Patent ID: 8296511

Claim:
A method of managing data on a federated content addressable storage (CAS) system, comprising: determining a group of objects to be stored on a single CAS system of the federated CAS system; obtaining a cookie corresponding a particular one of the CAS systems of the federated CAS system in response to initially writing at least one object of the group of objects, wherein the cookie identifies the particular one of the CAS systems to which the at least one object of the group of objects is written, and wherein the group of objects is associated and determined for storing on the single CAS system prior to the initial writing of the at least one object of the group of objects to the particular one of the CAS systems; and providing the cookie in connection with writing remaining objects of the group of objects following the initial writing of the at least one object of the group of objects to the particular one of the CAS systems, wherein the cookie causes the remaining objects of the group of objects to be written subsequently to the particular one of the CAS systems.
