With well over 750,000 systems shipped worldwide, the success of the iSeries is
realized with the highest customer satisfaction index in the industry, as measured
by IBM internal studies. The foundation of success starts with the design of the
system, the architecture. Those components are described in this chapter.
In brief, success factors for the iSeries are that it:
Offers state-of-the-art 64-bit relational database processing.
Supports an object-based design that makes it highly virus resistant.
Has proven it can deliver over 99.9% availability on a single system.
Has operated for more than one year without requiring a re-initial program
load (IPL), in hundreds of customer shops.
Can have up to 60 Windows servers in a single system while sharing host
systems disk storage, tape, and CD-ROM resources.
Directly (natively) supports different file structures, such as PC files, UNIX®
files, NetWare files, Domino files (Network File System (NSF)), ASCII files,
and EBCDIC files.
Allows the deployment of Java, ported UNIX applications, Windows,
Domino-based applications, and Linux on a single server.
Integrates leading edge technology. The iSeries server was the first server
with Silicon-On-Insulator (SOI) technology. The POWER4™ and POWER5™
technology-based processors are an extension of that technology at 0.18 and
0.13 micron level.
Offers capacity on demand (permanent or temporary) upgrades to support
immediate and future processor utilization.
Supports up to 254 partitions running IBM i5/OS, and IBM AIX 5L or Linux.
With micropartitioning, allows up to 10 partitions per processor.
Can ship with over 650 processor chips under the covers of a "single" large
system.
Incorporates many autonomic self-healing capabilities.

System concepts

iSeries servers are designed and built as a
hardware and system software components that a business demands. As a
general-purpose business and network system, it is optimized for the required
environment with these unique benefits:
The iSeries architecture is a brilliant, technology-neutral architecture. It
enables businesses to readily exploit the latest hardware and software
