Client and a server and methods thereof for data management relating to shared data storage

摘要

A distributed shared data storage such as the distributed shared memory exemplified with the DSM Master can seamlessly migrate (i.e. move) in the runtime between different nodes without affecting the user perceived performance according to embodiments of the present invention. This is achieved by using more than one replica simultaneously operating towards different master databases during the migration. That is, all distributed shared memory replicas can automatically and seamlessly be migrated to another master database, thus making the communication more flexible and efficient.
