Enhancements to Disk Space Balancer
Since the initial release of Version 5.2.0, the disk space balancer tool has been improved to distribute containers from highly utilized storage pools on one node in a cluster to less utilized storage pools on other nodes in the same cluster by first classifying storage pools into different bins (based on their utilization level) and then moving containers from storage pools in the highest utilized bin (the source SP) to suitable storage pools in the the lowest utilized bin in two phases. These enhancements are present in Version 5.2.0 as well.
