AI Technical Summary

Technical Problem

Conventional storage systems fail to equalize drive utilization rates, leading to performance limitations due to concentrated access on specific drives, which results in overall system performance deterioration.

Method used

A storage system with multiple storage nodes that includes a storage control unit, where drives are divided into physical chunks, and data relocation is performed to equalize drive utilization rates based on monitored drive utilization rates.

Benefits of technology

The system improves storage performance by efficiently operating multiple backend drives by equalizing drive utilization rates, thereby eliminating concentrated access and enhancing overall system performance.

Abstract

This invention provides a storage system and data placement method that can improve the performance of a storage system by efficiently operating multiple backend drives. [Solution] The storage system is constructed by having multiple storage nodes, each of which includes a storage control unit and is allocated multiple drives. The storage control unit reads and writes data to physical chunks in response to I / O requests from the host device. A drive has multiple physical chunks that are divided to store data. The storage control unit monitors the drive utilization rate for each of the multiple drives and, based on the drive utilization rates of the multiple drives, performs data relocation, moving data located in the physical chunks of the source drive to the physical chunks of the destination drive in order to equalize the drive utilization rates of the multiple drives.
