Continuing its push into greener computing
, IBM today announced the launch of its so-called "Mainframe Gas Gauge," which promises to let its server customers monitor their exact energy consumption in real time. What's more, IBM also announced that it'll begin publishing typical energy consumption figures for its z9 mainframe systems, following a recent EPA report that advised server makers to do just that. That data will be collected from some 1,000 servers around the world (a process that actually began in May), each of which employ sensors to monitor actual energy and cooling statistics, giving IBM enough info to determine the average watts per hour consumed and the total watts per unit. Individual server users will also get weekly reports on their machines' energy consumption in addition to the real time data, and they'll be able to make use of a new "Power Estimator Tool" to help them determine the most efficient means of expanding their server farms.
