The Mainframe Returns! Per IBM and HP

Recently, IBM announced their Project Big Green initiative and HP announced its own datacenter consolidation project , why Mainframes are more energy efficient than distributed servers. And since Mainframes can now run Linux why not. Using Mainframes you then create virtual servers for individual clients and projects.

Energy savings could be as much as 80 percent over distributed servers. In IBM's case that is as much as $250 million in overall costs, by replacing the servers with its System z mainframes running the open-source Linux operating system.

That's big money, and if the numbers hold up, IBM and HP will be selling a whole lot more servers, and we'll all be doing our business computing on virtual Linux servers, running from mainframes in a relative few Data Centers.

But, I doubt us Developer/Tester/DBA types will be seeing any of the savings in our paychecks, that money will go to the MBA's.
