会受到影响。 必须由经过培训的技术人员卸下和安装此组件。 请勿 在未经过相应培训的情况下执行拆卸或安装工作。 务必准备好酒精清洁垫。 请阅读 安装准则 和 安全检查核对表 以确保工作时的安全。 从包装盒中取出新的 GPU 板时，请用两只手抓住 SXM GPU 板 的长边。 图 1. 从包装盒中取出 SXM GPU …

Follow instructions in this section to install the SXM GPU board. When the HGX A100 80GB 500W 4-GPU Board is installed and if the ambient temperature is above 30°C, the GPUs may …

Those Dell C4130 and C4140 GPU servers that come equipped with SXM2 GPUs use an interposer board to connect these GPUs to CPUs, either via a PCIE PLX switch (SXM2 board, Dell p/n 0CTHR / 96PWG) or directly (Dell p/n 852X8).

2024年9月5日 · Dell NVLink SXM2 Board for C4140 C4130 96PWG SXM, NEW, IN STOCK, 5 Year Warranty

The GPU SXM2 board has four PCIe3.0 x16 PCIe slots to support low-profile expansion cards in the front of the chassis. A direct connection from the GPUs to an external high-speed interface is provided through a PCIe switch to an x16 slot in the front of the GPU tray.
