The Swarm API made it possible to develop a callback file system to provide a traditional file system interface. This made integration with our document imaging system almost completely transparent. Through this custom callback file system, we were also able to implement additional features such as file encryption and file caching to further improve security and performance.” Additionally, Mr. Brown mentioned Swarm’s ability to gracefully manage disk failure without service disruption as a benefit. “We haven’t had any node failures, but we’ve had a disk failure. When this occurred, Swarm responded by automatically creating additional replicas on other drives. We were able to replace the failed drive and then Swarm rebalanced the replicas across all drives.”
