Case Study

The challenge

To reduce complexity – consolidation of Blade Server infrastructure with 150 servers

To cut costs – modern server hardware and virtualization

To improve service for users – streamlined operational processes and improved application availability

To commit to green IT – energy savings and efficient use of advanced technology

Green IT Project Report: consolidation and virtualization in x86 environments

Wincor Nixdorf boosts performance and

cuts power consumption by 75 percent

» It pays to work with innovative technology and a leading IT

provider: energy savings and performance benefits combine withvirtualization technology to permit significant enhancement of 

IT operations. «Dietmar Leineweber, Manager Basic IT Infrastructure with Wincor Nixdorf 

The solution

Wincor Nixdorf’s Padergreen Project, which involved the

replacement of 150 Blade Servers, clearly showed that a

combination of current server technology and

virtualization technology is the best way to take full

advantage of potential for savings. Fujitsu determined

the optimal mix for Green IT by

comparing the Blade Server environment in place with a

target configuration consisting of current PRIMERGY 

Blade Servers with VMware under actual customer

operating conditions. In the case of Wincor Nixdorf, it was

found that it would be possible to reduce the number of 

servers required by more than 80 percent and cut energy

consumption by 75 percent. In addition, Wincor Nixdorf was

also able to achieve significant improvement in performance

at the operational level and reduce administrative expense.

Wincor Nixdorf ranks among the world’s leading providers of IT solutions and services for

banks and retail operations. The group has subsidiaries in 37 countries and is present in a total

of some 100 countries with a total of more than 9,000 employees.

The project

How much energy is it possible to save and how much improvement can be achieved in IT operation through

modernization of x86 server infrastructures? Wincor Nixdorf wanted to find out and turned to Fujitsu for theanswer. When the Padergreen Project was launched, the Wincor Nixdorf Paderborn data center

had a modern, extensively standardized infrastructure in place with systems that had been in operation for two

years. Applications and services were supported by 150 PRIMERGY Blade Servers from different generations. However,

workload analysis showed that most smaller and medium-sized “VMware ready” application servers were being

used at less than 10 percent of capacity on average and at only 50 percent during peak periods. Only a single system,

the one running the management software for the entire data center, had a greater workload. All in all, only a

quarter of the available compute capacity was actually required for normal operation. That meant there was

considerable potential for improvement in the use of the capacity of the physical hardware. Wincor Nixdorf is

now running an average of about six virtual machines on each physical server. The performance-related power

consumption of six old server blades was compared with a new model based on six virtual machines and the

energy saving was then calculated for each fully populated chassis. However, the number of virtual machines perESX server will be steadily increased in the future for performance reasons.

A record of success

The improved performance and energy efficiency of the new server technology – in this case PRIMERGY BX600 S3

with BX620 S4 blades – in combination with virtualization technology produces the best results. Wincor Nixdorf’s

systems engineer Mark Rappsilber says: “The use of current servers permits an impressive reduction in hardware.

Enormous savings result when efficient systems are paired with virtualization.” High-performance, energy-efficient

hardware represents the key to such savings. Taking into account the security guidelines of Wincor Nixdorf, it was

possible to reduce the size of the server farm by a factor of 6. With VMware ESX Server, Wincor Nixdorf can now

make optimal use of available compute power. All in all, that adds up to a reduction of up to 75 percent in energy

costs. Depending on the price per kWh, annual savings for each fully populated PRIMERGY BX600 Blade Server

system can come to between 7,000 and 11,000 Euro. This very positive energy balance is accompanied by further

benefits. For example, capital expenditure and maintenance expense are lower, and the infrastructure to be

managed is leaner. In addition, users benefit from high-availability management of applications and services and

demand-based performance. Dietmar Leineweber, manager Basic IT Infrastructure, concludes: “It’s worth investing

in Green IT because it means improved efficiency and performance, less hardware, lower costs and less impact on

the environment.”
