Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The invention provides a data access method based on a hybrid disk.

[0046] refer to figure 1 As shown, it is a flow chart of the first embodiment of the hybrid disk-based data access method of the present invention.

[0047] In the first embodiment, the hybrid disk-based data access method includes:

[0048] Step S10, starting from the first write cache, counting the number of discontinuous write caches between the first preset number of sectors according to the order of the written addresses.

[0049]The method proposed in this embodiment is suitable for hybrid disks. Generally, mechanical disks are used as data disks, and high-speed random storage media are used as cache disks. The read and write speed is fast and the capacity is large, and some frequently read hot data can be cached to high-speed disks. ...

Abstract

The invention discloses a solid-state hybrid disk-based data access method. The method comprises steps of calculating a number of discontinuous write caches between sectors at an interval of a first preset number according to a write-in address order from a first write cache, reading interval data between the write caches of the sectors at an interval of a first preset number from a data disk when the calculated number is greater than a second preset number, merging the write caches between the sectors at an interval of a first preset number and the interval data to generate a total write caches, and writing data corresponding to the total write cache to the data disk. The invention further provides a solid-state hybrid disk-based data access device. By the use of the solid-state hybrid disk-based data access method and device, a problem that data has to be written into the data disk for multi-time write operation when the write cache addresses are discontinuous can be solved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a hybrid disk-based data access method and device. Background technique [0002] With the maturity of solid-state hard disk technology, a large number of storage products based on hybrid disks of mechanical disks and solid-state hard disks have appeared on the market. Among these products, one of these products uses solid-state hard disks as cache disks, and mechanical disks as When using a data disk, when writing data, it is first written to the solid-state hard disk for cache, and then transferred to the mechanical disk; the hot data is cached in the solid-state hard disk, and if the read data happens to be in the solid-state hard disk, it is directly read from the solid-state hard disk. [0003] As a high-speed storage medium, solid-state drives can greatly improve the performance of storage products when they are used as high-speed and large-capacity caches for mechanica...
