Program revision compatibility in an object-oriented environment is provided operating between a first and a second program. The first program has a parent object with an initial group of fields and an inherited child object with an initial group of fields. In one embodiment, an expansion descriptor is established in the first program which provides a data storage location for data of a new field. The data of the new field is sent to the data storage location of the expansion descriptor and a child object identifier is associated with the data of the new field in the expansion descriptor. The expansion descriptor is sent to the second program along with object information of the child object corresponding to the initial group of fields. The second program recognizes the expansion descriptor and may update a corresponding child object of the second program regardless of whether the second program has been updated with the new field.

There is disclosed a client-server configuration including a peripheral device wherein multiple servers interface with both the client and the peripheral. Management software for determining the operating state of the peripheral, known as server agent software, is employed in the multiple servers under control of the client. In order to avoid conflicting information reflecting multiple operating states of the peripheral, a primary/secondary algorithm is used to enable the client to determine only one peripheral operating state while allowing each server to also verify its connectivity to the peripheral and to the client.

Some embodiments of the invention relate to selecting a data protection scheme, such as, for example, mirroring or RAID, for a content unit based on power-related metadata associated with the content unit. The data protection strategy selected for a content unit may impact the amount of power that a storage system consumes.

Information processing techniques are disclosed for managing knowledge across a distributed entity using predictive analysis. For example, a method comprises the following steps. At least a portion of the information is indicative of at least one of a previous expansion, a previous transfer and a previous leveraging of the knowledge attributable to the at least one distributed entity. A predictive analysis is performed on at least a portion of the obtained information to generate one or more recommendations for at least one of a future expansion, a future transfer and a future leveraging of the knowledge attributable to the at least one distributed entity.

A service window optimized system alert engine is disclosed for automated generation and delivery of alerts relating to detected conditions of a monitored system. The service window optimized system alert engine comprises a state monitor, a system configuration and history module, an alert generator, and an alert router. The state monitor is configured to send status data of the monitored system to the alert generator. The system configuration and history module provides information to the alert generator specifying an alert generation policy established for the monitored system. The alert generator is configured to process the status data from the state monitor in accordance with the alert generation policy specified by the system configuration and history module to generate at least one alert. The alert router is configured to determine optimal delivery characteristics for the generated alert and to deliver the alert in accordance with the optimal delivery characteristics.

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.

Information processing techniques for managing user discovery requests in a computing system such as a socially-aware data storage system. In one example, a method comprises the following steps. A user discovery request is sent from a first client to a socially-aware data storage system. The user discovery request comprises a social score computed for the first client. A list of other clients associated with the socially-aware data storage system is received at the first client from the socially-aware data storage system. The list of other clients is based on the social score computed for the first client.
摘要:
Described are techniques for user interface selection. A plurality of user interface sets is provided. Each of the plurality of user interface sets includes a plurality of user interfaces corresponding to a plurality of user levels of interaction. Each of the plurality of user levels of interaction is associated with a different level of abstraction with respect to processing performed in the data storage system for implementing a request. First user information associated with the user is provided. The first user information identifies one of said plurality of user levels for at least one of the plurality of user interface sets. A user interface is selected for display in connection with interactions with the user in accordance with the first user information. The selected user interface is displayed.
摘要:
One embodiment of the present invention is directed to providing a software layer that provides a Content Addressable Storage (CAS) capability in a computer system in which the content units are ultimately stored on a block I/O storage system. An application program may issue access requests to content units referring to them via a content address, and the software layer can convert such access requests to block I/O commands to be processed by the block I/O storage system. Thus, a CAS capability can be provided despite the absence of a storage system that provides such a capability natively.

One embodiment of the invention is directed to the containerization of content units that are accessed using an identifier. Applicants have appreciated that file systems sometimes impose limits on the number of files that may be stored therein that are too restrictive. Thus, in one embodiment, multiple content units may be stored in a single file, called a container file, in a file system. Each content unit may have an identifier associated with it. When an accessing entity requests access to a previously-stored content unit and provides the identifier for the content unit, the identifier may be used to locate the container file in which the content unit is stored.
