Rockwell Automation supports virtualisation with VMware Ready software
Virtualisation fundamentally changes the way hardware resources are used. It works by inserting a thin layer of software called a ‘hypervisor’ directly on the computer hardware, or on a host operating system. This layer contains virtual machines that can be transparently allocated to hardware resources when and where they are needed. Multiple operating systems run concurrently in isolated virtual machines on a single physical computer and share hardware resources with each other.
Today’s x86 computer hardware is designed to run a single operating system environment. This 1:1 ratio results in most workstations being vastly under-utilised committing financial resources to purchase, operate and maintain more CPUs than are necessary, wasting valuable floor space, increasing energy consumption, and tying up spending capital.
By encapsulating an entire machine, including CPU, memory, operating system and network devices, a virtual machine is completely compatible with all standard x86 operating systems, applications and device drivers. Virtual machines can be run on any virtualisation-enabled physical server, creating a pool of computer resources that helps ensure the end-user’s highest-priority applications will always have the resources they need without wasting money on excess hardware only needed for peak times.
Virtualisation technology also simplifies the distribution of bundled offers, such as the Rockwell Automation PlantPAx Process Automation System, and extends the life of software. Rather than upgrading software every two to three years or testing ‘old’ Windows versions, virtualisation technology helps enable end-users to run the same software on a particular PC or operating system for more than 10 years.
“One of the primary issues that manufacturing end-users continuously cite is the great disparity between the long product life cycle of their automation hardware versus the short product life cycle of their automation software,” said Craig Resnick, research director, ARC Advisory Group. “VMware Ready products extend the product life cycle of automation software, as well as help manufacturing end-users fulfil their energy savings and sustainability objectives, through the more efficient utilisation of their automation infrastructure. This results in improved key performance indicators (KPIs), a lower total cost of ownership (TCO), and a shorter return on investment (ROI).”
Most Rockwell Automation configuration, human interface and information products, such as the Rockwell Software RSLogix, FactoryTalk View, FactoryTalk Historian and FactoryTalk VantagePoint software, are supported when running on the VMware platform. Support for a virtual environment is based on the user’s Rockwell Automation service agreement, as well as product documentation for the operating system running in the virtual environment.
VMware delivers solutions for business infrastructure virtualisation that enable IT organisations to energise businesses of all sizes. With the industry-leading virtualisation platform—VMware vSphere—customers rely on VMware to reduce capital and operating expenses, improve agility, ensure business continuity, strengthen security and go green. With 2008 revenues of $US1.9 billion, more than 150,000 customers and 22,000 partners, VMware is the leader in virtualisation, which consistently ranks as a top priority among CIOs. VMware is headquartered in Silicon Valley with offices throughout the world and can be found online at www.vmware.com.
