Claim One:
1. A system, comprising: a first storage system; a second storage system in communication with the first storage system; wherein the first storage system and the second storage system are key/value based object storage devices, wherein respective objects kept in the first and second storage system has their own attached meta-data; and wherein the first storage system and the second storage system store and serve objects; wherein the system includes a tiered storage system where the first storage system is a higher priority storage system than the second storage system; wherein the tiered storage system includes a probabilistic algorithm engine to predict access patterns based on a window of objects and to consider object usage variants to identify those of the objects of the tiered storage system that are to be kept within the first storage system, wherein the probabilistic algorithm engine computes a discriminant fair-value, wherein the probabilistic algorithm engine calculates respective fair values of objects to identify based on a comparison with the discriminate fair value those of the objects of the tiered storage system that are to be kept within the first storage system, the fair values calculated as one of more than two values within a numeric range, one end of the range indicating a propensity for storage in the first storage system, the other end of the range indicating a propensity for not being stored in the first storage system.
