Chapter 1. RS/6000 Introduction
Throughout 1997 IBM greatly simplified its RS/6000 product line by
eliminating redundant offerings and introducing new models that cover a
broad range of price and performance. In 1998, IBM continued this mission
by enhancing its server line with better performance and by offering bundled
solutions that target high availability markets and customers requiring
outstanding graphics performance.
The RS/6000 family is a scalable, compatible line of RISC UNIX workstations,
servers, and supercomputers that are reshaping the way companies operate.
This economical family of systems fulfills the computing requirements of
many small businesses, workgroups, and large enterprises. Powered by
IBM’s award winning AIX operating system, the RS/6000 has the advanced
technology and architecture needed to grow and adapt to your customer’s
ever changing workloads.
This publication covers the IBM RS/6000 43P 7043 Models 150 and 260
entry-level and technical workstations. The RS/6000 Models 150 and 260 are
workstations that are intended to enhance the RS/6000 family’s competitive
product line for the price-conscious UNIX market. The RS/6000 Models 150
and 260 are the systems targeted toward those customers looking for a
reliable, highly expandable system.
