-With a Ceph server, you can choose [Ceph RBD](https://kubernetes.io/docs/concepts/storage/storage-classes/#ceph-rbd) or [Ceph CSI](https://github.com/ceph/ceph-csi) as the underlying storage plugin. Ceph RBD is an in-tree storage plugin on Kubernetes, and Ceph CSI is a Container Storage Interface (CSI) driver for RBD, CephFS. 
+您可以选择 [Ceph RBD](https://kubernetes.io/zh/docs/concepts/storage/storage-classes/#ceph-rbd) 或 [Ceph CSI ](https://github.com/ceph/ceph-csi) 作为 Ceph 服务器的底层存储插件。Ceph RBD 是 Kubernetes 上的一个树内存储插件，Ceph 容器存储接口（CSI）是一个用于 RBD 和 CephFS 的驱动程序。
 
-###  Which plugin to select for Ceph 
+### Ceph 插件
 
-Ceph CSI RBD is the preferred choice if you work with **14.0.0 (Nautilus)+** Ceph cluster. Here are some reasons:
+如果你安装的是 Ceph v14.0.0（Nautilus）及以上版本，那么推荐您使用 Ceph CSI RBD。原因如下：
 
-- The in-tree plugin will be deprecated in the future.
-- Ceph RBD only works on Kubernetes with **hyperkube** images, and **hyperkube** images were 
-  [deprecated since Kubernetes 1.17](https://github.com/kubernetes/kubernetes/pull/85094).
-- Ceph CSI has more features such as cloning, expanding and snapshots.
+- 树内存储插件将会被弃用。
+- Ceph RBD 只适用于使用 hyperkube 镜像的 Kubernetes 集群，而 hyperkube 镜像
+ [从 Kubernetes 1.17 开始已被弃用](https://github.com/kubernetes/kubernetes/pull/85094)。
+- Ceph CSI 功能更丰富，如克隆，扩容和快照。
 
 ### Ceph CSI RBD
 
-Ceph-CSI needs to be installed on v1.14.0+ Kubernetes, and work with 14.0.0 (Nautilus)+ Ceph Cluster. 
-For details about compatibility, see [Ceph CSI Support Matrix](https://github.com/ceph/ceph-csi#support-matrix).

-The following is an example of KubeKey add-on configurations for Ceph CSI RBD installed by **Helm Charts**.
-As the StorageClass is not included in the chart, a StorageClass needs to be configured in the add-on config. 
+以下是 Helm Charts 安装的 Ceph CSI RBD 的 KubeKey 插件配置示例。由于 StorageClass 不包含在 chart 中，因此需要在插件中配置 StorageClass。

 ### Ceph RBD
 
-KubeKey will never use **hyperkube** images. Hence, in-tree Ceph RBD may not work on Kubernetes installed by KubeKey. However, if your Ceph cluster is lower than 14.0.0 which means Ceph CSI can't be used, [rbd provisioner](https://github.com/kubernetes-incubator/external-storage/tree/master/ceph/rbd) can be used as a substitute for Ceph RBD. Its format is the same with [in-tree Ceph RBD](https://kubernetes.io/docs/concepts/storage/storage-classes/#ceph-rbd). 
-The following is an example of KubeKey add-on configurations for rbd provisioner installed by **Helm Charts including a StorageClass**.
+Kubekey 没有使用 hyperkube 镜像。因此，树内 Ceph RBD 可能无法在使用 KubeKey 安装的 Kubernetes 上工作。如果你的 Ceph 集群版本低于 14.0.0，Ceph CSI 将不能使用，但是由于 [RBD](https://github.com/kubernetes-incubator/external-storage/tree/master/ceph/rbd) 格式和 Ceph RBD 相同，可以作为 Ceph RBD 的替代选项。下面是由 Helm Charts 安装的 RBD Provisioner 的 KubeKey 插件配置示例，其中包括 StorageClass。
