18 IBM eServer zSeries 900 Technical Guide
2.1 Design highlights
The z900 design is a result of the continuous evolution of the S/390 CMOS since the early
9672 servers were introduced, in 1994. This robust design has been continuously improved,
adding even more capacity, performance, functionality, and connectivity. The z900 servers are
the first servers that implement the z/Architecture.
The main objectives of the z900 system design, which are covered in this chapter and in the
following ones, are:
To offer a
flexible infrastructure to concurrently accommodate a wide range of operating
systems and applications, from the traditional S/390 and zSeries systems to the new world
of Linux and e-business.
To have state-of-the-art
integration
