This article describes aspects of the implementation of a project called "Clustered Failover." A Clustered Failover configuration connects two independent file server appliances via a NUMA network to provide file service that can survive hardware faults with minimal disruption to clients. The paper focuses on how the combination of the properties of WAFL (Network Appliance's proprietary log structured file system) and NUMA interconnects minimizes overhead and makes for a relatively straightforward implementation.
