CPS6650 must always be ordered to provide
base mainframe.
Includes all components shown
in box with dotted outline. This is base
mainframe for entire DPS range of performance
levels — DPS-l,2,3,4,5.
DPSZ,3
levels are
obtained by addition of cumulative
performance enhancements as shown. DPS-4,5
can be obtained only if DPS—3
is configured.
DPS—l,2,3,4,5 designations do not imply
relative performance levels,
i.e., DPS-2 is
not twice as fast as DPS-l.
All mainframe
components are freestanding, except that base
processors are
packaged
in one cabinet,
and
memory to the maximum of 1024KW/4fl96KB per
SCU is contained
in the SCU cabinet.
Each
processor, SCU,
IOM has own power supply.
At least one motor/generator set is required
but is not included
in base main price. See
Section VII.
For each IOM there are components which must
be configured and considerations which apply
within the IOM.
See Section IV.
Every system must have at least one URP
subsystem.
There is the choice of using a
unit record processor URPfl692 within an IOM
cabinet, sharing IOM power supply, or using a
freestanding URP0609 which has own power
supply.
Use of URPG602 affects physical I/O
channel capacity of IOM.
A minimum tandem mainframe consists of two
processors,
two
SCUs,
and
two
IOMs.
The base
mainframe
(CPS665Z)
always gives you two
processors.
Additional SCU and IOM must be
separately configured.
