Problems solved by technology

[0008] Since the capacity of modern hard disks increases over time, responding to receipt of an "end of life" message from a data storage drive is a challenge to the data storage system by replicating the entire collection of data stored on the data storage drive to a single healthy data storage drive. has become very time-consuming and resource-intensive for storage processors

Abstract

A technology for relocating the data stored in an end-of-life source storage driver is characterized in that an individual destination driver section corresponding to a driver section positioned in asource storage driver is identified by selecting the individual storage drivers within the set of the healthy storage drivers in the storage driver group in a cyclic manner and identifying the individual destination driver sections from each selected storage driver; the corresponding destination driver section replaces the driver section positioned in the source storage driver and is used to storethe data copied from the driver section positioned in the source storage driver, and the data is copied in parallel from a set of the plurality of driver segments positioned in the source storage driver to the storage driver where the corresponding destination driver segment is positioned, and the set of the plurality of driver segments is selected based on a current total input / output load determined for each of the set of the healthy storage drivers.

Description

technical field [0001] The present disclosure relates generally to intelligent data storage systems that provide RAID (Redundant Array of Independent Disks) technology, and more particularly to methods for relocating data from end-of-life storage based on storage drive load in data storage systems that use mapped RAID technology. drive data. Background technique [0002] A data storage system is an arrangement of hardware and software that typically includes multiple storage processors coupled to non-volatile data storage devices such as magnetic disk drives, electronic flash drives, and / or optical drives. The storage processor service hosts the I / O operations received from the host. The received I / O operations specify one or more storage objects (such as logical disks or "LUNs") to be written, read, created, or deleted. The storage processor runs software that manages incoming I / O operations and performs various data processing tasks to organize and protect host data rece...
