Abstract: In one embodiment, a method for managing data includes collecting workload information for a data storage device in a data storage system over a period of time. A peak workload of the data storage device for the period of time is determined. A maximum workload threshold for the data storage device in the data storage system over the period of time is also determined. Movement of additional workload to the device in the data storage system is prevented during a subsequent period of time when the data storage device is predicted to be at about the peak workload for the data storage device in response to a determination that adding the additional workload would cause the workload of the device to exceed the maximum workload threshold.

Abstract: In one embodiment, a system includes a processor and logic integrated with and/or executable by the processor, the logic being configured to cause the processor to: collect, by the processor, workload information for a computing/storage device for a present time period and one or more previous time periods; determine, by the processor, a maximum workload parameter for the present time period and the one or more previous time periods; determine, by the processor, a maximum workload threshold that corresponds to the maximum workload parameter; compute, by the processor, a difference between the maximum workload threshold and the maximum workload parameter; and determine, by the processor, an amount of workload to move to the computing/storage device based on the difference. Other methods and computer program products are presented in additional embodiments.

Abstract: Provided are a computer program product, system, and method for modeling workload information for a primary storage and a secondary storage. A determination is made of: a first type and second type of Input/Output (I/O) operations with respect to extents configured in the primary storage; a cumulative I/O workload for the primary storage based on a first type and a second type of I/O operations at different cumulative storage amounts of the primary storage indicating a concentration of the I/O workload on the primary storage; and cumulative I/O workload for the secondary storage based on the first type and the second type of I/O operations at different storage amounts indicating a concentration of the I/O workload of the first type of I/O operations on the secondary storage. A performance gap is determined based on the cumulative I/O workloads for the primary and secondary storages at one of the storage amounts.

Abstract: A power adaptor is connected between a power supply and an electronic device. The electronic device includes a device charging connector, and an electricity storing unit connected to the device charging connector. The power adaptor includes a power source connector and a first magnetic body. The power source connector is capable of electrically connecting with the device charging connector such that the electricity storing unit is charged by the power supply. The first magnetic body is arranged on the power source connector. The electronic device further includes a second magnetic body. When the electricity storing unit is fully charged, a direction of magnetic field of the second magnetic body is set such that a repelling force is generated between the first magnetic body and the second magnetic body, thus an electrical connection between the power source connector and the device charging connector is disconnected.
