IBM intends to undertake a massive server consolidation in an effort to make its data centers more "green."
The computing giant on Wednesday said it will transfer the computing load now on 3,900 servers onto about 30 System z mainframes running Linux.
That transfer will reduce power consumption at IBM's 8 million square feet of data centers by 80 percent over the next five years.
Earlier this year, IBM officially launched what it calls its Big Green Innovations program to offer products and services around environmental conservation and energy efficiency.
Data centers represent large consumers of energy. IBM's internal server consolidation serves as an example of how environmentally friendly practices can also save corporations money, said IBM's Chief Information Officer Mark Hennessy in a release.
Also in a prepared statement, James Stallings, general manager of IBM's mainframe division, said the mainframe--once considered too costly and inflexible--offers substantial power savings benefits over other server platforms.
IBM said it intends to recycle the 3,900 servers that are being decommissioned.
