A pSeries 690 system can have up to two racks, which support up to eight I/O drawer
subsystems.
The Hardware Management Console for pSeries (HMC) is used to manage the
resources in the system. The system can be configured as a full system partition, which
means that all resources of the system are used as a single system.
The system can also be configured into multiple (or logical) partitioned systems. With a
logically partitioned system, system resources can be divided into a number of systems
each running in its own partition.
Numerous configurations of pSeries 690 systems can be managed from one Hardware
Management Console. A second Hardware Management Console can be used for
redundancy.
System Configurations
The system configuration may vary. Possible configurations include:
v Multiple pSeries 690s attached to one Hardware Management Console (HMC)
v Two HMCs attached to one pSeries 690
v Two HMCs jointly managing up to eight pSeries 690s
The following components make up the base configuration of the pSeries 690:
v Rack and Bulk Power Subsystem (BPA) The BPA is the main power control unit for
the pSeries 690. This redundant bulk power assembly distributes power at 350 V to
each drawer where conversion is made to the required chip level.
v Processor Subsystem The processor subsystem is a 17 EIA-unit-high drawer. The
processor subsystem contains the backplane, up to four processor modules, up to 16
L3 cache modules, up to four I/O books, up to eight memory books, and cooling
blowers. The processor subsystem drawer also contains the power subsystem
components used in the conversion of 350 V bulk power to the supply voltages
required by the various internal components.
Several memory book sizes are available. The minimum memory requirement to
operate this system is 8 GB, and the maximum amount of memory is 256 GB.
v Media Drawer The media drawer is a 1 EIA-unit high drawer containing an operator
panel, 1.44 MB floppy diskette drive, one SCSI optical drive (either a CD-ROM or a
DVD-RAM), signal cables, power cables, a 1 EIA-unit-high 24-inch rack-mountable
sheet metal enclosure, and miscellaneous mechanical hardware. Three additional
SCSI bays are available to add optional CD-ROMs, DVD-RAMs, or 4-mm tape
drives:
– Variable Speed SCSI-2 CD-ROM Drive
– SCSI DVD-RAM Drive
– 4-mm Internal Tape Drive
v Integrated Battery Feature (IBF) (optional) The IBF is a 2 EIA-unit-high drawer that
can be added to your system. The IBF provides backup electric power in case of a
power outage. You can install up to two IBFs in the base rack configuration. One
additional IBF can be installed in an expansion rack.
