IBM mainframes central to 'Big Green Linux' initiative

Much like COBOL, The imminent death of the mainframe computer has been predicted "really soon now" for at least the last 20 years. The efficiency of putting massive amounts of computing power together with enormous communications bandwidth is once again being revealed in the search for more energy efficient computing.

IBM launches 'Big Green Linux' initiative - ZDNet UK:
"The 'Big Green Linux' initiative is part of the wider Project Big Green, launched in May, which is specifically aimed at helping IBM and its clients reduce data-centre energy consumption. IBM kicked off the new initiative at the opening of the LinuxWorld and Next Generation Data Center trade shows in San Francisco, accompanied by Novell and the Linux Foundation.
The initiative doesn't centre on any one product announcement, but instead highlights several new IBM systems and projects aimed at Linux-based energy efficiency.
. . .
IBM said last week it would take its own advice, with a plan to consolidate about 3,900 of its own servers onto about 30 System z Linux mainframes, cutting energy consumption by about 80 percent in the process."
