  • Introduction to Virtualization Michael Otey Technical Director Windows IT Pro Magazine
  • What this session covers
    • Types of Virtualization
      • Hardware Virtualization
      • Virtual Machine Virtualization
      • Application Virtualization
    • Future directions in Virtualization
  • Hardware Partitioning
  • Scenarios for Hardware Partitioning
    • Server Consolidation
      • Reduced TCO
      • Increased server utilization
    • Separate production and test environments
    • Application Isolation
  • Hardware Partitioning
    • Physical system is divided into multiple partitions
    • One or more CPUs per partition
    • Full electrical isolation between partitions
    • Redundant hardware components
  • Hardware Partitioning
    • High-end Servers
      • HP Itanium
      • Unisys ES7000
      • Fujitsu PrimeQuest
    • Multiple hardware partitions
      • Up to 8
    • Assignment of physical resource per partition
      • CPUs
      • Memory
      • I/O
    • Cluster “in-a-box” support
  • Hardware Partitioning Summary
    • Can Consolidate multiple servers
      • Reduced administration
    • Requires high-end servers
      • Usually Itanium based
