Container Manager(SCM) 类似HDFS中的Block Manager，管理 Container, Pipelines 和 Datanode，为 Ozone Manager 提供Block 和 Container 的操作和信息。SCM也监听 Datanode 发来的心跳信息，作为Datanode manager的角色, 保证和维护集群所需的数据冗余级别。SCM 和 Ozone Client https://www.iteblog.com Block 组成的集合。在 Ozone 中， 数据是以 Container 的粒度进行副本复制的。Pipeline 来保证 Container 实现想要的副本数。SCM 中目前支持2种 Pipeline 方式实现多副本，单副本的 Standalone 模式和三副本的 Ratis 方式。Container 有2种状态，OPEN 和 CLOSED。当一个Container 为基本存储单元，维护每个 Container 内部的数据映射关系，定时向 SCM 发送心跳节点，汇报节点的信息，管理的 Container 的信息，Pipeline 的信息。当一个 Container Size 超过预定的大小 90% 时 或者写操作失败时，Datanode 会发送 Container Close 命令给 SCM，把 Container 的状态从 Open 转变成 Closed。或者当Pipeline

新的节点加⼊Ozone集群 II. 删除⼤量数据后 好处 III.充分利⽤集群资源 IV.均衡集群IO访问 实现 V. Balancer实现为SCM的⼦功能 VI.Container是数据迁移的最⼩单位， 只迁移CLOSE状态的Container VII.客户端发送命令给SCM，SCM负责 执⾏和控制整个流程 Ozone Manager DN1 Storage Container Manager Client
