摘要： A file is striped across multiple filers, file servers or other devices, to create a sparsely striped multi-component file. Each filer stores one sparse component. In particular, each component physically stores only those stripes allocated to that component. The other stripes are represented as holes. Thus, instead of contiguously packing each component's stripes at the block level, each component is a file having the same logical structure. A component of a sparsely striped multi-component file can be easily converted to a mirror by filling in its holes. Similarly, a mirror can be easily converted to one component of a sparsely striped multi-component file by removing or ignoring it unallocated stripes. In either case, the layout or logical of the component does not need to be reconfigured.
摘要翻译：一个文件在多个文件管理器，文件服务器或其他设备上分条，以创建一个稀疏条纹的多组件文件。每个文件管理器存储一个稀疏组件。特别地，每个组件仅物理地存储分配给该组件的那些条带。其他条纹表示为孔。因此，代替在块级别连续地打包每个组件的条带，每个组件是具有相同逻辑结构的文件。稀疏条纹的多组分文件的一个组件可以通过填充其孔洞轻松地转换成镜像。类似地，通过删除或忽略它未分配的条纹，可以容易地将镜像转换为稀疏条纹的多组分文件的一个组件。在这两种情况下，组件的布局或逻辑不需要重新配置。

摘要： A system and method for facilitating a consistent point-in-time copy (PITC). A data provider offers access to data by one or more clients. A client issues a PITC request for a set of data to the data provider, or the provider initiates its own request. The data provider instructs one or more clients, particularly clients accessing the set of data, to flush any pending updates. The clients acknowledge the flush request, flush their data, and notify the data provider when their flushes are complete. Post-consistency updates are deferred (e.g., using a write-aside buffer). If a client fails to acknowledge the flush request or notify of flush completion, the data provider may abort the PITC or continue because the data may not be consistent or consistency may not be assured. If not aborted, the PITC may be marked to indicate that it is incomplete.
摘要翻译：一种用于促进一致的时间点复制（PITC）的系统和方法。数据提供者提供一个或多个客户端对数据的访问。客户端向数据提供者发出一组数据的PITC请求，或提供者发起自己的请求。数据提供者指示一个或多个客户端，特别是访问数据集的客户端，以刷新任何未完成的更新。客户端确认刷新请求，刷新其数据，并在其刷新完成时通知数据提供者。后续一致性更新被推迟（例如，使用写缓冲区）。如果客户端无法确认刷新请求或通知刷新完成，则数据提供者可能会中止PITC或继续，因为数据可能不一致或一致性可能无法保证。如果没有中止，PITC可能被标记为表示它是不完整的。
