ABB has chosen VMware ESX. It can be used in 800xA systems to combine multiple 800xA server applications on a single computer. The total number of physical computers required in an installation is reduced significantly. This also reduces the required space for computers, hardware acquisition cost for computers and cabinets and operating expenses (such as energy costs).
System 800xA can achieve higher availability and functionality with the use of less hardware when installed in a virtualized environment. This is achieved due to System 800xA’s software architecture and inherent server redundancy. Maintenance is also less resource dependent due to centralizing access through the VMware console. Via this console, the status of each server and virtual switches is presented and can be accessed from a centralized location.
