Abstract
A method for writing data to a storage pool. The method includes receiving a virtual identifier (ID) and an offset for an object, extracting a node identifier (ID) that identifies a first storage server in the storage pool from the virtual ID, obtaining an object layout (OL) for the object from the first storage server, hashing an object ID and an offset ID to obtain a hashed value, where the virtual ID comprises the object ID and where the offset ID is generated from the offset, identifying a second storage server in the storage pool using a global namespace layout (GL), the OL, and the hashed value, and issuing a write request to write data to the object in the second storage server, where the write request comprises the object ID and the offset.
