Metadata Controller


The EFS metadata controller is the captain system, designed to control all movement and connections to any large-scale deployment of multiple EFS nodes. The metadata controller provides high availability to an EFS Workgroup and operates as the traffic management system, controlling and distributing data across the EFS Parallel files system on all nodes, confirming that no single point of failure occurs.

A second metadata controller can be added to the primary to provide total redundancy, ensuring that facilities in mission critical environments need never skip a beat.
