A Dell PowerScale cluster is a highly distributed network-attached storage (NAS) architecture that uses the power and efficiency of automation through parallelism wherever possible. Examples include multiple nodes participating in data reconstruction in the event of a hard drive failure, multiple workers and data streams accelerating replication and backup tasks, and so on. Such cluster tasks require a distributed scheduling, processing, and reporting framework to help manage them efficiently. This processing and scheduling framework is referred to as the OneFS Job Engine.
