映射 ：ring（环） 映射到硬盘
-
容器 在容器里面创建对象
-
对象 文件就是对象
-
账户 权限
ring文件 保存到硬盘
-
account.ring.gz 账户
-
container.ring.gz 容器
-
object.ring.gz 对象
保存到硬盘里的目录，这个目录为zone /srv/node/swiftloopback/ 挂载点 必须放在/srv/node/目录下
-
zone1
-
zone2 两个相同，备份
packstack方式安装完成后，上传一个文件，只在硬盘里保留一份
对象先映射到 虚拟节点/分区partition 2^n 再映射到zone
目的：减少数据的迁移量
swift服务
1 一致性服务 consisteny server
-
auditor 定期扫描,如果出现问题，就把有问题的文件放隔离区
-
replicate 从另外的zone复制相同的文件过来，实现数据同步
-
update 如果replicate失效了，那么等段时间再试
2 代维服务proxy server
接受用户发送过来的请求，比如上传、删除等请求
3 存储服务
容器服务器 container server
对象服务器 object server
账户服务器 acount server
