Chapter 2 System Features 2-7
Note – The SC is the system controller that controls CPUs and memory and handles
communication with the XB.
2.1.5 System Control
System control of the M8000/M9000 servers refer to the system control contained
within the XSCFU that runs the XSCF and every component controlled by the XSCF.
As long as input power is being supplied to the server, the XSCF constantly monitors
the server even if all domains are powered off.
The following functions are provided to increase system availability:
■ Configuration management and monitoring
■ Cooling unit (FAN unit) monitoring
■ Domain status monitoring
■ Power-on and power-off of peripheral devices
■ Complete control and monitoring of the server through abnormality monitoring
■ Remote partitioning for domain configuration and management
■ Server management and monitoring functions by the user through an external
network connection
■ Notifying the system administrator of fault information on the server
■ Remote console input-output
2.2 Partitioning
A single M8000/M9000 server cabinet can be divided into multiple independent
systems for operation. This dividing function is called partitioning.
This section describes features of partitioning and system configurations that can be
implemented through partitioning.
2.2.1 Features
The individual systems resulting from partitioning can be built in the M8000/M9000
servers. These individual, divided systems are called domains. Domains are
sometimes called partitions.
