    摘要: A method implemented in a computer infrastructure including a combination of hardware and software includes receiving from a local computing device a request to securely delete a file. The method also includes determining the file is deduplicated. The method further includes determining one of: the file is referred to by at least one other file, and the file is not referred to by another file. The method additionally includes securely deleting links associating the file with the local computing device without deleting the file when the file is referred to by at least one other file. The method also includes securely deleting the file when the file is not referred to by another file.

    摘要: Systems and methods for reducing power consumption and power leakage in hybrid storage clusters is provided. More specifically, the systems and methods for reducing power consumption select a particular cache (memory) technology in hybrid storage clusters based on performance requirements and/or other parameters associated with an application (file or process). The method can be implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The program instructions are operable to monitor access patterns of one or more applications in one or more memory technologies in a computing system. The program instructions are also operable to select a memory technology to store the one or more applications based on the access patterns of one or more applications.
