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.
A PCI master box that serves as a backup to the
primary PCI box. See also Primary PCI box.
Standard I/O module. Module in the master PCI box
that has I/O ports and the system control manager
(SCM) microprocessor.
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.
See SIO.
The GS160 and 320 enclosure for two quad building
blocks (QBBs).
The GS160 and GS320 cabinet that holds up to two
system boxes, each of which has two QBBs.
See SCM.
The GS80 enclosure for one quad building block (QBB).
The PC used to manage the system.
The CPU chosen out of all CPUs in all QBBs to be the
primary CPU of the system.
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.
