1. A system for redundant object storage, comprising a plurality of nodes communicatively coupled to one another and configured to:

  • collectively store at least two copies of each of a plurality of objects in order to provide redundancy of each of the plurality of objects in the event of a fault of one of the plurality of nodes;

    monitor access to each object to determine a frequency of access for each object;

    based on the determined frequency of access for each object, redistribute one or more of the copies of the objects such that at least one particular node of the plurality of nodes includes copies of only objects accessed at a frequency below a predetermined frequency threshold; and

    place the at least one particular node in a reduced-power mode.
