<quote> Here's how the metering system works: the new IBM solution monitors a mainframe's actual energy and cooling statistics (collected by internal sensors); and presents them in real time on the System Activity Display. With this system, a user can now correlate the energy consumed with work actually performed. When the machine reports its maintenance health on a weekly basis, the power statistics may be used. These statistics can be observed real time or also summarized for project or trend analysis. Energy consumption statistics are used for demonstrating cost savings toward electric rebates and programs to reduce data center energy consumption. A Power Estimator Tool is also available for future planning. It calculates how changes in system configurations and workloads can affect the entire energy "envelope" -- including the power needed to both run and cool the machines. For example, a customer adding a single mainframe processor for Linux applications could project the amount of additional energy required before and when the feature is turned on. Normally less than approximately 20 watts are added when an Integrated Facility for Linux (IFL) feature is turned on. Typically, a single mainframe processor with zVM virtualization can perform the work of multiple x86 processors, because of the mainframe's design point for running many mixed workloads at high utilization rates. A single processing chip executing hundreds of workloads efficiently is the key to consuming much less energy than many x86 servers which have many more power consuming components This translates into a simplified infrastructure and cost savings. </quote> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
