Problems solved by technology

[0004] However, the service life of the current SSD memory card is relatively short. In order to avoid errors in the data written to the SSD memory card, the SSD memory card needs to be replaced frequently, which increases the cost of the cache
At the same time, the Cache software must often manage and update the hot data in the SSD memory card, so that the operation of the Cache software wastes system resources such as CPU resources of the server

Abstract

The embodiment of the present invention discloses a data buffer device, a data storage system and a method. The data buffer device is connected to a data processing apparatus through a data interface. The data buffer device includes: a controller, and a memory connected with the controller. The memory is used for caching the hotspot data in a hard disk connected to the data buffer device, and the controller is used to read and write data into the memory according to the requestsof the data processing apparatus. By using the present invention, not only the data read and write performance can be enhanced, and also the waste of system resources can be prevented.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a data cache device, a data storage system and a method. Background technique [0002] The CPU (Central Processing Unit, Central Processing Unit) of data processing equipment such as servers and other equipment is constantly developing, from the original single-core development to the current multi-core multi-thread technology, but the development of hard disk storage devices is slow due to technical reasons. The performance of reading and writing data to the mechanical hard disk cannot keep up with the CPU performance. When the CPU reads or writes data to the hard disk, it takes time to wait, resulting in low data service processing efficiency, and the data reading and writing performance cannot keep up with the CPU performance. Raise and raise. [0003] The high-speed cache Cache technology currently used can solve the above problems to a certain extent. In the ex...
