    摘要: A method for managing extents in a data storage system includes monitoring usage statistics for an extent residing on one or more powered-up storage devices. In the event the extent has not been accessed for specified period of time (as determined from the usage statistics), the method automatically compresses the extent and migrates the extent to an intermediate repository. Once the amount of data in the intermediate repository reaches a specified level, the method migrates the extent from the intermediate repository to one or more normally powered-down storage devices. If I/O is received for the extent while it resides in the normally powered-down storage devices or the intermediate repository, the method automatically migrates the extent from the normally powered-down storage devices or the intermediate repository to the normally powered-up storage devices. A corresponding apparatus and computer program product are also disclosed.

    摘要: A method for more effectively distributing the I/O workload in a data replication system is disclosed herein. In selected embodiments, such a method may include generating an I/O request and identifying a storage resource group associated with the I/O request. In the event the I/O request is associated with a first storage resource group, the I/O request may be directed to a first storage device and a copy of the I/O request may be mirrored from the first storage device to a second storage device. Alternatively, in the event the I/O request is associated with a second storage resource group, the I/O request may be directed to a second storage device and a copy of the I/O request may be mirrored from the second storage device to the first storage device. A corresponding system, apparatus, and computer program product are also disclosed and claimed herein.

    摘要: A system and method implementable in a JAVA® application for providing C++ language friend-style access that grants JAVA® objects access to methods of another JAVA® object. The method comprises steps of: providing a method in the implementing JAVA object for determining the name of a JAVA object class that has called a method within the implementing JAVA object; comparing the JAVA object class name against a list of object names that have been granted access rights to the method in the implementing JAVA object; and, in response to the comparing, one of: enabling execution of the method of the implementing JAVA object upon determination that the calling object class is a member of the list, or, preventing execution of the method upon determination that the calling object is not a member of the list.

    摘要: In one embodiment, a method for determining pricing for data storage includes receiving from a data provider a request indicating an amount of data storage space in at least one of one or more tiers of data storage, receiving data from the data provider to store in the at least one of the one or more tiers of data storage, storing the data provider's data in the at least one of the one or more tiers of data storage, and calculating a base price for storage of the data provider's data. In another embodiment, a tiered storage system includes a processor, a memory, logic adapted for determining an amount of a data provider's data in each of at least two tiers of data storage, and logic adapted for calculating a price for storage of the data provider's data.

    摘要: A priority-based method for replicating data is disclosed herein. In one embodiment, such a method includes providing a primary storage device and a secondary storage device. Multiple storage areas (e.g., volumes, groups of volumes, etc.) are designated for replication from the primary storage device to the secondary storage device. A priority level is assigned to each of the storage areas. Using these priority levels, the method replicates the storage areas from the primary storage device to the secondary storage device in accordance with their assigned priority levels. Higher priority storage areas are replicated prior to lower priority storage areas. A corresponding computer program product and system are also disclosed herein.
