摘要： The method and apparatus collect file recipes from deduplicated data storage systems, the file recipes consist of a list of fingerprints of data chunks of a file. Detailed meta-data for each unique data chunk is also collected. In an offline process, research and analysis can be performed on either the meta-data itself or on a reconstruction of a full trace of meta-data constructed by matching recipe fingerprints to the corresponding meta-data. The method and system can generate the full meta-data trace efficiently in an on-line or off-line process. Typical deduplicated storage systems achieve 10× or higher deduplication rates, and the meta-data collection is faster than processing all of the original files and produces compact meta-data that is smaller to store.

摘要： A system and method for optimizing a storage system to support short data object lifetimes and highly utilized storage space are provided. With the system and method, data objects are clustered based on when they are anticipated to be deleted. When an application stores data, the application provides an indicator of the expected lifetime of the data, which may be a retention value, a relative priority of the data object, or the like. Data objects having similar expected lifetimes are clustered together in common data structures so that clusters of objects may be deleted efficiently in a single operation. Expected lifetimes may be changed by applications automatically. The system automatically determines how to handle these changes in expected lifetime using one or more of copying the data object, reclassifying the container in which the data object is held, and ignoring the change in expected lifetime for a time to investigate further changes in expected lifetime of other data objects.
摘要翻译：提供一种用于优化存储系统以支持短数据对象寿命和高度利用的存储空间的系统和方法。使用系统和方法，数据对象将基于何时被预先删除而进行聚类。当应用程序存储数据时，应用程序提供数据的预期寿命的指示符，其可以是保留值，数据对象的相对优先级等。具有相似的预期寿命的数据对象在公共数据结构中聚集在一起，使得可以在单个操作中有效地删除对象簇。预期的使用寿命可能会自动更改。系统自动确定如何使用一个或多个复制数据对象来重新分类数据对象所在的容器，并忽略预期生命周期的变化，以调查预期生命周期的进一步变化，以期如何处理预期生命周期中的这些更改的其他数据对象。

摘要： A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and possibly heterogeneous sites in a cooperative arrangement to process user-defined job requests over dynamic, continuous streams of data. The sites negotiate peering relationships to share data and processing resources to handle the submitted job requests. These peering relationships can be cooperative or federated and can be expressed using common interest policies. Each site within the system runs an instance of a system architecture for processing job requests and is therefore a self-contained, fully functional instance of the cooperative data stream processing system.

摘要： The invention provides for customized “what's new” lists for users of shared lists of tracked resources. Identifying information, such as cookies, and state information are used to personalize a shared “what's new” list, so that changes to a document which a particular user has viewed are indicated automatically based on the last time that user viewed the document. Thus, the user is notified of the set of changes that have taken place since the user last viewed a particular set of documents. For any particular document, only the changes which have occurred since the user last viewed that document are used to form the “what's new” list and to view the changes if the user so chooses. Additionally, a user can select multiple collections of documents into a single notification system and exclude particular documents or augment the collection to personalize the resources tracked for that user.
摘要翻译：本发明为追踪资源共享列表的用户提供定制的“新增功能”列表。使用识别信息（如Cookie和状态信息）来个性化共享的“新功能”列表，以便根据用户上次浏览文档的最后时间自动显示特定用户所查看的文档的更改。因此，用户被通知自用户上次查看特定文档集合以来发生的一组变化。对于任何特定文档，只有用户上次查看该文档后发生的更改被用于形成“新功能”列表，并在用户选择时查看更改。此外，用户可以将多个文档集合选择到单个通知系统中，并排除特定文档或扩充该集合以个性化为该用户跟踪的资源。

摘要： A system and method for reducing access latency to stable storage are described. A technique referred to as fault trickling is used to improve access latency to stable storage such as flash memory. In particular, data requests from a central processing unit are preferentially satisfied by a memory management unit providing access to a main memory. When the requested data does not reside in the main memory, however, the memory management unit satisfies the request by providing direct fine-grain access to the flash memory. In addition, concurrently with satisfying the data request directly from the flash memory, a block transfer is initiated from the flash memory to the main memory. Once the block transfer is completed, a memory map, such as an address translation table, is updated to indicate that the data now resides in the more convenient source of data--the main memory. Accordingly, subsequent data requests, for that or proximately located data, can be satisfied by accessing the main memory.
摘要翻译：描述用于减少对稳定存储的访问延迟的系统和方法。被称为故障滴流的技术被用于改善诸如闪存之类的稳定存储的访问延迟。特别地，来自中央处理单元的数据请求优先地由提供对主存储器的访问的存储器管理单元来满足。然而，当请求的数据不在主存储器中时，存储器管理单元通过向闪存提供直接的细粒度访问来满足该请求。另外，与从闪速存储器直接满足数据请求同时，从闪速存储器向主存储器发起块传送。一旦块传输完成，更新存储器映射，例如地址转换表，以指示数据现在位于更方便的数据源 - 主存储器中。因此，可以通过访问主存储器来满足针对该位置或近似位置的数据的后续数据请求。

摘要： A system and method for protecting streams in a mixed infrastructure includes determining processing elements that are to access a data stream in a stream processing environment and determining a security level for each processing element. Keys are generated per stream per processing element in accordance with the security level. The keys are associated with processing elements in an access control list in a location accessible by producing and consuming processing elements. The stream is decrypted for processing using keys released upon authenticating processing elements in accordance with the access control list. At security boundaries, the stream is re-encrypted in accordance with a next processing element.

摘要： A method for storing data in a data storage system by partitioning the data into a plurality of data chunks and generating representative data for each of the plurality of chunks by applying a predetermined algorithm to each chunk of the plurality of chunks. Subsequently, the representative data is compared and sorted. Representative data for base data chunks and representative data for other data chunks that can be stored relative to the base data chunks are identified by evaluating the sorted set of representative data. Finally, each of the other data chunks identified as those that can be stored relative to a base data chunk are stored in the data storage system as the difference between the data chunk and a base data chunk.
