Methods, apparatuses, and systems related to a memory device are described. A controller may be configured to predict a temperature of a memory based on a real-time temperature of the controller. Based on the predicted temperature of the memory, the controller may execute a remedial action to reduce an actual temperature of the memory for executing an upcoming operation.

A method for regulating a chip temperature, belong to the technical field of integrated chips, and applied to multi-core processor chips. The method comprises: pre-setting a threshold set consisting of multiple thresholds gradated by magnitude; and further comprises: step S1, detecting, in real time, a real-time temperature produced by a processor chip; step S2, judging whether the real-time temperature has exceeded one or more thresholds in the threshold set; and step S3, using a pre-set strategy to shut down a pre-set rule number of cores corresponding to the number of thresholds exceeded by the real-time temperature. The method for regulating a chip temperature can deal with the scenario where a chip temperature is higher than a threshold due to continuous load increase, and has high reliability.

The present disclosure generally relates to improved lifetime of a data storage device utilizing an energy assist element. Rather than applying the same current to each energy assist element of a device, each energy assist element has a write current specific to the energy assist element. The unique applied current results in the corresponding energy assist elements having substantially the same temperature during operation. Obtaining substantially the same temperature during operation provides predictable and repeatable device performance and increases the lifetime of the entire data storage device as all energy assist elements should have substantially the same lifetime.

A media library includes a library housing, a heat-producing device, one or more storage media and an air mover assembly. The library housing can include a library interior where the library interior can include a first wall and a second wall positioned opposite the first wall. The heat-producing device can be positioned near the first wall of the library interior. The one or more storage media can be positioned in the library interior between the heat-producing device and the second wall. The air mover assembly can be is configured to move air into the library interior through the first wall and out of the library interior through the second wall. The heat-producing device can include one or more of a media drive, a power supply and a controller. The air mover assembly can move air through the heat-producing device before the air moves through the one or more storage media.

A system for providing continuous cooling to a storage rack, including a storage rack, including a first storage node and a second storage node; a first cooling loop including a first cooling distribution unit (CDU); a second cooling loop including a second cooling distribution unit (CDU); a first inlet switching valve coupled between the first storage node and each of the first and the second CDUs; a second inlet switching valve coupled between the second storage node and each of the first and the second CDUs; wherein, when the first cooling loop experiences a failure, a state of the first inlet switch and a state of the second inlet switch is adjusted to i) prevent the first CDU from providing cooling of the first storage node and the second storage node, ii) allow only the second CDU to provide cooling of the first storage node and the second storage node.

A data storage library system includes a data storage library, at least one environmental conditioning unit, at least one data storage drive retained within the data storage library, and at least one access door for providing access to an interior portion of the data storage library. The system also includes a library controller, wherein the library controller is configured to initiate a service mode prior to and during a service procedure performed within the data storage library, and further wherein at least one operational state within the at least one data storage drive is changed during the service mode. The change in the at least one operational state may be, for example, an increase in temperature within the at least one data storage drive, or the insertion of a data storage cartridge into the at least one data storage drive during the service mode.

An electronic device comprising at least one memory and at least one processor which function as, a temperature acquisition unit configured to acquire a temperature of a recording medium attached to the electronic device, a setting unit configured to set at least one of settings including a first setting and a second setting, and a control unit configured to perform control, in a case where the first setting is set, and when a predetermined condition regarding a rise in the temperature of the recording medium is satisfied, to restrict at least a particular operation requiring a writing speed to the recording medium at a predetermined speed or higher, and in a case where the second setting is set, not to restrict the particular operation even when the predetermined condition is satisfied.

A media library includes a library housing, a heat-producing device, one or more storage media and an air mover assembly. The library housing can include a library interior where the library interior can include a first wall and a second wall positioned opposite the first wall.
