pSeries 670 Overview
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
devices.
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
subsystem).
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.
