Abstract
Abstract A method and system for improving load balancing in a file server is disclosed. The method includes determining the existence of an overload condition on a storage device, the storage device having a plurality of retrieval streams accessing at least one file thereon; selecting a first retrieval stream reading a file; replicating a portion of said file being read by said first retrieval stream onto a second storage device; and reading the replicated portion of said file on said second storage device with a retrieval stream capable of accessing the replicated portion of said file. The method and system enables the dynamic replication of data objects to respond to fluctuating user demand. The method and system is particularly useful in file servers such as multimedia servers delivering continuously in real time large multimedia files such as movies.
