Abstract

Described is a Multi-purpose System Package which is modularly incremental and covers the needs for the processor/memory system unit, the I/O tower for a higher performance Processor/Memory System Unit, a Direct Access Storage Device (DASD)/Tape rich expansion unit tower, and a I/O Adapter rich extension unit tower. Included within the package is the capability to power, cool, and interconnect additional expansion functions which may be modularly added to the base package unit. DASD and Tape when properly configured may be concurrently maintained within the towers. All elements which make up the configurations will be automatically detected and the configuration will be saved in storage.

Multipurpose System Package

      Described is a Multi-purpose System Package which is modularly
incremental and covers the needs for the processor/memory system
unit, the I/O tower for a higher performance Processor/Memory System
Unit, a Direct Access Storage Device (DASD)/Tape rich expansion unit
tower, and a I/O Adapter rich extension unit tower.  Included within
the package is the capability to power, cool, and interconnect
additional expansion functions which may be modularly added to the
base package unit.  DASD and Tape when properly configured may be
concurrently maintained within the towers.  All elements which make
up the configurations will be automatically detected and the
configuration will be saved in storage.  Any change to the
configuration between separate power-on cycles will be detected,
verified back to the user, and the change noted in storage.  In all,
cases the management of the elements will be with the view of the
composite system providing a single system image perspective.

      Figs. 1 and 2 show the tower unit frame 1 mounted on four
casters for mobility.  The tower unit constitutes the basis for the
Multi-Purpose System Package.  The tower unit has been designed to
contain radiation up to 5 Ghz, cool processors with cycle timers to
7.5 ns, and provide redundant power up to 800 watts of load at the
bulk level.  There are six different configurations of the tower
unit.  These configurations are differentiated by the backplane, by
the power system, and by the functions contained within the tower
unit.  Fig. 1 is the front view of the tower unit, and shows the
power compartments 3, save/restore compartment 5, operator panel
compartment 4, and front book cage 21.  Also shown in Fig. 1 is the
front air plenum and the I/O expansion cooling/electromagnetic
compatibility (EMC) cover and cabling run.

      There is a front and rear power compartment, as well as a front
and rear book cage.  The components which populate the front and rear
power compartments as well as the book cages varies by system unit
and by expansion/extension unit usage of the tower function.  The
rear power compartment contains a single section which may contain
either a single fully functional power supply, or an AC/base bulk
power supply 20 segment of a distributed power system.  Both the full
function 400-watt power supply and the AC/base 400-watt bulk power
supply contain their own cooling by means of two fans and dock to the
backplane.   The front power compartment is divided into four
sections, a top and bottom shelf and both shelves consisting of a
right segment and a left segment.  The right segment of either shelf
may contain feature bulk power units 11, which dock directly to the
AC/base bulk power supply 20 when it is present; otherwise, these
compartments remain empty.  Dependent upon the configuration, the
feature bulk power supply units are optional.  The left compartment
on both shelves accepts Battery...
