| 20080294859 | PERFORMING BACKUP OPERATIONS FOR A VOLUME GROUP OF VOLUMES - Provided are a method, system, and article of manufacture for performing backup operations for a volume group of volumes. Information on a volume group associating a plurality of volumes and backup settings is maintained. A volume group is selected to which the backup settings apply. A volume group associates hosts and volumes, indicating the hosts that are enabled to access the volumes in the volume group. Automatic backup operations for the selected volume group are invoked to generate backup information for the volume group indicating backups performed with respect to the volumes associated with the volume group, process the backup information for the volume group to determine whether to perform a backup with respect to the volume group according to the backup settings, and backup each volume in the volume group in response to determining to perform the backup operation for the volume group. | 11-27-2008 |
| 20090204759 | ON-LINE VOLUME COALESCE OPERATION TO ENABLE ON-LINE STORAGE SUBSYSTEM VOLUME CONSOLIDATION - A mechanism to permit consolidation of storage subsystem volumes into larger, more easily managed volumes and an operating system device driver which includes a trap mechanism for intercepting calls from a host into logical unit devices that were previously consolidated into a single physical volume. A map converts such calls to a logical unit device into a corresponding offset in the single physical volume. A driver accesses the single physical volume with corresponding offsets to transfer data associated with a particular logical unit device. So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime. | 08-13-2009 |
| 20090265567 | METHOD, APPARATUS AND SYSTEM FOR REDUCING POWER CONSUMPTION INVOLVING DATA STORAGE DEVICES - The invention provides a method, apparatus and system for reducing power consumption involving data storage devices. One embodiment involves a process for storing data in a first memory, and in response to the first memory exceeding a first threshold, migrating the data from the first memory to a second memory. In response to the second memory exceeding a second threshold, the process then involves migrating the data from the second memory to the third memory, wherein the second memory is sized and configured to store data targeted for the third memory to intelligently maintain a portion of the third memory in an inactive state. | 10-22-2009 |
| 20090300397 | METHOD, APPARATUS AND SYSTEM FOR REDUCING POWER CONSUMPTION INVOLVING DATA STORAGE DEVICES - The invention provides a method, apparatus and system for reducing power consumption involving data storage devices. One embodiment involves storing data in a first memory; in response to the first memory exceeding a first threshold, migrating the data from the first memory to a second memory; in response to the second memory exceeding a second threshold, then activating a third memory if the third memory is in active; and in response to the second memory exceeding a third threshold greater than the second threshold, migrating the data from the second memory to a third memory; wherein the second memory is sized and configured to store data targeted for the third memory to intelligently maintain a portion of the third memory in an inactive state. | 12-03-2009 |
| 20100082933 | AUTOMATED METHOD TO CONFIGURE A DATA STORAGE SYSTEM - An automated, computer-implemented method to configure a data storage system comprising a host computer, a storage controller in communication with said host computer, and a plurality of data storage media in communication with said storage controller, wherein the method provides a configuration algorithm encoded as computer readable program code, and executes that computer readable program code. The configuration algorithm creates a command procedure comprising a plurality of physical configuration commands to establish a physical configuration for the data storage system. The configuration algorithm further creates a command procedure comprising a plurality of logical configuration commands to establish a logical configuration for the data storage system. | 04-01-2010 |
