Training mechanism-based user habit obtaining method and device in cache management device

Abstract

The invention discloses a training mechanism-based user habit obtaining method in a cache management device. The method comprises the following steps: (S1) obtaining an operation record that a user operates a solid state disk, and obtaining an operating habit of the user according to the operation record; (S2) judging whether the operating habit is a new operating habit or not, if so, replacing an old operating habit with the new operating habit, and if not, further utilizing the old operating habit; (S3) predicting a data page address to be accessed by the user according to the operating habit; and (S4) caching the data page address into the cache management device. Correspondingly, the invention further discloses a training mechanism-based user habit obtaining device in the cache management device. The method and the device are trained in the behavior of repeatedly operating the solid state disk by the user under the new habit, and predict a to-be-executed operation under the new habit, so that the cache management device of the solid hard disk is guided to buffer the to-be-accessed data page address into the cache in advance; and the cache access hit rate is greatly improved.

Description

technical field [0001] The invention relates to a solid state hard disk management method and device, in particular to a method and device for acquiring user habits based on a training mechanism in a cache management device. Background technique [0002] In the cloud computing environment, in order to cope with the challenges brought by massive data and user requests, and to solve the large-scale data access bottleneck faced by traditional databases, distributed caching technology is introduced to provide users with high-performance, high-availability, and scalable data caching services . Enterprises use high-speed memory as the storage medium for data objects, and data is stored in the form of key / value. [0003] Solid State Drive (SSD) is a hard disk made of solid-state electronic storage chip arrays, consisting of a control unit and a storage unit (including FLASH chips and DRAM chips). The specification and definition of the interface, the function and the method of us...

[0006] However, the inherent defect of SSD - write amplification, determines that the FIFO replacement strategy can minimize write amplification. Other replacement strategies such as LRU and LFU will cause serious write amplification and shorten the service life of SSD.
