The configuration object can include storage node information for a first set of storage nodes available to a server. The configuration object determines, from the storage node information, a second set of storage nodes for inclusion in a map. The configuration object maps each storage node in the second set of storage nodes to a different index value in a set of index values. The configuration object receives an object identifier for a first object, transforms the object identifier into a resulting index value in the set of index values and, based on a determination that a first storage node is mapped to the resulting index value in the map, selects the first storage node as a target storage node for servicing a request to perform a first operation with respect to the first object. ## Claims ### Claim 1 A computer program product comprising a non-transitory computer readable medium storing therein a set of computer executable instructions, the set of computer executable instructions comprising instructions for: creating a configuration object having an associated type to which the configuration object applies and file store information for a first set of file stores available to a server;
