Getting Started

Virtualization technologies are becoming a high priority for IT administrators and managers, software and systems engineers, plant managers, software developers, and system integrators.

Mission-critical operations in both small- and large-scale organizations demand availability—defined as the ability of the user community to access the system—along with dependable recovery from natural or man-made disasters. Virtualization technologies provide a platform for High Availability solutions.

The purpose of this guide is to help you to implement Manufacturing Execution System (MES) in a virtualized environment, including:

• Implementing High Availability (Live Migration and Failover) using VMware technology

• Implementing High Availability (Live Migration and Failover) using Windows Server virtualization technologies such as Hyper-V

This chapter introduces and defines virtualization concepts.

Subsequent chapters describe how MES was configured in a virtualized environment for a High Availability qualification. They also describe test results for the suggested configurations using both VMware and Hyper‑V technology.

Subsequent chapters also provide test and performance metrics for a wide variety of system configurations, including Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
