system controller The system controller consists of the System Controller board and the system controller software. The system controller software manages platform and domain resources, monitors and controls the platform and domains, configures domains and the platform, provides access to domain consoles, provides the date and time to the Solaris operating environment, provides the reference clock signal used throughout the system, provides console security, performs domain initialization, provides a mechanism for updating the firmware on the boards installed in the system, and provides an external management interface using SNMP.
