摘要:
A system and method store information to a sequential storage media such that storage space occupied-by data deemed obsolete may be reclaimed. Information may be written to the storage media as sequential data sets with each data set including a catalog describing the information in the data set. A reclamation catalog identifies the obsolete data stored on the media and is written to the media. A generation number on the storage media may indicate whether the storage media has been reclaimed. A reclamation process transfers data from the source media (e.g., the tape media that includes obsolete data) to a destination media (e.g., a blank tape) while excluding the obsolete data identified in the reclamation catalog. The reclamation process may read a catalog stored on the source media that describes the data stored on the source media. The reclamation process then modifies that catalog by the information stored in the reclamation catalog to create a unified catalog. The unified catalog identifies which of the data stored on the source media is to be copied to the destination media. The reclamation process then copies the data identified in the unified catalog to the destination media. The reclamation process may additionally increment the generation number to indicate that the storage media has been reclaimed.

A mini-cloud system has been described to enable subscription or service model for computing infrastructure, software, and digital content. The mini-cloud system works as a pipeline for information delivery connecting end user, infrastructure provider, content provider, and retailer offering automatic provisioning of infrastructure, content life cycle management, automatic upgrade, servicing, and license managements based on subscription model. Mini-cloud system uses a subscription management component and virtualization host to back computing environment, then adds routing component to connect to back-end cloud infrastructure along with a digital content delivery framework. The system allows a user to subscribe in a computing environment, preferred software applications, and digital content like movie and pay like a monthly utility bill.

Described herein is a technology facilitating the operation of non-native program modules within a native computing platform. This technology provides a mechanism for aligning—as necessary—parameters of data structures so that program modules or operating systems of different paradigms may use them. The data of parameters of data structures is aligned to match the native paradigm. Typically, such data structures are shared by non-native program modules and the native operating system (or other program modules). It is aligned so that data—that would otherwise be non-aligned and performance hindering—is quickly and easily accessible by the native platform. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

A mini-cloud system has been described to enable subscription or service model for computing infrastructure, software and Digital content. The mini-cloud system work as a pipe line for information delivery connecting end user, infrastructure provider, content provider, and retailer offering automatic provisioning of infrastructure, content lifecycle management, automatic upgrade, servicing, license managements based on subscription model. Mini-cloud system uses a subscription management component, virtualization host to back computing environment, then add routing component to connect to backend cloud infrastructure along with a digital content delivery framework. The system allow a user to subscribe a computing environment, preferred software applications, and digital content like move and pay a monthly utility bill.
摘要:
When using a common configuration data structure (e.g., “registry”), the access redirector and entry reflector promotes compatibility and interoperability between differing versions of program modules. The access redirector redirects selected accesses to storage locations (i.e., “nodes”) of a common configuration data structure. The selected accesses are redirected to another node. This redirection stores configuration information for differing versions of program modules at different nodes. However, the differing versions are unaware that they are accessing different nodes. As configuration information in a node is changed, the entry reflector may copy selected portions of such changed information into its associated “reflected” node and vice versa. This reflection allows associated “reflected” nodes to share relevant configuration information that promotes interoperability.

This invention presents a novel way to create a mega data center utilizing unused spare capacity in residential mini-cloud host devices. The host device is implemented using a novel approach in this invention. Part of the host devices is used to support residential user's home computing need. Unused capacity is then exposed to a subscription system that can lease that capacity back to other users in need. The system effectively creates an abstraction of a mega data center connecting millions of residential host devices interconnected to each other. The system provides similar infrastructure a data center provides with a minimal physical centralized infrastructure presence.

A method for redirecting, to a second machine, without user intervention, a request for access to a folder on a first machine, the request made by a resource executing within a remote access session on the first machine, includes receiving, by a component on a first machine, folder mapping information associated with a folder provided by a shell namespace on a second machine. The component intercepts a request by a resource executing on the first machine for access to file system data on the first machine. The component redirects the request to the second machine responsive to the received folder mapping information.
摘要:
A system, a method and a program product provide access to variable-length data segments on a sequential access storage medium using an iterative search for a specified data offset based on estimates of media offsets. The data is recorded in variable-length data segments aligned to predetermined alignment intervals. Each data segment has a predetermined signature field to identify the header of each data segment. Session data recorded on the medium so as to prevent session data that matches the signature field from being aligned with the predetermined alignment interval. Approximate or default parameters for data segment size are used for each estimate and are updated with each iteration based on actual data derived from data segment headers on the medium.
