Storage device for a high voltage electrical power including at least two modules connected in series, each module including at least one dc power-source in a container with positive and negative terminals. The system and method include a data source specification to indicate the data to be retrieved from the data sources so that the report may be generated based upon the extracted data. Additionally, the mechanism maintains a list optimize control identifying whether one of the plurality of access requests is currently optimizing a waiters list of access requests waiting to access to the data object. Data flow can be reconfigured to minimize register accesses for different operations.
