IBM® z/VM® V6.3 extends the mainframe virtualization platform to help you reshape and derive more value from your experiences. z/VM V6.3 is designed to offer:

• Improved economies of scale with z/VM support for 1 TB of real memory
  
  • Better performance for larger virtual machines
    • Quadruples memory scalability while continuing to maintain nearly 100% resource utilization
  • Reduced LPAR sprawl for additional horizontal scalability
    • Considerably more virtual machines can be consolidated into a single LPAR, depending on workload characteristics.
  • Reduced administrative expense for managing a smaller number of large capacity z/VM host servers
• Improved performance with HiperDispatch
  • More efficient utilization of CPU hardware resources underneath multiple layers of virtualization running multiple and diverse workloads

Today's z/VM provides a highly secure and scalable enterprise cloud infrastructure and an environment for efficiently running multiple diverse critical applications with support for more virtual servers than any other platform in a single footprint. Enhancements that provide improved scalability and better price performance strengthen z/VM as a foundation for optimized workload deployment with reduced costs per virtual serv
