Abstract

The embodiment of the invention relates to a method and a device for realizing load balancing, wherein the method for realizing load balancing comprises the following steps: receiving a data access request which comprises an address and length of to-be-accessed data; determining an access area in a logic unit corresponding to storage equipment according to the address and the length of the to-be-accessed data; if the access area is a hotspot area, distributing a fast path for the data access request. The embodiment of the invention is the fast path with better IO request distribution performance of the access hotspot area, and therefore, the IO request processing speed of the access hotspot area can be increased, and the IO request processing property is improved, thereby improving the system service quality.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular to a method and device for realizing load balancing. Background technique [0002] In order to improve the reliability of data transmission and avoid a single point of failure, multiple paths are often used to connect the application server and the storage system. The multi-path software is responsible for managing multiple paths, and switches the input-output (Input Output; IO for short) request, also called data access request, to the backup path when the preferred path fails, so as to ensure uninterrupted business. In addition to improving system reliability, another important function of multipath software is to achieve load balancing, that is, to distribute multiple IO requests to multiple paths to improve the overall data throughput performance of the system. Allocate multiple IO requests from the application server to multiple paths for tra...
