> Currently {{SimulatedFSDataset}} (and thus, {{DataNodeCluster}} with
> {{-simulated}}) only supports a single storage per {{DataNode}}. Given that
> the number of storages can have important implications on the performance of
> block report processing, it would be useful for these classes to support a
> multiple storage configuration.
