The System Director maintains all information about the Avid NEXIS file system.

The System Director Appliance can manage more than four Media Packs, up to the limit described in the Avid NEXIS ReadMe, with either the Avid NEXIS | FS Extended license or the Avid NEXIS | FS Advanced license. The System Director Appliance cannot be used with an Avid NEXIS | PRO.

The System Director

• Manages the metadata by storing directory information and file attributes.
• Provides a location to coordinate file access modes (read/write), file locking, range locking, performance data collection, logging, file lookup, and directory change tracking for client systems.
• Provides the following information:
• Identity of all connected storage systems
• Information about the drives, power, cooling and Controllers in the configuration
• Names of workspaces
• Lists of users and groups within the system

The System Director does not store client data (media files); these are stored on the Media Packs (drives) within one or more Engines. System Director metadata is mirrored on the system drives in the Engines or in the System Director Appliance.
