IBM's Project Big Green Spurs Global Shift to Linux on Mainframe

IBM has announced plans to consolidate its data center from 3,900 computer servers onto about 30 System z mainframes. The initiative is part of Project Big Green, a broad commitment that IBM announced in May to sharply reduce data center energy consumption for IBM and its clients. According to IBM, the new server environment will consume approximately 80 percent less energy than the current set up and the company expects
significant savings over five years in energy, software and system support costs.
