Abstract: The present invention is based on a regulation circuit (200a, 200b) for making available a constant current supply on the basis of a transformer principle, in which there flows through the luminescent diodes (D1, . . . ,DN) a triangular a.c. current (ID) varying periodically around a d.c. current value. With this method it is afforded by means of a circuitry provision that both the charging and also the discharging current (IL1) of an inductive reactance (XL1) connected in series to the luminescent diodes (D1, . . . ,DN), functioning as a storage choke (L1) for filtering of mains harmonics, flows as diode current (ID) through the luminescent diodes (D1, . . . ,DN). The advantage of this method consists in a significant reduction of the overall power loss (PV, ges) of the LED illumination module (100).

Abstract: There is provided a file server which is capable of suppressing power consumption of a storage apparatus. When a file sharing program receives a file access from a client, the program makes reference to a mapping table. Then, the program addresses the access to the target file in the volume of a RAID group in which the target file is stored. A coupling-request reception program memorizes a coupling time for each user into a coupling history table. A grouping program applies a grouping to users whose coupling time-zones are similar to each other. A data transfer program transfers, into the same RAID group, data of the files associated with the grouped users, thereby collecting the data of the files into the same RAID group. On account of this, the time-zone during which no access is made to the RAID group (i.e., non-coupling time-zone) can be made longer. Accordingly, a spin-up/down request program makes a spin-down request to the RAID group in the non-coupling time-zone.

Abstract: The management burden of a replication administrator is alleviated and the monitoring burden is reduced in a storage system. In a large-scale storage system configured across a plurality of sites, a management computer managing the storage system collects configuration information of a volume group such as the copy pair status information from a host computer of the respective sites including a primary site and a remote site, and analyzes the collected information. When a failure or a disaster occurs and the primary site and the remote site are switched and the management computer detects a change in the configuration of the volume group, and appropriate switches the monitoring configuration upon determining the configuration of the detected change.

Abstract: To generate appendices which uniquely reference an object geographically, a tree of possible paths is generated. The paths are evaluated in accordance with predefined criteria, which are suited for use as termination criteria, at the time the paths are formed. Of the remaining paths, at least that one is coded as an appendix which best fulfills at least one of the criteria.

Abstract: The invention relates to a system and a method for automated transfer and subsequent evaluation of the quality of mass data of a technical process or a technical project in a standardized environment (70) of one or more data processing devices with an assignment module (20) for allocating the mass data from one or more data sources (10) to structure elements in the standardized environment of the data processing device (70) and for generating a defined mapping of the mass data to be read in.

Abstract: An apparatus and method optimize a query in a computer database system having a DISTINCT specifier. An SQL SELECT statement with a DISTINCT specifier is analyzed to determine if the expression can be optimized, and if so, the SELECT statement is reformulated to improve system performance. In preferred embodiments, the query optimizer eliminates the DISTINCT specifier in the outer select statement to reformulate the query. In other preferred embodiments, a query optimizer reformulates the query before being sent to the database manager to optimize the query to improve system performance.

Abstract: According to an embodiment of the invention, a filer or other storage server is coupled to a network to store files for users of the network. Agents are coupled to the filer, and performs a scan or file walk for a Multi-Appliance Management Application (MMA) which is coupled to the filer and can monitor and manage the filer. A directory structure of the filer may be divided into two or more paths, each of which may be scanned by an independent agent. The results of the scan, or file walk, are saved to a database server. In this way, multiple agents may be used to scan a single storage server, and the amount of time required for the scan is reduced.

Abstract: Content is described having native and export portions. In an implementation, one or more computer-readable media includes instructions that are executable on a computing device to store content in a content container as a native portion and an export portion. The native portion is native to an application that originated the content and the export portion is to provide a published view of the content when the native portion is not supported.

Abstract: Aspects of the invention relate to creating a snapshot of a file system on an OAS system. A snapshot of a file system is an image of a file system at a particular point in time. A snapshot of a file system may be used to restore the file system to its state at the time of creation of the snapshot in, for example, situations where the file system has become corrupted.

Abstract: The present invention provides a federation of clusters for uniform and consistent enterprise-wide data management. The federation is an affiliation of clusters, dispersed over different locations that provide a comprehensive solution to the management of all types of data stored in different devices. Each cluster owns data sources connected to the same network it is attached to. Devices connected to the network, and the cluster for managing data accessible through the network constitute an autonomous area. Results from different locations are consolidated to produce unified results and reports. The enterprise-wide data management allows enterprises to validate compliance with federal regulations and insures that data management objectives are being met in all departments within an organization. In addition to enterprise-wide data management, a member cluster of a federation can perform data management local to its autonomous area and execute policies formulated for that area.
