| 20080215713 | System and Method for Automatically Enforcing Change Control in Operations Performed by Operational Management Products - A system and method for enforcing change control in operations performed by operational management products (OMPs) are provided. The system and method automate the checking of a request-for-change (RFC) state by an OMP when the OMP is installed in an environment where a change management database (CMDB) has been installed and certain resources or operations have been placed under strict change control. The OMPs of the illustrative embodiments require an RFC identifier to be specified when a change operation of the OMP is invoked. The RFC identifier is used by the OMP to access a service management system so that the OMP may determine if the RFC identifier is valid, IT resources are in the correct state, and the change is scheduled to be performed at the current time. If these checks are passed, then the change operation associated with the RFC is permitted to occur. | 09-04-2008 |
| 20080243860 | Sequential Media Reclamation and Replication - Sequential media reclamation is usually performed after portions of a sequential access volume's data are no longer needed and the unused portion of the volume exceeds a threshold. Improved sequential media reclamation is provided by using a sequential access disk volume (for example, a volume of a virtual tape library (VTL)) embodied as a sparse file. Reclamation of objects stored in the volume is accomplished by nulling out regions of the sparse file that contain the objects that are no longer needed. A replication method is also provided in which information about the objects stored in the sparse file (such as offset and length) is used during replication to enable the correct portions of a target volume (embodied as a sparse file) to be nulled out to match a source volume (also embodied as a sparse file). | 10-02-2008 |
| 20080243942 | ELIMINATION OF REDUNDANT OBJECTS IN STORAGE SYSTEMS - Provided are a method, system, and article of manufacture, wherein a data structure corresponding to a set of client nodes selected from a plurality of client nodes is generated. Objects from the selected set of client nodes are stored in the data structure. A determination is made that an object corresponding to a client node of the selected set of client nodes has to be stored. An additional determination is made as to whether the object has already been stored in the data structure by any client node of the selected set of client nodes. The object is stored in the data structure, in response to determining that the object has not already been stored in the data structure by any client node of the selected set of client nodes. | 10-02-2008 |
| 20080281880 | METHOD FOR STORING DATA FOR RETRIEVAL AND TRANSFER - Provided is a method, system and program for storing data for later retrieval and for transfer within a storage hierarchy. A data storage subsystem stores both individual user files and also managed files, each managed file comprising an aggregation of multiple user files. After receiving user files from a client station, the subsystem stores user files in a retrieval storage pool to facilitate file retrieval. Criteria are subsequently applied to the user files stored in the retrieval storage pool to delete low or lower priority files from the retrieval storage pool. In addition, user files are aggregated in managed files for transfer to another location within the storage hierarchy. | 11-13-2008 |
| 20080281883 | SYSTEM AND PROGRAM FOR STORING DATA FOR RETRIEVAL AND TRANSFER - Provided is a method, system and program for storing data for later retrieval and for transfer within a storage hierarchy. A data storage subsystem stores both individual user files and also managed files, each managed file comprising an aggregation of multiple user files. After receiving user files from a client station, the subsystem stores user files in a retrieval storage pool to facilitate file retrieval. Criteria are subsequently applied to the user files stored in the retrieval storage pool to delete low or lower priority files from the retrieval storage pool. In addition, user files are aggregated in managed files for transfer to another location within the storage hierarchy. | 11-13-2008 |
| 20080294611 | HIERARCHICAL STORAGE MANAGEMENT USING DYNAMIC TABLES OF CONTENTS AND SETS OF TABLES OF CONTENTS - A system, apparatus, and process creates a table of contents (TOC), including one or more table of contents (TOC) entries, to manage data in a hierarchical storage management system. Each TOC entry contains metadata describing the contents and attributes of a data object within an image, which is an aggregation of multiple data objects into a single object for storage management purposes. The TOC is stored in a storage hierarchy, such as magnetic disk, for fast access of and efficient operation on the aggregated TOC entries. The system, apparatus, and process also provide for aggregating the TOC entries from one or more TOCs into a TOC set in the storage management server database. The TOC set may be manipulated and queried in order to find a particular data object or image referenced by a TOC entry. The TOC entries, TOCs, and TOC sets may be dynamically managed by the hierarchical data storage management system through implementation of a set of policy management constructs that define appropriate creation, retention, and movement of the objects within the database and storage hierarchy. | 11-27-2008 |
| 20090119354 | METHOD, SYSTEM, AND PROGRAM IMPLEMENTING RETENTION POLICIES TO ARCHIVE RECORDS - Provided are a method, system, and program for receiving a request to remove a record. A determination is made as to whether a state associated with the record includes at least one hold state and whether the state associated with the record includes at least a retention period that has not expired. The request to remove the record is denied in response to determining that the state associated with the record includes at least one of at least one hold state and one retention period that has not expired. | 05-07-2009 |
| 20090265399 | SPACE RECOVERY WITH STORAGE MANAGEMENT COUPLED WITH A DEDUPLICATING STORAGE SYSTEM - Provided are techniques for space recovery with storage management coupled with a deduplicating storage system. A notification is received that one or more data objects have been logically deleted by deleting metadata about the one or more data objects, wherein the notification provides storage locations within one or more logical storage volumes corresponding to the deleted one or more data objects, wherein each of the one or more data objects are divided into one or more extents. In response to determining that a sparse file represents the one or more logical storage volumes, physical space is deallocated by nulling out space in the sparse file corresponding to each of the one or more extents. | 10-22-2009 |
| 20100223233 | MANAGEMENT OF REDUNDANT OBJECT IN STORAGE SYSTEMS - Provided are a method, system, and article of manufacture wherein one client node is selected from a plurality of client nodes. A determination is made that an object corresponding to a client node has to be stored. A determination is made as to whether the object has already been stored in the server node by the one selected client node. The object is stored at the server node, in response to determining that the object has not already been stored in the server node by the one selected client node. | 09-02-2010 |
| 20100306178 | SEPARATING FILE DATA STREAMS TO ENHANCE PROGRESSIVE INCREMENTAL PROCESSING - Systems, methods, and computer products for separating file data streams for improved progressive incremental processing are provided. The method comprises identifying data in a file, prior to transmission of the data in a data stream to a second system, such that the second system can distinguish first data from second data in the file. The method further comprises processing the first and second data to determine whether the first or second data has changed, and transmitting the first data to the second system in response to determining the first data has changed, so that the first data is stored in a data storage medium in association with third and fourth data previously stored without replacing the third data and fourth data, wherein the third and fourth data comprise older versions of the first and second data, respectively. | 12-02-2010 |
