Device and corresponding method for processing data of multi-disk servers

Abstract

The invention discloses a device and a corresponding method for processing data of multi-disk servers. The method includes querying the multi-disk servers to determine whether corresponding write data are available in the multi-disk servers or not when write requests are issued by users, outputting an empty position if the corresponding write data are not available in each multi-disk server, writing the wrist requests into public queues, competitively acquiring the write requests from the public write queues when each write thread judges that disks corresponding to the write thread are normal, writing the corresponding write data into the corresponding disks, and completely supplementing index information stored in the corresponding empty positions; positioning the disks where corresponding read data are located when read requests are issued by the users, writing the read requests into read queues of the disks, acquiring the corresponding read requests from the read queues if read threads of the disks detect that the read queues corresponding to the read threads are not empty, and reading the data from the corresponding disks. The corresponding index information can be stored in the empty positions. The device corresponds to the method. The device and the corresponding method have the advantages that the data on the various disks can be uniformly distributed by the aid of the device and the method, and accordingly the maintenance efficiency can be improved.

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.
