Automatic discovery
Single power button press, physical location-based discovery and
configuration capability. Although this feature is mostly hardware-dependent,
xCAT 2 was developed to ease integration for new hardware. The plug-in
software architecture provides an easy development mechanism for the new
hardware.
Plug-in architecture for compartmental development
Add your own xCAT functionally to do whatever you want. New plug-ins
extend the xCAT vocabulary that is available to xCAT clients.
Notification infrastructure
By using this feature, you can watch for xCAT DB table changes via the
notification infrastructure.
SNMP monitoring
Default monitoring uses SNMP trap handlers to handle all SNMP traps.
