Method and system for improving IO performance on basis of K1 system

Abstract

The invention discloses a method and system for improving IO performance on the basis of a K1 system. The method comprises the following steps: establishing a preset number of disk array groups on a hard disk; establishing logical units with the same capacity and stripe size in the disk array groups and mapping the logical units to a host; respectively establishing corresponding physical volumes according to the recognized logical units mapped to the host, and integrating the physical volume into a volume group; and establishing a preset number of striped logical volumes according to the disk array groups and the logical units. According to the method and system disclosed in the invention, multiple stripes are used so that data can be dispersed into different physical volumes by an operation system through the logical volumes, after that, the data is dispersed into different disk array groups through a stored disk array group manner, and finally, the data IO is distributed onto different physical hard disks through stripes of the disk array groups, so that the IO performance is enhanced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for improving IO performance based on a K1 system. Background technique [0002] Inspur Tiansuo K1 system is the result of the major special project of my country's 863 program "development and application of high-end fault-tolerant computers". my country's first key application host Inspur Tiansuo K1 system was officially launched, marking that my country has become the third country in the world to master the new generation of host technology after the United States and Japan, and is expected to change my country's long-term dependence on imports of large hosts in core fields such as finance and telecommunications. embarrassing situation.

Problems solved by technology

[0003] Since the K1 minicomputer is mainly used in the core data platform of the customer, the I / O performance of the system plays a vital role. However, when multiple processes access a disk at the same time, disk conflicts may occur

Most disk systems have limits on the number of accesses (I / O operations per second, IOPS) and data transfer rates (the amount of data transferred per second, TPS)
