This efficiency results in significantly reduced costs, with improved service levels and security. PowerVM also offers a reliable and resilient virtualization environment, built on the advanced RAS (reliability, availability and serviceability) fea- tures, extreme scalability and leadership performance1 of the IBM Power Systems platform, based on the outstanding POWER7® processors.
