IBM 3090 Processor Complex Support Units

The IBM 3090 Processor Complex is the most powerful IBM computing system available. The IBM 3090 Processor Unit performs the data processing functions of the system. It is supported by a number of required or optional units, which are described in this publication.

The quantity required of each support unit depends on the model of the IBM 3090 Processor Unit. Outline configuration details are provided in the IBM 3090 Processor Unit publication GS11-0133.

Required Unit Types:

Optional Units:

IBM 3089 Model 3 Power Unit

The 3089 contains a motor generator and it, or an equivalent device, provides 400 Hz power to the IBM 3097 Power and Coolant Distribution Unit from which it is distributed to the different frames of the IBM 3090 Processor Unit.

Highlights include:

IBM 3097 Power and Coolant Distribution Unit

The IBM 3097 Power and Coolant Distribution Unit provides the combined functions of power distribution to the 3090 Processor Complex and water cooling to the IBM 3090 Processor Unit. The Model 1 differs from the Model 2 by providing Input/Output Power Sequence and Control (TOPS) capability. The more compact and less expensive Model 2 can be field upgraded to the Model 1 in five hours, plus the time required to connect IOPS cables.

IBM 3092 Processor Controller

The IBM 3092 Processor Controller Models 1, 2 and 3 monitor and control the status of all physical units within a 3090 Processor Complex.

The Models 1 and 2 contain duplicate processor and are supported by duplicate 3370 Direct Access Storage Devices often permitting the Processor Controller to continue operation after component failures.

All models of 3092 perform similar function These are:

System Initialisation and Control:

Monitoring and Error Logging:

Error Recovery, Fault Diagnosic and Service Support:

IBM 3180 Model 140 Display Station

The IBM 3180 Model 140 Display Station 1s a monochrome unit used to perform multiple console roles in a 3090 Processor Complex.

Optional Units

A number of optional units may be attached to the 3090 Processor Complex. These include:

IBM 3179 and IBM 3180 Displays

According to user needs, IBM 3179 colour and IBM 3180 Model 1 monochrome displays, or other supported devices, may be channel-attached via an IBM 3274 Control Unit for use as MVS or VM operator consoles.

IBM 3287 and 4224 Printers

Up to two optional console printers can be attached to the IBM 3092 Processor Controller.

Four models are supported for copying console display images:

Console Table

The IBM console table provides an optional operator workstation for one or two operators and their display consoles.
