摘要： A mechanism is provided that aggregates data in a way that permits data to be deleted efficiently, while minimizing the overhead necessary to support bulk deletion of data. A request is received for automatic deletion of segments in a container and a waterline is determined for the container. A determination is made if at least one segment in the container falls below the waterline. Finally, in response to one segment falling below the waterline, the segment from the container is deleted. Each object has an associated creation time, initial retention value, and retention decay curve (also known as a retention curve). At any point, based on these values and the current time, the object's current retention value may be computed. The container system continually maintains a time-varying waterline: at any point, objects with a retention value below the waterline may be deleted.

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： 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： 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.

摘要： A failure recovery framework to be used in cooperative data stream processing is provided that can be used in a large-scale stream data analysis environment. Failure recovery supports a plurality of independent distributed sites, each having its own local administration and goals. The distributed sites cooperate in an inter-site back-up mechanism to provide for system recovery from a variety of failures within the system. Failure recovery is both automatic and timely through cooperation among sites. Back-up sites associated with a given primary site are identified. These sites are used to identify failures within the primary site including failures of applications running on the nodes of the primary site. The failed applications are reinstated on one or more nodes within the back-up sites using job management instances local to the back-up sites in combination with previously stored state information and data values for the failed applications. In additions to inter-site mechanisms, each one of the plurality of sites employs an intra-site back-up mechanism to handle failure recoveries within the site.
