Server Management Connectivity 2.6.1 Chassis Management Module The main controller in the chassis management module is an Intel® XScale IXP425 microcontroller or an Intel® EP80579 Integrated Processor that runs Linux to provide a robust operating environment. The service processor provides IPMI communication within the system in addition to the user interface used to manage the system over Ethernet. See Section 3.5 for a description of this board. 2.6.2 Compute Module Management Each compute module contains an Integrated Baseboard Management Controller (BMC) that is responsible for all management local to the module, including power control, reset, sensor reading, remote KVM, remote media and remote serial console. The Integrated BMC also gathers events to be stored in the server event log. However, the compute module's Integrated BMC is managed by the chassis management module and must communicate with the chassis management before providing any of these management features. This architecture allows the chassis management module to control the security of all components in the system. 12 Revision 1.7 Intel order number E15155-010
