Disk Pool Manager（磁盘池管理器）系统是一种用于网格存储的多协议可扩展技术，支持大约130个站点，总共大约90 PB的在线存储。
该系统最近完成了过去几年宣布的开发阶段，将其核心组件（DOME：磁盘操作管理引擎）整合为一个功能齐全的高性能引擎，也可以与标准Web客户端一起操作，并使用一个完整的基于REST的协议。
除了性能上的总体改进和全面的管理命令行界面外，这一里程碑还带来了自动磁盘服务器状态检测和用于部署实验性磁盘缓存的易失性池等功能。
在这篇文章中，我们还讨论了对历史上的SRM组件（也包括对Globus工具包的依赖）的支持的结束，这些组件的部署现在只与SRM协议的使用相关联，因此当站点不再需要这些组件时，可以将其删除。
The DPM (Disk Pool Manager) system is a multiprotocol scalable technology for Grid storage that supports about 130 sites for a total of about 90 Petabytes online.
The system has recently completed the development phase that had been announced in the past years, which consolidates its core component (DOME: Disk Operations Management Engine) as a full-featured high performance engine that can also be operated with standardWeb clients and uses a fully documented REST-based protocol.
Together with a general improvement on performance and with a comprehensive administration command-line interface, this milestone also brings back features like the automatic disk server status detection and the volatile pools for deploying experimental disk caches.
In this contribution we also discuss the end of support for the historical DPM components (that also include a dependency on the Globus toolkit), whose deployment is now only linked to the usage of the SRM protocols, hence can be uninstalled when these are not needed any more by the site.
