Operation processing method of data storage system and data storage system

Abstract

An embodiment of the invention provides an operation processing method of a data storage system and the data storage system. The operation processing method includes that a storage magnetic disk of the data storage system comprises a hash table bucket and index blocks and receives data operation processing request message which carries data identification, the corresponding index block is obtained from a harsh table according to the data identification, mapping relation of the data identification and the index block is stored in the hash table, and each index block stores an index record which includes the mapping relation of the data identification and a data block storing data identified by the data identification. Identification of the data block storing the data identified by the data identification is obtained from the index record of each index block, and corresponding data operation processing is conducted on the data block that the identification of the data block corresponds to. By means of the method, the harsh table bucket and the index blocks can be stored in the storage magnetic disk to enable the operation method of the system to be further simplified. Visit performance of the magnetic disk can be further improved to some extent.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to an operation processing method of a data storage system and a data storage system. Background technique [0002] The web cache (Web Cache) needs to cache hot data, the web server (Web Server) needs to store massive data, and a large number of web pages and video files also need high-performance storage. One of the key indicators for user experience in web access is fast data storage, indexing, and reading. [0003] In the current prior art, the third extended file system (Third extended file system, Ext3) is a general and common file system in the Linux system, and it can be used to store massive keyword (Key) data. Among them, the storage structure of the Ext3 directory is similar to a tree, and the indexing technology of the Ext3 directory is to determine which page node of the Htree the file is placed on based on the hash value of each directory entry name. The ...

Problems solved by technology

[0004] However, if the file directory is very deep or there are many files in the directory (for example, more than 1000), when accessing the file, it needs to go through multiple levels of directory reading and matching comparison in the final directory, and the access performance will be poor

Therefore, when accessing disks through directory organization in the prior art, there is a defect of poor access performance
