Energy use and environmental impact are hot topics right now. But it's not just the environment at stake, it's your IT budget. By "going green" with the energy efficient IBM System x servers featuring Intel Xeon processors, you can cut your energy costs by half and save floor space to make room for future growth.
Get the details on these benefits and many others in this Solution Brief from IBM.

Overview Do you remember how much your last server cost you overall? With energy prices on a steep climb, soon the cost to power and cool a server over its life span could equal its purchase price. According to IDC, over the next two years you'll spend 70 cents in power 1and cooling for every dollar you spend on hardware. Unless you expect energy costs to drop in the near future, it's quite likely that over the next five years your energy costs could end up exceeding your hardware costs. ® T ® ®By "going green" with energy-efficient IBM System x servers featuring Intel Xeon processors, you can win back control of your IT budget-and win the battle with data center power constraints. Go green to: . Potentially cut your energy costs in half or better-or achieve greater performance 2within the same energy envelope . Expand IT without exceeding data center power limits . Save floor space for future growth . Leave your competitors to struggle with the energy crunch Figure 1 demonstrates the major performance-per-watt improvements over time, progressing from single- to dual- to quad-core processors:
Figure 1. 8X performance enhancement The energy cost-savings of going green with System x servers and Xeon processors can be tremendous. IBM economic analysts estimate that the typical 25,000 sq. ft. data center, spending $2.6M on energy each year, can cut costs in half by using green technologies and consolidating servers. With a return of that size you can invest in more strategic IT projects while your competitors continue to struggle with their power bills.

Solution Brief: Go Green with IBM System x Servers and Intel Xeon Processors Page 3 Going green can also help you increase IT capacity. The pivotal question is: Can you expand within your current floor space safely, without overextending the power and cooling thresholds of your facilities? The answer? Go green for a denser infrastructure. Consolidate your infrastructure on the latest high-performance, energy-efficient System x servers and Xeon processors that place minimal demands on power and cooling. You can simultaneously increase IT capacity, free up floor space and stay within the power and cooling limits of your data center. Ultimately, going green with IBM System x servers and Intel Xeon processors translates into minimizing your company's carbon footprint and much more: the cost savings and room for IT growth that sustain a competitive business edge.
More Performance Per Watt The story of System x energy efficiency starts with the IBM-designed power supply. Typical industry-standard power supplies are only 60-70% efficient. This means 300-400 watts of every kilowatt consumed is expended as waste heat, rather than used productively. By contrast, some System x rack servers are as much as 91% energy-efficient. Therefore, only 90 watts are wasted out of each kilowatt. To fully exploit this efficiency and help you maximize computing performance per watt, IBM gives you the option of equipping your servers with leading performance and performance-per-watt quad-core Intel Xeon processors-including a new 50W processor option (available on selected models). TWith enhanced Intel Core microarchitecture technologies, the Xeon processors give you substantial performance gains over previous-generation processors without increasing energy consumption. Key microarchitecture innovations, incorporated into the latest System x models, include: . New 45nm process technology to deliver higher levels of performance and density with fewer cooling challe... [download for more]
