  • Patent number: 9501473
    Abstract: A method involves: detecting a storage resource indication within a workflow request and, in response to the storage resource indication, generating an availability indication. The storage resource indication indicates a storage resource (e.g., by directly or indirectly identifying or selecting the storage resource). The availability indication indicates that the indicated storage resource is not available for subsequent workflow requests. The availability indication is generated prior to allowing the consumer that generated the workflow request to use the storage resource. The workflow request can include a request to allocate a logical storage structure (e.g., a volume or logical disk). The logical storage structure is allocated in response to the workflow request. If the workflow request is denied or expires, the logical storage structure is deleted.

  • Patent number: 7636830
    Abstract: A method, system, computer system, and computer program product to allocate storage resources among multiple logical volumes. In response to a request to perform a set of operations on multiple logical volumes, a set of allocations of available storage space for performing the set of operations is made. At the time of identifying the storage regions to use for each allocation, the remaining operations and the storage regions that would be available for performing the remaining operations are examined. The rules for implementing each of the logical volumes can be evaluated as part of this examination. If it is apparent that one of the remaining operations will fail based upon a particular set of allocations, space allocated for a previous operation can be de-allocated and alternative allocations can be examined to find a set of allocations that enable the request to be performed successfully.

  • Patent number: 7516286
    Abstract: A method, system, computer system, and computer-readable medium that enable a copy of data to be converted from a full-data snapshot to a space-saving snapshot, or vice versa, while retaining all the contents of the snapshot. Full-data snapshots can be used for efficient read operations and off-host processing operations. Space-saving snapshots can be used to store multiple copies of primary data in a minimum amount of storage space without consuming unnecessary storage space to store duplicate copies of data that are not changing. The ability to convert between full-data and space-saving snapshots enables organizational storage, backup, and recovery needs to be met using the best type of snapshot for a given operation.

  • Patent number: 7509468
    Abstract: A method, system, computer system, and computer-readable medium to trigger protection of a set of data based upon the type or class of the data in the set and/or an amount of data that has changed since some prior point in time. Types of protection that can be triggered include full backup, incremental backup, switching to a different type of continuous replication, intermittent replication, and virus detection. Using the type of the data as a basis for triggering protection enables the operational significance of different sets of data to be taken into account when allocating protection resources. Data sets may be pre-classified, or an automated determination of the type of a data set may be determined by variables measured at run-time. The amount of the changed data in a set that triggers protection may vary in accordance with the type of the set of data.

  • Patent number: 7487308
    Abstract: A method, system, and computer program product for identifying and reserving suitable replacement storage devices for use when a storage device underlying a logical volume fails or when the size of the volume is to be increased. Replacement devices are reserved if they conform to the intent of a creator of the logical volume and at the time of creation or reconfiguration of the logical volume. Volume management operations like resizing the volume and evacuating data from the volume use the reserved disks that have already been allocated as suitable to preserve the intent of the creator of the logical volume. Reserving replacement disks in advance ensures that a backup disk is available and eliminates the need to perform a lengthy, time-consuming search for a suitable replacement disk that conforms to the intent of the logical volume.

  • Patent number: 7467257
    Abstract: A method, system, computer system, and computer program product to specify the particular characteristics of hardware to acquire to enable a logical volume to be maintained in accordance with the purpose for which the logical volume was created. In response to a command to perform an operation on a logical volume, existing storage that can be used to perform the operation is identified. If the existing storage is insufficient to perform the operation, a specification is developed for the additional storage to acquire to enable the operation to be performed successfully. Connectivity of the additional storage is also specified to storage objects in the existing logical volume so that the newly-acquired resources can be used for their intended purpose when acquired.

  • Patent number: 7383410
    Abstract: A method, system, and language to express storage requirements. The language provides keywords and rules corresponding to commands for configuring a set of storage devices to provide requested capabilities of a logical volume. The language also has keywords and constructs for defining capabilities. The language supports direct inheritance of a capability, where a template specifies another template that contains rules to be used to provide a given capability. The language also supports indirect inheritance of a capability, where a template requires a capability but does not provide an implementation of the capability. In addition, the language is processed to “merge” rules by selecting a single storage device that conforms to more than one rule when possible. Merging rules enables a minimum number of storage devices to be used to meet a given logical volume configuration and set of capabilities.

  • Patent number: 7162575
    Abstract: A method, system, and computer program product for adaptively implementing capabilities of a logical volume. If a particular capability is an inherent attribute of an existing storage device, the existing storage device is chosen to implement the volume. If the particular capability is not an inherent attribute of an existing storage device, one or more storage devices are selected and configured to provide the capability. If a capacity is requested for the logical volume and a storage device provides only a portion of the capacity, multiple storage devices having the capability are combined to provide the requested capability and capacity.

  • Patent number: 7143259
    Abstract: A method, system, and computer program product for preserving the intent of a logical volume creator with the logical volume. The creator of a logical volume defines certain characteristics of that logical volume. In response to the user's requirements, the system explores the possibilities for providing the characteristics in the existing storage environment. The system then implements the logical volume and stores the intent, along with a corresponding set of rules for configuring the logical volume, with the logical volume. As a result, volume management operations like resizing the volume and evacuating data from the volume use the rules to preserve the intent of the creator. By ensuring that the logical volume consistently conforms to rules fulfilling the original intent, a consistent level of availability of the logical volume can be achieved to fulfill contractual availability requirements for storage service level agreements.
