Abstract
A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into a plurality of systems each having multiple nodes. The systems have one or more replication links each being formed to indicate replication of data from one system to another system in a replicated environment where each system is configured as a sub-domain in a Domain Name System (DNS) infrastructure. A DNS alias synchronization method comprises maintaining updated information, within each system, of all replication links involving that system and of DNS aliases of other systems associated with all replication links involving that system (S602-S607). This enables that system to process network-based requests, on behalf of the other systems, without redirecting the requests from the other systems to that system.
