摘要
Load balancing of activities on physical disk storage devices is accomplished by monitoring reading and writing operations to logical volumes on the physical disk storage devices. A list of exchangeable pairs of logical volumes is developed based on size and function. Statistics accumulated over an interval are then used to obtain access activity values for each logical volume and each physical disk drive. A statistical analysis selects one logical volume pair. After testing to determine any adverse effect of making that change, the exchange is made to more evenly distribute the loading on individual physical disk storage devices.
