Chapter 1. Reference Information

This chapter provides an overview of the Eserver pSeries 670, including a logical description and a

physical overview of the system. Additional details pertaining to the server are also provided. They include

the following:

v Memory overview and ordering rules

v General description of the operator panel

v Cabling rules

v System location rules and descriptions

v Powering on and powering off the system

v Power flow

The pSeries 670 server is a multiprocessor, multibus system composed of the following subsystems:

v 7040 Model 61R, a 24-inch wide and 42-EIA-high rack unit that also contains the following:

– An 8-EIA unit power subsystem, consisting of two redundant bulk power assemblies that distribute

bulk power at 350 V to each of the subsystems.

– An optional 2 EIA-unit integrated battery feature (IBF), which is available in either a redundant or

non-redundant configuration.

v 7040 Model 671 Processor Subsystem, a 17 EIA-unit processor subsystem, which contains the

processors, L3 cache, memory, and service processor and a 1 EIA-unit media subsystem containing a

diskette drive, a CD-ROM, and an operator panel, with space for up to three additional optional media

There is an option to expand the number of RIO (in this case RIO-2) ports to eight. This allows up to

two RIO-2 I/O subsystems, each with 2 GB-per-second transfers on each planar. Processor speeds up

to 1.5 GHz are also available. Additional memory cards that operate at the higher 567 MHz bus speed

are available.

v 7040 Model 61D I/O Subsystem, 4 EIA-units, which can have up to 20 PCI adapters and up to 16

DASD disk drives.

This subsystem may also be purchased to allow 10 or 20 PCI-X adapters, for use with the RIO-2

cabling option. Additionally, there is an option that allows 1 GB RIO-2 on each remote I/O port. RIO-2

allows up to 2 GB I/O transfers when cabled as a single planar loop (four CEC RIO-2 ports per I/O

v A Hardware Management Console (HMC), which provides a standard user interface for configuring and

operating partitioned systems. One HMC can support multiple partitions on multiple systems.
