红帽全球峰会19.2. 配置 Ceph Storage
director 提供了两种主要方法，用于将 Red Hat Ceph Storage 集成到 Overcloud 中。
- 使用自己的 Ceph Storage 集群创建 Overcloud
- director 能够在创建 Overcloud 期间创建 Ceph Storage 集群。director 会创建一组 Ceph Storage 节点，它使用 Ceph OSD 来存储数据。另外，director 在 Overcloud 的 Controller 节点上安装 Ceph Monitor 服务。这意味着，如果组织创建具有三个高可用性控制器节点的 Overcloud，Ceph Monitor 也变成高度可用的服务。有关更多信息，请参阅使用容器化 Red Hat Ceph 部署 Overcloud 指南。
- 将现有的 Ceph 存储集成到 Overcloud 中
- 如果您已经有一个现有的 Ceph Storage 集群，可以在 Overcloud 部署期间集成。这意味着您可以在 Overcloud 配置之外管理并扩展集群。有关更多信息，请参阅将 Overcloud 与现有 Red Hat Ceph 集群集成 指南。
