Low-power-consumption mode wakeup recovery method and device for solid state disk and computer equipment

Abstract

The invention relates to a low-power-consumption mode wakeup recovery method and device for a solid state disk, computer equipment and a storage medium. The method comprises the steps: when a commandissued by a host is obtained, enabling the solid state disk to quit a low-power-consumption mode; judging whether the command issued by the host needs data transmission or not, and if not, directly executing the command issued by the host and replying a completion state to the host; if so, awakening other cores to enter a normal working state, and recovering the state and the working parameters before entering the low-power-consumption mode at the same time; detecting the type of the command and the hardware modules needing to be matched, awakening the hardware modules needing to be matched with the command, and configuring hardware working information; transmitting data issued by the host, and replying a command completion state to the host after the data issued by the host is completelytransmitted; and enabling the solid state disk to enter the low-power-consumption mode again. The performance of the solid state disk is improved, the power consumption is reduced, and the effect of improving the stability of the solid state disk is achieved.

Description

technical field [0001] The present invention relates to the technical field of solid-state hard disks, in particular to a recovery method, device, computer equipment and storage medium for a low-power consumption mode of a solid-state hard disk. Background technique [0002] With the rapid development of SSDs (Solid State Drives), performance and power consumption have become important criteria for measuring SSDs, and high performance will inevitably lead to higher power consumption values; therefore, the low power consumption mode of SSDs is particularly important. However, the low-power mode involves power-down of the hardware module, and exiting the low-power mode after receiving the command involves re-powering, data recovery and other actions, which will slow down the command processing speed, increase the wear and tear of the storage particles and the frequent failure of the hardware module. Power on and off and not stable. [0003] At present, the traditional low-pow...

However, the low-power mode involves power-down of the hardware module, and exiting the low-power mode after receiving the command involves re-powering, data recovery and other actions, which will slow down the command processing speed, increase the wear and tear of the storage particles and the frequent failure of the hardware module. Power on and off and not stable

[0003] At present, the traditional low-power mode wake-up recovery mechanism of solid-state drives does not take into account the instability caused by frequent entry into low-power mode, and does not analyze the commands issued by the host to dynamically configure the work of the CPU and hardware peripherals. mode, to a large extent, a lot of useless or redundant actions have been done, which affects the performance and power consumption of solid-state drives, and increases the time to wake up and recover from low-power modes
