GSK Consumer Healthcare needed to upgrade an old version of their existing SIMATIC PCS 7. Since GSK had fixed Siemens as a standard supplier and they are already familiar with the SIMATIC Virtualization as a Service (SIVaaS) solution, they wanted to integrate SIMATIC IT into the solution.

Siemens Service experts provided the Industrial Automation DataCenter (IADC) based on SIVaaS, vCentre for PCS 7 and SIMATIC IT. 
In cooperation with Zenith, Italy, Siemens implemented the solution within two steps:  

• Create all the virtual machine for SIMATIC PCS7 and SIMATIC IT 
• Implement a high availability infrastructure with VSAN 

The architecture is designed as below: 

• Host1: OS Client 1 – 10, OS Server 1, Batch Server 1, SIMATIC IT VM1 
• Host2: OS Client 11– 20, OS Server 2, Batch Server 2, SIMATIC IT VM2. OS Server1, Batch Server 1 
• Host3: OS Client 21 – 25, Engineering Station, SIMATIC IT VM3, SIMATIC IT VM1 
• Host4: OS Client 26 – 30, SIMATIC IT VM4, OS Client 1-5 
• Host5: OS Client 31 – 40, OS Client 6-10
