This article describes the performance characteristics of IBM® InfoSphere® Information Server in a virtualized environment. IBM®, VMware, and Intel have collaborated to study the runtime performance of IBM InfoSphere® DataStage® 8.7 running in a virtual machine on VMware vSphere 5.0 on a server featuring the Intel Xeon processor E7 family. This study demonstrated that InfoSphere DataStage runs well in a virtualized environment. InfoSphere DataStage was able to scale as the number of virtual CPUs (vCPUs) was increased. Moreover, under normal conditions, throughput was only 2 percent to 10 percent lower for DataStage running in a virtualized environment.

Intel, VMware, and IBM performance teams partnered for the first comprehensive industry study on executing data integration workloads in a virtualized environment. Virtualization has grown to be an important tool in many enterprises for facilitating server provisioning, easing application manageability, and increasing workload availability. However, enterprises also worry about how processing-intensive and input/output-intensive workloads like data integration perform in virtual environments. To demonstrate the viability of virtualizing data integration and to help businesses realize the benefits of running these workloads on virtual machines, Intel, VMware, and IBM sought through this study to guide adoption of IBM InfoSphere DataStage in VMware environments on Intel processors and provide best-practice, tuning, and configuration information.
