摘要： A system and method of offline annotation of future access are disclosed. According to one embodiment, a request is received at a storage system to read a portion of a file stored in the storage system. In response to the request, chunks of the file are cached in a cache memory of the storage system. In response to a request for cache space reclamation, the system then determines future request to the file based in part on a next access auxiliary table (NAAT) associated with the file, which was created prior to receiving the request to read and stored in a persistent storage location of the storage system. Based on the determination, the system evicts from the cache memory at least one chunk of a read unit (RU) whose next access is a furthest among the cached chunks.

摘要： Data objects of a file are cached in a cache memory of a storage system. An access sequence of the cached data objects is determined based on metadata of the file. In response to a request for cache space reclamation, a data object is evicted from the cache memory whose next access is a farthest amongst the cached data objects based on the access sequence of the data objects.

摘要： Data objects of a file are cached in a cache memory of a storage system, where the data objects of the file are accessed sequentially via access windows in a chain. It is estimated whether a next access of a data object of the file likely occurs in which of the access windows using respective bloom filters associated with the access windows. In response to a request for cache space reclamation, a data object is evicted from the cache memory that will be likely accessed in a farthest access window in the chain from a current access window based on the estimation.

摘要： A service model, integrated system, and method for enabling a service provider to deliver an integrated web hosting and content distribution service offering, which affords assured operational performance service levels, regardless of whether the customer's web site is served by the service provider's hosting center, the service provider's content distribution network (CDN), by a third party web host, or by a third party CDN. A monitoring system of the primary service provider receives detailed capacity and health statistics from any CDN under the operational control of the primary service provider, receives aggregate capacity and health statistics from other CDNs not under the operational control of the primary service provider. A redirection system then decides to which web host, content distribution network, or combination thereof, user requests for content are directed in order that operational performance service levels are maintained.

摘要： A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and potentially heterogeneous sites in a cooperative arrangement to process user-defined inquiries over dynamic, continuous streams of data. The system derives jobs from the inquiries and these jobs are executed on the various distributed sites by executing applications containing processing elements on these sites. Therefore, components of a given job can be executed simultaneously and in parallel on a plurality of sites within in the system. The sites associated with a given job execution have the need to share data, both primal and derived. A tunnel mechanism is provided that establishes tunnels between pairs of sites within the system. Each tunnel includes either a sink processing element on an originating site and a source processing element on a destination site or a gateway processing element on each site and a network connection between the sink and source processing elements. The sink and source processing elements are in communication with application processing elements on their respective sites and facilitate the exchange of data between these application processing elements. Tunnels can be establish on demand or in accordance with a prescribed plan and can be job specific of generic to any job executing on a given pair of sites.

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： Backup requirements of a new client and one or more existing clients stored in a first set of first storage units are determined. Data of the one or more existing clients is then migrated from the first set of storage units to a first storage unit that is selected from a second set of storage units based on a cost calculated using a cost function based on at least backup requirements of the new and existing clients. Subsequent data of the new client and the existing clients is stored in the first storage unit.

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. A method is provided to organize the distributed sites into a plurality of virtual organizations that can be further combined and virtualized into virtualized virtual organizations. These virtualized virtual organizations can also include additional distributed sites and existing virtualized virtual organizations and all members of a given virtualized virtual organization can share data and processing resources in order to process jobs on either a task-based or goal-based allocation mechanism. The virtualized virtual organization is created dynamically using ad-hoc collaborations among the members and is arranged in either a federated or cooperative architecture. Collaborations between members is either tightly-coupled or loosely coupled. Flexible management of resources is provided with resources being provided under exclusive control or based on best-effort access.
