摘要： Methods and apparatus are described for a horizontally scalable high performance object storage architecture. Metadata are completely decoupled from object storage. Instead of file names, users are given a locator when the object is uploaded and committed. Users can store the locator along with their own metadata or embed it directly in the static content. Clients can choose which storage nodes to store data on based on dynamic measures of node performance. Since there is no coupling among storage servers, performance can scale horizontally by adding more nodes. The decoupling also allows the front end services and storage to scale independently. High service availability is achieved by object-level synchronous replication and having no single point of failure. Failed nodes are rebuilt using copies of data in other nodes without taking the cluster offline. In addition to the replication, the ability to add or remove nodes on-line reduces maintenance-related service downtime.
摘要翻译：对于水平可扩展的高性能对象存储架构描述了方法和装置。元数据完全脱离对象存储。而不是文件名，当对象被上传和提交时，给予用户一个定位器。用户可以将定位器与其自己的元数据一起存储，也可以将其直接嵌入到静态内容中。客户可以根据节点性能的动态度量，选择哪些存储节点存储数据。由于存储服务器之间没有耦合，所以性能可以通过添加更多节点来水平扩展。去耦还允许前端服务和存储独立扩展。通过对象级同步复制实现高服务可用性，并且没有单点故障。在不使群集脱机的情况下，使用其他节点中的数据副本重建失败的节点。除了复制之外，还可以在线添加或删除节点，从而减少维护相关的服务停机时间。
