红帽全球峰会2.4. Data Warehouse（数据仓库）
Red Hat Virtualization Manager 包括一个全面的管理历史数据库，可供任何应用程序用来在数据中心、集群和主机级别提取一系列信息。安装数据仓库将创建 ovirt_engine_history 数据库，其中管理器配置为记录用于报告的信息。数据仓库组件必须与管理器设置一起安装和配置。
要计算使用 ovirt_engine_history 数据库所使用的空间和资源估算，请使用 RHV Manager History Database Size Calculator 工具。估计结果基于实体数量和您选择保留历史记录记录的时间长度。
