System: Linux* virtual machines on z/VM*, AIX* LPARs on the POWER7* processor-based blade and Linux virtual machines on a kernel-based v ir tual machine (K V M ) on the forthcoming IBM x86* blade1. Virtual machines were created and added to each virtualization platform, and key metrics like throughput, response time and CPU utilization were plotted against the number of virtual machines. We applied statistical calculations to CPU-utilization data, measured in the benchmark runs, to accommodate realworld variations in workload dem a nd . The r e su lt i ng benchmarks showed what consolidation ratios can be achieved for each class of workload on each of the three virtualization platforms. For a detailed description of the methodology, download the IBM whitepaper, “A Benchmark Study on Virtualization Platforms for Private Clouds,” under the heading “A Statistical Model to Account for Workload Variability” (http://bit.ly/virtual4privatecloud). Next, we determined the cost of acquisition for each deployment option. The three-year TCA of each deployment option includes the hardware and software acquisition costs, three-year hardware maintenance costs and three-year software license costs. This allowed us to divide the cost of the deployment platform (the container) by the number of workloads that can be deployed to get the cost per workload. The deployment option that yields the lowest cost per workload is selected as the best-fit deployment option for that class of workloads. We found the heavy I/O distributed workloads can be best fit onto a 32-way z/VM LPAR on the zEnterprise 196 central processing complex (CPC). The compute-intensive (heavy) distributed workloads are best fit onto the POWER7 processor-based blades and the light distributed workloads are best fit onto the x86 blades.

A Best-Fit Approach T
he diverse workloads in today’s businesses have unique system requirements. For example, a banking customer may run core banking applications as well as financial-forecasting applications. The core banking applications need high qualities of service like scalability and availability, but the forecasting application requires support for fast processing of complex queries. A onesize systems approach will not fit all. The zEnterprise System unifies the best of mainframe and blade technologies. It couples the latest generation of the System z* central processing complex (CPC) to select POWER7* and Intel* technology-based blades. What makes this combination unique is that the zEnterprise Unified Resource Manager software enables mainframe-based management across the platforms (see right). This enables customers to deploy different workloads onto different environments based on the characteristics and requirements of these workloads, but retain a single point of management. The deployment options include z/OS*, Linux* running native on the CPC, Linux running as a virtual machine on z/VM*, AIX* partitions on the POWER7* blade, virtual machines on the forthcoming IBM x86* blade , specialized optimizer

Technology Unification
IBM zEnterprise 196 (z196)
Optimized to host large-scale database, transaction and missioncritical applications Fastest enterprise processor (based on 5.2 GHz clock speed) Efficient platform for large-scale Linux* consolidation Capable of massive scale-up

zEnterprise Unified Resource Manager
Unifies management of resources, extending IBM System z* qualities of service end-to-end across workloads Part of the IBM System Director family, provides platform, hardware and workload management

zEnterprise BladeCenter Extension (zBX)
Selected IBM POWER7* blades and IBM x86 blades for thousands of AIX* and Linux applications High-performance optimizer appliances to accelerate time to insight and reduce cost

appliances, etc. A best-fit deployment results in the lowest acquisition cost per unit of work done.
