Abstract
A performance metric of a data shard stored in a first storage portion is monitored. It is determined that the performance metric of the data shard exceeds a threshold. In response to the determination that the performance metric exceeds the threshold, the data shard is reassigned to a second storage portion selected based on an over-provisioning bias of the second storage portion that is different than an over-provisioning bias of the first storage portion or the over-provisioning bias of the first storage portion is increased.
