In a StorageGRID system, what is the role of an admin node?

The role of an admin node in a StorageGRID system is to handle administrative functions. This includes tasks such as managing user access and permissions, configuring system settings, and overseeing system operations. The admin node acts as the central management point for the StorageGRID system, allowing administrators to perform important system configurations and maintenance through a user interface or API.

Admin nodes ensure that the overall system is functioning correctly and provide tools for monitoring and reporting on system performance or issues. While handling administrative functions, the admin node plays a crucial role in maintaining the integrity, security, and efficiency of the storage system.

Each of the other roles mentioned, like managing data operations, storing user credentials, and coordinating log storage, are actually performed by other nodes or components within the StorageGRID architecture, reinforcing why the administrative functionality is distinct to the admin node.
