摘要： A storage control device includes a processor. The processor is configured to acquire a first size. The processor is configured to calculate, for each of a plurality of storage devices, a total size of first data stored in each of the plurality of storage devices. The first data satisfies a predetermined condition. The processor is configured to select the first data in an ascending order of the total size. A sum of the total size of the selected first data is the first size or less. The processor is configured to copy the selected first data from the plurality of storage devices to a first storage device different from the plurality of storage devices.

摘要： A drive control device, which includes a control module generating an optical driver power supply control signal; a detection module detecting a working state of an optical driver according to the optical driver power supply control signal or receiving an external input signal and generating a switch control signal according to a detection result or the external input signal; and an execution module electrically connected with the detection module and powering on or off power supply on the optical driver according to the switch control signal. The powering-on and powering-off of the optical driver are flexibly controlled, the situation of increase of additional power consumption of a device for a reason that the optical driver is in a standby state for a long time is avoided.

摘要： In an approach to managing racks in a MAID system, a first rack of a data center is identified. The data center comprises a plurality of racks. The first rack corresponds to a request. The request is one of (i) a request to change a power status of a storage device of the first rack or (ii) a request to service the first rack. An optimal placement of the plurality of racks is calculated to satisfy a condition of the request. One or more of the racks are moved from a first location to a second location, based on the calculated optimal placement of the one or more racks.
