SIO Standard I/O module. Module in a PCI box that has I/O
ports, the system control manager (SCM) microprocessor,
and SRM console firmware.
SMC System management console; a PC, software, and termi-
nal server used to manage the system.
Soft partition A collection of resources within a hard partition. Re-
sources can be allocated among soft partitions. In con-
trast to hard partitions, a QBB can provide resources to
more than one soft partition. Soft partitions are defined
by using the SRM console. Also referred to as logical
partitions.
SRM console Firmware on the standard I/O module that provides a
command-line interface for operator control of the sys-
tem or of a partition. The SRM console is responsible for
booting the operating system and passing system con-
figuration data, discovered during power-up, to it.
