Selecting A Server-Value of S/390

An IBM Redbooks publication


This IBM Redbooks publication is designed to help you select the most appropriate server platform for a business application or set of applications.
The book discusses the issues you should consider and how different platforms address those issues. It also gives you an appreciation of an S/390 server as a possible solution to your requirements.

The purpose of this book is to help you:
- Understand the key items to consider when choosing a large server
- Compare different platforms, especially S/390 and traditional UNIX servers (S/390 is also a UNIX server)
- Learn the advantages of the S/390 platform
- Appreciate all the cost implications of your platform choice

A sample cost comparison of S/390 and traditional UNIX servers and a checklist of key questions to consider are included.

This book is relevant for people looking at:
- Realignment of information technology with their business goals
- Local area network (LAN) or application consolidation
- Applications that have traditionally run on host computers
- New applications
- Data mining
- Query applications
- UNIX servers
- Internet servers

In the context of this book, S/390 refers to IBM S/390 servers running OS/390. Other IBM operating systems, such as VM/ESA and VSE/ESA also support IBM S/390 servers and provide significant value for customers when compared to other platforms. These other environments are beyond the scope of this book.
