    摘要： Mechanisms identify one or more first storage devices in a first tier of the tiered storage system that may be placed in a minimal power consumption state and identify one or more data segments stored on the one or more first storage devices that are most likely to be accessed during a period of time in which the one or more first storage devices are in the minimal power consumption state. The mechanisms migrate the one or more data segments to one or more second storage devices in one of the first tier or a second tier of the storage system and place the one or more first storage devices in the minimal power consumption state. Access requests to the one or more data segments are serviced by the one or more second storage devices while the one or more first storage devices are in the minimal power consumption state.

    摘要： A mechanism is provided in a storage system for efficient inline data de-duplication. The mechanism receives a write command and a hash key for a portion of data to be written from an application host to a write address. The write command indicates whether the application host is tolerant or intolerant to data loss. Responsive to the write command indicating the application host is tolerant to data loss, the mechanism performs a hash key lookup in a hash index. The mechanism determines whether the portion of data has previously been written to the storage system. Responsive to determining the portion of data has previously been written to the storage system, the mechanism stores a pointer to the previously written data at the write address.

    摘要： A self-contained backup power source such as a battery is provided for components within an electrically powered device such as a storage controller, photocopier or the like, to maintain diagnostic status data and to power a service indicator aid, or diagnostic indicator, such as an LED. A switch selects the backup power source when a primary power source of the electrically powered device is no longer available to the component, such as when the component is removed from the electrically powered device, the primary power source is disconnected as a safety precaution when servicing or replacing the component, or a higher-level assembly, in which the component is provided, is removed from the electrically powered device. The diagnostic indicator may be powered separately from the data storage device.
