# 存储集成概述

本指南将包含在将您期望的底层存储系统和Alluxio一起运行的通常先决条件。要学习如何配置每一个单独的存储系统和Alluxio运行，请查看它们各自的页面。 参考[配置挂载点](https://documentation.alluxio.io/ee-ai-cn/ai-3.3/ufs/pages/s3w56GJIUjH2RGoSatZG#配置-ufs) 以了解将存储挂载到Alluxio的命名空间中的命令。

## 先决条件

为了准备使用您选择的存储系统与Alluxio，请确保在开始配置Alluxio到您的底层存储系统之前，您拥有所有所需的位置、凭据和附加属性。

对于本指南的目的，以下是占位符。
