Data processing device for multi-disk server and corresponding processing method

Abstract

The invention discloses a data processing device of a multi-disk server and a corresponding processing method. When a user sends a write request, the method inquires whether the multi-disk server has corresponding write data, and if not, outputs a corresponding index that can store information, and write the write request to the public queue. When each write thread judges that its corresponding disk is normal, it will compete to obtain the write request from the public write queue, and write the corresponding write data to the corresponding disk. , and complete the index information stored in the corresponding empty location; the method locates the disk where the data to be read is located when the user sends a read request, and writes the read request into the read queue of the disk, and the read queue of the disk When the thread detects that its corresponding read queue is not empty, it obtains the corresponding read request from the read queue and reads data from the corresponding disk. The apparatus corresponds to the method. The invention makes the data distribution on each disk more uniform and improves the maintenance efficiency.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data processing device of a multi-disk server and a corresponding processing method. Background technique [0002] For servers with multiple disks, when carrying IO-type services, if the data scale is large, regardless of the type of disk, such as SATA / SAS / SSD, frequent reading and writing of data will easily lead to a high failure rate. At the same time, quite a few services are designed and deployed in the mode of single-disk-single-service-process. Therefore, when a disk fails, the service process on the disk fails or exits, which will inevitably have a negative impact on the business. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a data processing device and corresponding processing method for a multi-disk server, so that the data on each disk is distributed more evenly and the maintenance efficiency ...

Problems solved by technology

[0002] For servers with multiple disks, when carrying IO-type services, if the data scale is large, no matter what type of disk, such as SATA / SAS / SSD, etc., frequent reading and writing of data will easily lead to a high failure rate

At the same time, a considerable number of businesses are often designed and deployed in the mode of single disk and single business process. Therefore, when the disk is damaged, the business process on the disk fails or exits, which will inevitably have a negative impact on the business.
