QUESTION NO: 2

A customer is comparing a Power Systems solution with an x86 solution for big data analytics.

Which no-charge IBM analysis is available to justify the value of IBM Power Servers compared to x86 solutions?

A. IT Economics Study (Eagle Study)

B. Performance Navigator

C. System Planning Tool

D. Workload Estimator

ANSWER: D

Explanation:

The IBM Systems Workload Estimator is a web-based sizing tool for IBM Power Systems, System i, System p, System x, IBM Flex Systems, and IBM PureFlex Systems. You can use this tool to size a new system, to size an upgrade to an existing system, or to size a consolidation of several systems. The Workload Estimator (WLE) allows measurement input to best reflect your current workload and provides a variety of built-in workloads to reflect your emerging application requirements. Virtualization can be used to yield a more robust solution. The Workload Estimator will provide current and growth recommendations for processor, memory, and disk that satisfy the overall client performance requirements
