Method, device and system for responding read-write operation request of host computer by solid state disk

Abstract

The embodiment of the invention provides a method, device and system for responding a read-write operation request of a host computer by a solid state disk (SSD). The method comprises the steps of: judging whether concurrent number of a solid storage unit is not less than a preset value; if so, suspending responding a read-write operating request of the host computer, storing the read-write operation request of the host computer; if not, responding the read-write operation request of the host computer. The scheme provided by the invention suspends the response of the read-write operation request when the concurrent number of the solid storage unit is not less than the preset value, thereby limiting the maximum power consumption of the SSD. Therefore, the reliability of the SSD can be ensured.

Description

Technical field [0001] The present invention relates to the field of storage technology, in particular to a method, equipment and system for a solid state hard disk to respond to a host's read and write operation request. Background technique [0002] Solid State Disk (SSD, Solid State Disk) is a hard disk composed of a control unit and a solid-state storage unit (DRAM or Flash chip). Its interface specifications, functions, usage methods, product appearance and dimensions are the same as ordinary hard disks. Solid-state hard drives do not have the mechanical structure of ordinary hard drives, so they have the advantages of low power consumption, no noise, anti-vibration, low heat, and fast transmission speed. [0003] SSD uses solid-state storage unit chips to form a storage array. The read and write efficiency of a single solid-state storage unit is very low, and the high performance of the entire SSD depends on the concurrent operation of multiple solid-state storage units. Th...

AI Technical Summary

Problems solved by technology

The number of concurrent solid-state storage units is sometimes high and sometimes low, and the instantaneous power consumption of the SSD will also fluctuate greatly. If the instantaneous power consumption is too large, it will cause problems in the reliability of the SSD.

[0007] At present, there is no method to limit the maximum power consumption of SSD in the prior art
