Executive Summary
Forward-thinking enterprises that want to achieve
optimal performance, reduce total cost of ownership
(TCO), and avoid end-of-life issues on proprietary
Unix platforms are electing to migrate their SAP®
Business Suite applications to Linux x86 servers.
To ensure a successful transition, Dell and SAP have
brought to market an integrated solution comprising
high-performance servers and software and a market
leading database capable of reducing SAP Business
Suite customers’ TCO by 50% or more – freeing up
much-needed funds for IT innovation. And with
Dell ZeroIMPACT Migration, companies can reduce
potential risks and downtime associated with a
transition to Linux – helping them realize immediate
performance gains and an attractive time-to-value.

According to IDC, SAP ASE delivers 28% lower TCO compared
to other relational databases it studied.7 These compelling
savings are realized in three key areas: licensing fees,
maintenance costs, and storage costs. (See Figure 4.)
