Introduction

Businesses have the increasing challenge of improving the performance of their system infrastructure and delivering more, while balancing the pressures of reducing overall costs. At the same time, existing servers and equipment are aging such that they cannot support the growing capacity and performance demands. Businesses are increasingly seeing their legacy systems reach the end of life, either through expiring leases or vendors ceasing to support the systems. The ongoing support costs of existing machines and platforms must be analyzed to ensure capacity for potential future growth. The competitive marketplace leaves no room for falling behind or for accruing extraneous costs. In light of this, companies have to consider how to obtain a desirable return on investment (ROI), either through staying on the same platform or considering an alternative platform.

When evaluating what platform offers the best ROI, the following should be considered:

- How to reduce total cost of ownership (TCO)? Reduce manageability costs? Reduce license costs? Reduce support costs?
- How to improve performance and quality of service?
- How to allow for future growth and flexibility?

The challenge comes in evaluating and balancing all these demands to obtain the best ROI. Increasingly, businesses are looking to an Intel® Architecture-based platform running the Linux* operating system to reduce their TCO and boost performance, without compromising the availability and reliability that is needed for enterprise applications.

This document describes items to consider when migrating from a RISC-based environment to Linux* running on Intel architecture. This is not a how-to or integration guide; rather this paper documents some examples of other companies who have performed such a migration and some of the tools that have been used.
