Novel software and hardware collaborative RAID improvement method

Abstract

The invention relates to a novel software and hardware collaborative RAID improvement method, and belongs to the field of hard disk arrays. The RAID software computing module and the monitoring moduleare added to the computer host end, the data path 2 and the counting module are added to the RAID board card end, the current CPU load is monitored through the monitoring module, and when the CPU load is low, the RAID software computing module is used for RAID computing processing, and the computing result is transmitted to the cache module through the data path 2; in addition, whether the data volume in the cache module is larger than or equal to the total data volume (L + 1) or not is calculated through the counting module, if yes, calculation is stopped, and repeated calculation is prevented. Due to the fact that calculation is conducted through the data calculation module and the RAID software calculation module of the RAID board card at the same time, the RAID calculation processingspeed is increased, and remaining CPU resources are utilized. According to the method, the RAID board card is matched with the software, so that faster RAID performance is achieved, and CPU (Central Processing Unit) resource shortage of a computer end cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of hard disk arrays, and in particular relates to a method for improving a novel software and hardware cooperative RAID. Background technique [0002] RAID (Redundant Array of Independent Disks) technology is also known as redundant independent hard disk array technology. Its original intention is to combine multiple relatively cheap small hard disks to replace expensive large-capacity hard disks, and at the same time ensure that no single hard disk is damaged. affect the accuracy of the data. After continuous development, RAID technology has been able to provide a complete storage device solution. While increasing the capacity of the hard disk, it can also fully increase the speed of the hard disk, making data more secure and easier to manage the hard disk. It is precisely because of the high data reliability and high fault tolerance characteristics of RAID technology that RAID technology has a wide range ...
