SCM
System control manager; a microprocessor on a
standard I/O module that monitors and controls other
microprocessors that monitor system state. The SCM
provides a command language for an operator and
allows for remote management of the system. A second
standard I/O module with another SCM provides a
backup control system.
Secondary PCI box
A PCI master box that serves as a backup to the
primary PCI box. See also Primary PCI box.
SIO
Standard I/O module. Module in the master PCI box
that has I/O ports and the system control manager
(SCM) microprocessor.
Soft partition
A partition whose CPU and memory resources can be
allocated from any QBB; defined by using the SRM
console. Also referred to as logical partitions.
Standard I/O
module
See SIO.
System box
The GS160 and 320 enclosure for two quad building
blocks (QBBs).
System cabinet
The GS160 and GS320 cabinet that holds up to two
system boxes, each of which has two QBBs.
System control
manager
See SCM.
System drawer
The GS80 enclosure for one quad building block (QBB).
System
management
console
The PC used to manage the system.
System primary
CPU
The CPU chosen out of all CPUs in all QBBs to be the
primary CPU of the system.
Vaux
Low voltage power present in the system even when 48
volt power is not. Vaux powers the console serial bus,
allowing the system control manager to monitor the
system.
