In automation technology the advantages of virtualization shall also be reached. Description of the automation task Typical configurations of systems shall be virtualized. Which infrastructure and which configuration steps are necessary in order to virtualize plants? 1.2 Virtualization requirements The requirements for virtualized computers are identical to those for real computers. During runtime no difference to real computers shall be noticeable. 8 / Virtualization V1.0, Entry ID: 49368181
2 Automation Solution 2.1 What is virtualization? 2 Automation Solution 2.1 What is virtualization? 2.1.1 Definition Virtualization Virtualization refers to the runnable mapping of one or several computers on a real computer. On a real computer a special software runs which provides one or several virtual computers parallel. The virtual computers can be started and stopped independent of each other. Even after a crash only the respective virtual computer is affected.

2 Automation Solution 2.1 What is virtualization? 2.1.2 Advantages of the virtualization Reduction of the hardware costs Reduced HW costs through consolidating several physical computers. (The cost reduction results from a better hardware utilization.) On the client side more cost-efficient hardware is possible. Expanded application areas: SIMATIC Thin solutions (PC, Panel, mobile PDA). Reducing the time expenses for service and maintenance Shorter times for updates and backups since these are executed from a central place Reduced maintenance cost and time through central administration. configuration by means of remote management tools. Increased safety Increased safety through remote access and centralized rights management. Virtually no possible attacks for Thin s, central protection at the virtual server. Increased availability Exchange of hardware at the virtual server is possible during runtime. 1 Increased flexibility Additional clients can be added on demand simply by starting a further VMware session. Additional clients for special tasks can simply run in the background: RDP 2 /VNC 3 -solutions for remote or mobile accesses Provision of substitute computers as virtual systems, e.g. during maintenance of a system a substitute system can be used instead. 1 When using the respective virtualization hardware. 2 Windows Remote Desktop protocol: There is a number of possible clients for various operating systems of for mobile devices. (The server is located in the Windows operating system.) 3 Virtual Network Computing: alternative option for remote control of operating systems. (A server is required on the operating system.

6 Diagnostic Capabilities 6.1 Diagnosis with VMware vsphere 6 Diagnostic Capabilities 6.1 Diagnosis with VMware vsphere General information The vsphere client does not only enable configuring the virtual machines (guest systems) but also monitoring the ESXi server and the individual virtual machines (guest computers). Monitoring options Various curve displays are possible in the vsphere client: Main memory load Operating state CPU load Hard disk Network load Procedure in detail Table 6-1 No. Step/Action 1. Logging on at the ESXi server Start your VMware VSphere client. The log-on dialog appears: Enter the IP address of your virtualization server and your user data. The vsphere client starts. 2. Navigate to the ESXi server diagnostics In the navigation tree you select entry at the top. (The virtualization server) Then close the Performance tab. A diagram appears with the gradient of the performance data. 3. Adjust the diagnostics of the ESXi server To monitor the values used at these measurements please proceed as follows: In the top most area you click on Trend settings. The Adjust performance trend dialog appears. Monitoring the work memory In the Trend settings tree you extend the RAM entry. In RAM you click on Realtime. In the Performance logs you unselect everything and then activate only active. Confirm with OK. In the diagram you can now monitor the active work memory. Monitor the CPU load In the Trend settings tree you extend the CPU entry. In CPU you click on Realtime. In the Performance logs you unselect everything and then activate only usage. Confirm with OK. In the diagram you can now monitor the CPU load. 86 / Virtualization V1.0, Entry ID: 49368181

6 Diagnostic Capabilities 6.2 Diagnosis in the virtual system 6.2 Diagnosis in the virtual system Procedure in detail The Windows operating system provides a tool for diagnosis, the Windows Performance monitor Table 6-2 No. Step/Action 1. Starting the tool Click on Start > Run.... The Run... dialog appears. Enter Perfmon and click on OK. The monitoring tool starts. 2. Adjusting the performance logs Remove all performance logs in the bottom right area. Click right in this area. Select Add performance logs... from the menu. The Add performance logs dialog appears. In order to display the CPU load as a percentage you select the Processor data object and select the performance indicator % Processor Time. Select _Total as the instance. Click on Add. To display the work memory assignment you select the Memory data object and select the Committed Bytes data object. Click on Add and close the dialog with Close. Note It is a problem to display both values simultaneously in one diagram. The scaling of the axis differs. For an optimal display the scaling must be adjusted via the Properties button and the Graphics tab. 88 / Virtualization V1.0, Entry ID: 49368181
7 6BGlossary 7 Glossary ESXi This is a product by VMware. The software has/is an own operating system and provides virtual systems with work space. The software is used for virtualization on the server side. Refers to virtual system. Refers to virtualization server. Hyper Threading A technology for better processing of commands for the processor. One process core therefore appears as 2 process cores. Management Station Refers to a PC which takes on the configuration, maintenance and monitoring of one or several virtualization servers. Applications VMware Converter or vsphere can be used here. Virtualization server (and virtual system) Refers to the real PC on which the VMware ESXi runs and who provides its resources to virtual systems. Computers which run within the VMware ESXi software are virtualized systems. Virtual hardware Real resources are not provided to the virtualized systems directly to enable joint usage. Such jointly used hardware can be network cards, process cores or hard disks. This can be proportionally and jointly by all virtualized systems. Virtual network A network which only exists within a virtualization server and enables a communication option with several virtual systems (within one virtualization server). Virtual processor core A processor core provided to the virtual machine. VMware A company and manufacturer for virtualization software. VMware vcenter Converter A product by VMware for converting, transferring and creating of virtual systems. VMware Workstation A product by VMware for creating and using virtual systems on already existing operating systems. / Virtualization V1.0, Entry ID: 49368181 89
