System z is #1 in the $250K server segment at 32% share and leads #2 HP by more than 14 points.1
Consolidate your workload on a single IBM System z™ mainframe
- Replace UNIX® and x86 processors at a 10 - 28 to 1 IFL ratio*
- Reduce UNIX and x86 OTC SW support costs at a 10 - 28 to 1 ratio*
- Consolidate x86 software licenses at up to a 28 to 1 ratio*
- Leverage the ability of Linux on System z on z10 BC to run many distributed workloads and to consolidate x86 core processors at up to a 28:1 ratio to deliver significant IT Cost savings2
Since System z began its Migration Factory in 2008, we have helped over 150 customers migrate to the System z platform.3

CIOs need to to address their IT infrastructure challenges while reducing costs.
In today's economy, cost reduction can result from improved IT efficiency due to platform selection and by shifting workloads. While our competitors promote mainframe re-hosting with “cost savings”, careful analysis shows this to be a myth. On the other hand; shrinking budgets, server sprawl, power and cooling constraints, and the need to “Go Green” are industry trends that favor the IBM Mainframe. Too good to be true? Check it out yourself.
IBM Mainframe TCO advantages
- Lower TCO - System z is a state-of-the-art efficient platform, which may be able to save up to 80% in total cost of ownership compared to some distributed platforms.1
- Cost Reduction - Consolidate 61 Sun and HP servers to Linux on System z10 and save up to 96% on power and cooling.2
- Simplification - Just a few large virtualized IBM servers may be able to replace hundreds of smaller machines, allowing responsive management of the environment and a nimble support structure. Reductions of 60-90% in number of processors is possible.2
About the tool
The Move Up to IBM Mainframe TCO Challenge tool is developed by, and hosted by, Alinean Inc., a leading ROI/TCO tool company. It provides a preliminary, high level analysis of the estimated potential consolidation savings by switching to current IBM Systems.
- Pre-populated with industry-specific cost data.
- Output highlighting possible financial benefits of the consolidation on a Linux for System z solution.

Distributed consolidation to IBM mainframe success stories
Univar, USA.
Kevin Campbell, Chief Application Architect, discusses Univar USA's reasoning and decision to consolidate and move new workloads from distributed to the IBM mainframe.
Korea Exchange Bank
Korea Exchange Bank and IBM announced the completion of KEB's mainframe migration to IBM System z10 which will enable the bank's credit card business (KEB Card) to create an advanced and smarter IT environment to improve efficiency and customer service.
Under the agreement signed in October 2008, IBM provided KEB Card with three units of the System z10 Enterprise Class (EC), the most advanced IBM System z mainframe with the equivalent capacity of nearly 1,500 x86 servers, with an 85% smaller footprint, up to 85% lower energy costs.
