Abstract
An apparatus comprises a processing device configured to initiate load balancing for a storage cluster comprising two or more storage nodes, to predict performance metrics for the storage nodes at two or more time points in a designated future period of time, and to select, based at least in part on the predicted performance metrics, a first one of the storage nodes as a source storage node and a second one of the storage nodes as a target storage node. The processing device is further configured to determine at least one storage object residing on the source storage node which, when migrated to the target storage node, reduces a performance imbalance rate of the storage cluster for at least the designated future period of time, and to perform load balancing for the storage cluster by migrating the at least one storage object from the source to the target storage node.
