Methods and apparatus associated with storing data in high or low energy zones are described. Example apparatus include a data storage system (DSS) that protects a message using an erasure code (EC). A location in the DSS may have an energy efficiency rating or a latency. Example apparatus include logics that produce an EC that has a likelihood of use, that select a location to store the EC in the DSS based on the energy efficiency rating, the latency, or the likelihood of use, that store the EC in the location, and that compute an order of retrieval for an EC stored in the location. The order of retrieval may be based on the energy efficiency rating or the latency. The EC may also have a priority based on the number of erasures for which the EC corrects. |

1. An apparatus for storing data, comprising:
a data storage system (DSS) that protects a message using an erasure code (EC), where a location in the DSS has an energy efficiency rating; a processor; a memory that stores electronic data that manages ECs for messages in the DSS; a set of logics; and an interface that connects the processor, the memory, the DSS, and the set of logics, the set of logics including:
an EC logic that produces an EC for a message present in the DSS, where the EC has a likelihood of use;a storage logic that stores the EC in a location in the DSS, where the storage logic selects the location based, at least in part, on the energy efficiency rating of the location in the DSS or the likelihood of use of the EC; anda retrieval logic that computes an order of retrieval, based, at least in part, on the energy efficiency rating of the location in the DSS or the likelihood of use of the EC, and where the retrieval logic retrieves the EC from the DSS based, at least in part, on the order of retrieval. |
