Abstract:
An example method for balancing disk usages in a virtualized computing environment may include generating, by a storage manager configured to manage the virtualized computing environment, predicted-disk-utilizations for a plurality of physical disks provisioned to a virtual disk in the virtualized computing environment. In response to a determination that a first predicted-disk-utilization for a first physical disk selected from the plurality of physical disks exceeds a predetermined-utilization-threshold, the storage manager may generate a storage-balancing policy for splitting the virtual disk into a number of disk slices and distributing the number of disk slices to a subset of candidate physical disks selected from the plurality of physical disks, wherein the storage-balancing policy provides a minimum data-movement-variance for distributing of the number of disk slices to the subset of the candidate physical disks.
