Locating a file object in a storage system includes determining at least one characteristic of the file object, obtaining a subset of nodes in the storage system by applying the at least one characteristic to criteria for storing file objects at particular ones of the nodes in the storage system, and examining the subset of nodes to determine if any contain the file object. A metadata location server may be used to obtain the subset of nodes. The criteria may include at least one policy relating to placement of objects corresponding to files at the time the files are created. The policies may relate to owners of the files. The characteristic information may include the owner of a target file corresponding to the file object, the date that the target file was created, a business organization associated with the target file, and/or the size of the target file.

The capacity of a data storage management system may be increased with disclosed methods and systems. One method may increase the capacity of a data storage management system that polls a plurality of monitored elements in a data storage environment. The method includes creating a flag for a poll request and associating a first value for the flag with a first subset of the plurality of monitored elements. The method further includes interpreting a first poll request that includes the first value for the flag as directed to the first subset and interpreting a second poll request that does not include the first value for the flag as not directed to the first subset.
