1. A data storage system for connection to a primary power source, the data storage system comprising:
- one or more data storage media;
one or more interfaces, each interface able to connect to at least one of the data storage media so as to couple power from the primary power source to the at least one of the data storage media;
one or more energy modules, each energy module being able to connect to an interface for providing back-up power to the one or more of the data storage media in the event of a failure of the primary power source wherein, the data storage system has a plurality of power domains each having one or more data storage media, each power domain being powered by the one or more energy modules in the event of a failure of the primary power source.
