Task allocation method, system, electronic device and storage medium of solid state hard disk

Abstract

The application discloses a task allocation method, system, electronic equipment, and storage medium of a solid-state hard disk. The task allocation method includes: dividing the data management module into multiple data management groups; determining the business scenario according to the working status of all master data management modules ; When the business scenario is a high-bandwidth scenario, control the master data management module and the slave data management module to work in the corresponding CPU cores, and assign tasks to all master data management modules and all slave data management modules; when the business scenario is high In the quality of service scenario, control the master data management module to work in the corresponding CPU core, and assign tasks to all master data management modules. The application can set task allocation methods according to business scenarios, and realize high-quality-of-service or high-bandwidth data processing under the condition of limited hardware resources. A solid-state hard disk task distribution system, an electronic device, and a storage medium disclosed in the present application also have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a task allocation method, system, electronic device and storage medium of a solid-state hard disk. Background technique [0002] Solid State Drive (SSD) is usually divided into different modules according to different functions, such as the data management module DM (Data Manager) responsible for data management, the write management module WM (write manager) responsible for writing nand operations, The recycling block management module RBM (Reclaim Block Manager) responsible for garbage collection and the log management module JM (Journal Manager) responsible for snapshot preservation. The quality of service (QOS) of the system is affected by the delay of read and write operations. The quality of service of the system is mainly affected by the delay of read and write operations, and the bandwidth BW (Band Width) of the system is mainly affected by the conc...

Problems solved by technology

However, when the CPU hardware is limited, the number of CPU cores allocated to the data management module is limited. When high bandwidth is required, the concurrency within the data management module is limited by the processing power of the CPU, and concurrent reading will be affected.
