摘要： Data for deduplication is received. The received data is deduplicated if selected conditions corresponding to the deduplication are satisfied, wherein the selected conditions include a deduplication ratio, a data deduplication threshold, and a data quiescence measure. Deduplication of the received data is discontinued if the selected conditions corresponding to the deduplication are not satisfied.

摘要： A mirrored storage system for applications is provided, which enables and supports the variation and dynamic adaptation of the Recovery Point Objectives (RPO) based on policies. Furthermore, methods are provided for running such a mirrored storage system. Said mirrored storage system comprises a first storage system and at least one further storage system, wherein said first and said further storage system are connected via at least one mirror link. An application accesses said mirrored storage system via a network. Therewith, the data to be stored as response to a write command of said application can be mirrored according to a configurable time-varying RPO requirement of the application transmitting the corresponding write command.

摘要： Various embodiments for optimized power savings in a storage virtualization system are provided. First meta data for physical resources which describes a power status of a storage resource in one of a powered-on/read-write, powered-on/read only, and powered-off power state is created. Second meta data for each of the physical storage resources which determines an actual performance of the physical storage resources and which supports optimization of a powering-on and a powering-off of the physical storage resources is created. A write request from one of a host and application to logical and virtual storage resource is executed.

摘要： Various embodiments for an Input/Output (I/O) path selection based on workload types are provided. A port workload controller is adapted to control the workload types of ports for accessing a storage device. A storage access command is received by the port workload controller from an application being executed on a virtual server on a physical server. The workload types related to the storage access command are determined. Storage access paths between the application and the storage device having the same workload types as the determined workload types related to the storage access command are determined. Storage access paths mapping data that is controlled by the port workload controller is used. A selected storage access path is selected out of the determined storage access paths having the least utilization. The storage device is accessed via the selected one of the plurality of storage access paths.

摘要： A method to select a deduplication protocol for a data storage library comprising a plurality of data storage devices configured as a RAID array, by establishing a normal deduplication protocol, a RAID failure deduplication protocol, and a multiple storage device failure deduplication protocol. The method receives host data comprising a plurality of interleaved data blocks. If the system is operating without any storage device failures, then the method processes the host data using the normal deduplication protocol. If the system is operating with a storage device failure, then the method processes the host data using the RAID failure deduplication protocol. If the system is operating with multiple storage device failures, then the method processes the host data using the multiple storage device failure deduplication protocol.

摘要： A method to access a data in a RAID array comprising a plurality of data storage media, wherein information is written to said plurality of data storage media using a RAID configuration, wherein the method receives from a requester a command comprising a data access priority indicator. If a RAID rebuild is in progress, the method determines if the data access priority indicator is set. If the data access priority indicator is set, the method executes a command selected from the group consisting of writing information to the target logical block array range, and returning to the requestor information read from the target logical block array range.
