Abstract: A storage system includes a first de-duplication scope comprising a first volume, a first table of hash values corresponding to first chunks of data stored on the first volume, and a first table of logical block addresses of where the chunks of data are stored on the first volume. A second de-duplication scope includes similar information for a second volume. The first scope is used for de-duplicating and storing first data from a first data source and the second scope is used for de-duplicating and storing second data from a second data source. First storage mediums that make up the first volume remain powered off while de-duplication and storage of the second data on the second volume takes place, and second storage mediums that make up the second volume remain powered off while de-duplication and storage of the first data takes place, thereby enabling data de-duplication while saving power.

Abstract: System and method for reducing costs of moving data between two or more of multi-tiered storage devices. Specifically, the system operates by moving only high tier portion of data and merely remapping the low tier data to migration target device, which eliminates a large amount of data movement (low tier) while maintaining the SLA of high tier data. Specifically, when a command to migrate a thin provisioned volume is received from a source primary storage device to another target primary storage device, the system doesn't copy all of the tier1 and tier2 chunk data that the source thin provisioned volume holds, but copies only tier1 chunk data to the target storage device. The copy operation is performed after the storage system prepared the target thin provisioned volume on the target side. After that, tier2 chunks are remapped from the primary storage device to another target primary storage device without copying.

Abstract: Embodiments of the invention include first storage mediums having first storage characteristics for making up a first pool of capacity of a first tier of storage, and second storage mediums having second storage characteristics for making up a second pool of capacity of a second tier of storage. Free capacity of the first and second pools is shared between the first and second tiers of storage. When the first pool has an amount of free capacity available over a reserved amount of free capacity reserved for first tier data, a first quantity of second tier data is moved from the second tier to the first tier. In exemplary embodiments of the invention, the first and second storage mediums are contained within one or more thin provisioning storage systems, and data is moved between the first and second tiers by allocating thin provisioning chunks to the data being moved.

Abstract: Physical storage space in a storage system is not allocated to a segment of a targeted volume until the segment of the volume is first targeted for storing write data. When write data is received, the storage system determines whether the targeted volume is designated for storing a first data type that is accessed frequently by I/O operations or designated for storing a second data type that is accessed less frequently than the first data type. Physical storage space for storing the write data is allocated from a first logical partition of the physical storage designated for storing the first data type when the targeted volume is of the first data type and from a second logical partition of the physical storage designated for storing the second data type when the targeted volume is of the second data type. Allocation of frequently accessed data is controlled and performance bottlenecking avoided.

Abstract: A thin provisioning storage system is able to present a thin provisioned volume to a computer, such that the computer stores data to the volume as if storage space on disk drives was already allocated for the volume. Upon receiving a write request from the computer, in which the write request is directed to an area of the volume for which storage space on the disk drives has not yet been allocated, the storage system allocates new space on the disk drives. When allocating the new space, the storage system obtains a designated performance level for the volume, and determines a number of storage extents to be allocated to the volume based upon the determined performance level. The storage system also is able to take into account performance metrics for the disk drives and/or array groups when selecting locations from which to allocate the storage extents.

Abstract: Systems and methods for dissolving the bottleneck issue of management task requested from management client to the storage virtualizer which consolidates externally attached storage arrays while providing a single management point of the entire system to the management client. Specifically, by utilizing the storage virtualizer to distribute received management tasks to respective external attached arrays, it can off load tasks, thus reducing the workload on the storage virtualizer itself. Because of the task distribution, the storage virtualizer consequently does not need to copy and hold detailed information of each storage volume in the respective attached storage arrays, thereby avoiding any inconsistent information between the arrays and the virtualizer when the configuration change has been done on the external array.
