摘要: A cluster-wide published configuration system and method is provided for assigning host nodes to virtual interfaces (VIFs) in a cluster of data storage systems. A coordinating VIF manager publishes a set of failover rules using a replication database. The coordinating VIF manager monitors VIF hosting status within a cluster. In the event of a VIF failure, the coordinating VIF manager publishes a reassignment of host nodes using a single read-write transaction of a replication database service. Secondary VIF managers in the cluster must perform VIF hosting in accordance to the reassignment. If a secondary VIF manager can not activate an assigned VIF it must publishing new reassignment of VIF hosts via the replication database service.
