Abstract

Various embodiments of the present invention are directed toward extending a federation of servers and balancing the data load of said federation of servers, in order to improve accessibility and scope of the system by moving the first backup data structure on the second server to the new server, creating a second data structure on the new server, and creating a second backup data structure for the second data structure on the second server. To balance the load, certain embodiments employ a method comprising suspending writes to the selected logical partitions, copying selected logical partitions to the new physical partition, redirecting reads and writes to the logical partitions in the new physical partition, and removing the original selected logical partitions. Alternative embodiments for balancing data load comprise the substitute steps of creating a temporary replication stream for the selected logical partitions to the new physical partition, copying selected logical partitions to the new physical partition, deconflicting inconsistencies in the logical partitions on the new physical partition, redirecting reads and writes for the selected logical partitions to the logical partitions in the new physical partition, and removing the original selected logical partitions that were copied to the new physical partition.
