摘要： A system and method are provided for retention of data on a storage system. An application program provides the storage system with data to be stored on the storage system. The application program also provides the storage system with a retention period that indicates a period of time for which the data may not be deleted. When the storage system receives a request to delete the data, it first evaluates the retention period associated with that data to determine if the retention period has expired. If the retention period has not expired, the storage system denies the request to delete the data.
摘要翻译：提供了一种用于将数据保存在存储系统上的系统和方法。应用程序向存储系统提供要存储在存储系统上的数据。应用程序还为存储系统提供了保留期限，指示数据可能不被删除的时间段。当存储系统接收到删除数据的请求时，它首先评估与该数据相关联的保留期，以确定保留期是否已过期。如果保留期没有过期，存储系统将拒绝删除数据的请求。

摘要： One embodiment is a system for locating content on a storage system, in which the storage system provides a location hint to the host of where the data is physically stored, which the host can resubmit with future access requests. In another embodiment, an index that maps content addresses to physical storage locations is cached on the storage system. In yet another embodiment, intrinsic locations are used to select a storage location for newly written data based on an address of the data. In a further embodiment, units of data that are stored at approximately the same time having location index entries that are proximate in the index.

摘要： One embodiment is directed to the deletion of content units from a storage system. When a content unit is deleted, a reflection may be created and stored on the storage system. The reflection identifies the deleted content unit and may include additional information, such as a portion of the content of the content unit and audit information regarding the deletion of the content unit.

摘要： A environment and method are provided for increasing the storage capacity of a data storage environment. Additional storage clusters may be added to the storage environment without affecting the performance of each individual storage cluster. When data is written to the storage environment, a selection may be made as to which storage cluster is to store the data. When data is read from the storage environment, it may be determined which storage cluster stores the data and the data may be retrieved from that storage cluster.

摘要： One embodiment is directed to a method of segregating one or more content addressable storage systems into a plurality of virtual pools. The virtual pools can be allocated to different content sources and/or can be assigned to different storage system capabilities. Another embodiment is directed to transmitting with an input/output request for a content unit information specifying at least one storage capability to be applied to the content unit, and/or receiving such an I/O and implementing the specified storage system capabilities. Another embodiment is directed to extracting from an I/O request from a source information relating to an impact of the I/O on at least one characteristic of the content units stored on a CAS system from the source. Another embodiment is directed to storing information for content identifying the source and/or reading information associated with a stored content unit and determining based at least in part thereon, at least one characteristic of the content units stored from a source.
摘要翻译：一个实施例涉及将一个或多个内容可寻址存储系统分离成多个虚拟池的方法。可以将虚拟池分配给不同的内容源和/或可以分配给不同的存储系统功能。另一个实施例涉及用于向内容单元发送指定要应用于内容单元的至少一个存储能力的信息的输入/输出请求，和/或接收这样的I / O并实现指定的存储系统能力。另一个实施例涉及从I / O请求中提取与来自源的存储在CAS系统上的内容单元的至少一个特性相关的I / O影响的源信息。另一个实施例涉及存储用于识别与存储的内容单元相关联的源和/或读取信息的内容的信息，并且至少部分地确定从源存储的内容单元的至少一个特征。
