A set of interconnected storage systems supporting different types of storage devices and different performance attributes are intelligently applied to process types, such as journal entries. The processes are ranked according to a predetermined priority ranking. Storage devices in the storage system having similar performance attributes are pooled and ranked according to their performance attributes. The highest priority process is matched with available logical devices from available storage pools that rank highest in the processes performance priority. A cache is similarly allocated from the highest ranking access speed logical devices. |
