POWER5* processor-based systems. For your convenience, the System Calculators Web page (http://publib. boulder.ibm.com/infocenter/systems/ scope/hw/topic/iphdl/systemcalculators. htm) provides links to both tools. The Energy Estimator is the follow-on tool to the Power Load Calculator for estimating energy requirements for IBM systems using POWER6 processors and future processors. Additionally, the Energy Est imator ex pands on prev iously available energy-estimation capabilities by supporting expansion disks. ar r ive at a recommended solution involving an IBM Power Systems or POWER6 processor-based system on the Selected System screen, you can use the new “Energy estimate” option to generate an estimated energy value for the recommended system configuration (Figure 4, page 38). The Workload Estimator also supports sizing requests dealing with multiple systems, partitions, operating systems and time intervals. You can coordinate these features using the functions on the Workload Selection screen. To use the Workload Estimator, select one or more workloads and answer a few questions Integration With the Workload Estimator The IBM Systems Workload Estimator is a Web-based sizing tool for IBM Power Systems, System i, System p, and System x* servers. The Workload Estimator can recommend a system model including processor, memory and disk requirements necessary to handle a user-defined workload with reasonable performance expectations. The 2008.4 version of the Workload Estimator, released in October 2008, includes integration with the Energy Estimator. This lets you generate an energy estimate for system configurations recommended by the Workload Estimator. The Workload Estimator is available at the IBM Systems Workload Estimator Web page (www.ibm. com/systems/support/tools/estimator). You can use the Workload Estimator to size a new system, size an upgrade to an existing system or consolidate several systems. The tool provides input capability for measured data to reflect your current workload and provides a variety of built-in workloads to reflect your emerging application requirements. You can also incorporate virtualization to yield a more robust solution by using various types of partitioning and virtual I/O. The Workload Estimator provides current and growth recommendations for proce s sor, me mor y a nd d i sk that satisf y the overall customerperformance requirements.
