Abstract: Briefly, the disclosure describes embodiments of methods or apparatuses for document processing at distributed processing nodes.

Abstract: A transaction safe file system uses two sets of file allocation tables and bitmap images to perform file modifications on one of the sets while the other set remains a last known good set. After a modification is complete, a pointer is changed to the newly modified set, and the newly modified set becomes the last known good set. The sets are then synchronized. The file allocation table is used to define cluster chains while the bitmap image is used to determine if a cluster is free or not. In some operations, only the bitmap image may need to be manipulated. The file system may be used in a transaction safe mode as well as a non-transaction safe mode.

Abstract: Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units.

Abstract: An archive cluster application runs across a redundant array of independent nodes. Each node runs an archive cluster application instance comprising a set of software processes: a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests for data, the storage manager manages data read/write functions, and the metadata manager facilitates metadata transactions and recovery. The policy manager implements policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. It associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. The archive manages itself independently of client applications, acting automatically to ensure that object policies are valid.

The apparatus reallocates the real storage area to the duplicate logical volume divided area to update the management information. The apparatus identifies, based on the management information, the real storage area allocated to the duplication source logical volume divided area corresponding to the duplicate logical volume divided area. The apparatus copies data stored in the real storage area to the real storage area.

Abstract: A communication device management program that enables efficient use of memory space in receiving data using remote direct memory access (RDMA) techniques. The receiving node transmits a virtual ID corresponding to a receiving process to a remote sending node. A sending process in the sending node specifies this virtual ID when starting data transmission. If the receiving node has not reserved a memory area corresponding to that virtual ID, the sending node transmits a reservation request to the receiving node, which causes a data receiving memory area to be reserved for use by a communication device in the receiving node. In the sending node, the sending communication device begins sending transmission data in RDMA mode, from a memory area managed by the sending process to the reserved data receiving memory area. The receiving communication device directs incoming transmission data to a memory area managed by the receiving process.

Thereafter, the super files representing groups of similar files are presented to the client, where each of the super files includes at least one of the queried terms. Other methods and apparatuses are also described.

Abstract: A method (and corresponding system and computer program product) detects modified files and/or directories in a storage device. The method builds a file-sector coordination table for files in the storage device before relinquishing access control of the storage device to a host computer. The method passively monitors write transactions in the storage device from the host computer. The method identifies sectors affected by the monitored write transactions and stores in a sector list. The method regains access control of the storage device from the host computer and builds a list of modified files by intersecting the sector list with the file-sector coordination table. The method may optionally share the list of modified files with related applications.

When the processing content of the information processor is to retrieve a free area from the area management information, a physical management block size determined from the physical characteristics of the information recording medium is used. When the processing content is to acquire a link destination from the area management information, minimum access unit of the information recording medium is used. Consequently, overhead can be lessened when the area management information is accessed.

Abstract: A storage requirements estimating system estimates the storage required for a proposed multidimensional clustering data by modeling wasted space. The amount of wasted space is modeled by calculating the cardinality of the unique value of the clustering key for the proposed configuration. Cardinality may be determined by estimation techniques. Specific values for wasted space and total space may be determined in response to the determined cardinality. Comparison of estimates for different proposed clustering configurations facilitate a selection among proposed multidimensional clustering data configurations.

Abstract: A bank maintains a financial document in a first storage system when a record date is later than a pre-selected date and in a second storage system when the record date is earlier than or equal to the pre-selected date. The bank receives and inputs a request for the financial document from a client and compares the record date to the pre-selected date to determine if the record date is later than, earlier than, or equal to the pre-selected date. In processing the request, the bank can utilize a computer terminal, connected to the storage systems through a processing unit, to access one of the storage systems in response to the comparison of the record date to the pre-selected date. After accessing the appropriate storage system, the bank retrieves the requested financial document and can then reproduce and distribute the requested financial document.
