IBM 'Gas Gauge' Monitors Mainframe Energy Usage, Oct 12, 2007

IBM has added a mainframe gas gauge to more than 1,000 z9s deployed since May 11 to monitor energy usage and cooling statistics.

The consolidation effort began about 18 months ago when TRW moved its ERP system from Unix-based servers to a Linux-on-Dell cluster, "which we found was every bit as fast, and we are able to run those Linux systems at a much lower cost for both procurement and maintenance."

While Windows and Linux may dominate the market for low-cost servers, businesses spent more than $4 billion in the second quarter on Unix servers.

The Israeli government will provide financing and IBM will provide technical assistance to startup companies developing products based on open standards such as Linux and Java.

Hoping to further capitalize in the rapidly growing Linux market, IBM on Monday will expand its fledgling OpenPower server portfolio.
