| Zusammenfassung: | An apparatus in one embodiment comprises a storage system having at least first and second storage tiers each comprising a plurality of storage devices. The storage system implements a parallel file system comprising at least first and second sets of storage servers. The first set of storage servers is configured to access directories of the parallel file system that are stored in storage devices of the first storage tier, and the second set of storage servers is configured to access directories of the parallel file system that are stored in storage devices of the second storage tier. The storage system is further configured to move data between the first and second storage tiers by moving data files between different directories of the respective first and second storage tiers. One or more servers of the first set may be generated as respective new server instances on one or more compute nodes. |
