According to one implementation of the present disclosure, a method for power management is disclosed. The method includes: computing, by a central processing unit, software instructions of a software workload in an active-mode operation corresponding to a first operating point on a performance curve of a performance mode; transitioning from instances of the active-mode operation to instances of standby-mode operation of the CPU, and recording, by a time tracking element, each of a plurality of standby entry data points; transitioning from the instances of the standby-mode operation to the instances of the active-mode operation of the CPU, and recording, by the time tracking element, each of a plurality of standby exit data points; and determining a second operating point on the performance curve of the performance mode based on the recorded standby entry data points and the recorded standby exit data points.

To provide more uniform performance levels for solid state drive (SSDs), the static power level used by an SSD in an idle state is measured and used to determine a static power offset for each of the drives. The static power offset is set as a parameter for the SSD and used to offset a received power supply level for use on the drive. For a data storage system of multiple SSDs, a common scaling factor can be used to set the degree to which the static power offset is implemented, allowing for a choice between uniformity of power and uniformity of performance for the SSDs of a data storage system.

A data processing system may include one or more first memory systems each comprising a first memory device, and suitable for generating analysis information by performing an AI (Artificial Intelligence) computation in order to analyze operation patterns for a plurality of accumulated commands transferred from a host and a plurality of accumulated addresses corresponding to the accumulated commands, and one or more second memory systems each comprising a second memory device having a lower operating speed than the first memory device, and suitable for selectively blocking access to the second memory device in response to the analysis information.

A data storage device including, in one implementation, a non-volatile memory device including a memory block that includes a plurality of memory dies and a controller that is coupled to the non-volatile memory device and that allocates power to non-memory components based on a determined usage of the memory dies. The controller is configured to monitor a utilization of the plurality of memory dies, determine a utilization state of the plurality of memory dies, and calculate an amount of available power allocated to the plurality of memory dies in response to determining that the plurality of memory dies are in a low utilization state. The controller is also configured to determine whether the amount of available power is above a predetermined threshold, and reallocate the available power to one or more components within the data storage device in response to determining that the amount of available power is above the predetermined threshold.

Techniques to control a storage system involve: determining whether available power capable of being supplied by a supplying apparatus of the storage system is less than power required by the storage system; and in response to a determination that the available power is less than the power required by the storage system, adjusting an operation parameter of the storage system based on the available power so as to match the power required by the storage system with the available power. In this way, the performance of the storage system can be at a higher level while the performance of the storage system can remain stable in a case where power of a processor is limited.

A working temperature calculation method for a storage device of a server is provided. Firstly, n detected temperatures are converted into n transformed temperatures according to a composite temperature algorithm. If all of the n transformed temperatures are lower than a strengthen heat dissipation trigger temperature, the lowest temperature of the n transformed temperatures is set as a working temperature of the storage device. If at least one of the n transformed temperatures is higher than the strengthen heat dissipation trigger temperature, the highest temperature of the n transformed temperatures is set as the working temperature. When the storage device receives a temperature read command from the host, the storage device sends an information about the working temperature to the host, and the host controls a heat dissipation mode of the heat dissipation mechanism according to the working temperature.

A CPU of an information processing apparatus (MFP) obtains device information regarding a secondary storage device provided in the MFP, and discriminates, based on the obtained device information, whether the secondary storage device is a type of storage device in which the number of shifts to a power saving state affects the lifetime of the storage device. The CPU determines, as a shift condition for the secondary storage device to shift to the power saving state, a shift time for the secondary storage device to shift to the power saving state, by determining the shift time for the type of storage device in which the number of shifts does not affect the lifetime to be shorter than the shift time for the type of storage device in which the number of shifts affects the lifetime.
