3 Today s Agenda Current IT Challenges Rising IT costs and decreasing operational efficiencies Virtualization Concepts Hypervisor types, core virtualization features, basic design Architecture and Components VMware Infrastructure 3, Microsoft Hyper-V, and Citrix XenServer 5 Management Management software and feature comparison Deployment Guest O/S support, software versions, and deployment examples

4 Your IT Challenges Rising Costs Adding New Servers Data Center Power Data Center Cooling Server Administration Hardware Upgrades Backup and Recovery EFFICIENCY Lower ROI Avg Server Utilization: 5-10% of Processor 25-50% of Memory <1% of Disk Throughput Capacity <1% of Network Adapter Throughput Less Manageability Complexity increases as servers multiply The number of apps continues to grow Heterogeneous mix of HW, models, O/S, configs IT COSTS Lower Efficiency More time spent on reactive tasks like server provisioning, configuration, and monitoring Less time spent on proactive, strategic IT projects

5 Today s Agenda Current IT Challenges Rising IT costs and decreasing operational efficiencies Virtualization Concepts Hypervisor types, core virtualization features, basic design Architecture and Components VMware Infrastructure 3, Microsoft Hyper-V, and Citrix XenServer 5 Management Management software and feature comparison Deployment Guest O/S support, software versions, and deployment examples

6 Virtualization Concepts One Physical Server = Multiple VMs Before Virtualization After Virtualization Software tied to hardware Single OS image per machine One application workload per OS HW independence of O/S and apps VM can be provisioned to any system Manage O/S and apps as one unit Inflexible, Costly Infrastructure Flexible, Affordable Infrastructure

7 Virtualization Concepts Type 1 vs. Type 2 Virtualization Type 1 (Native or Bare-Metal) Hypervisors run directly on the host's hardware as a hardware control and guest o/s monitor Guest operating system runs on another level above the hypervisor Type 2 (Hosted) Hypervisors run within a conventional operating system environment Guest operating systems run at the third level above the hardware

8 Virtualization Concepts Type 1 Beats Type 2 Performance Examples of Type 1 Hypervisors Apple Bootcamp Citrix XenServer Microsoft Hyper-V Oracle VM Parallels Server Sun's Logical Domains Hypervisor VMware ESX Server

9 Virtualization Concepts Core Virtualization Features 1. Encapsulation Servers are developed and saved into a few files (Virtual Machine) Virtual Bios = Nvram Text file defining its configuration = w2k.vmx Disk file that contains its data = w2k.vmdk An entire Server can be managed as a simple collection of data files Entire state of the VM is encapsulated including: Memory Disk images I/O device state Physical Server Encapsulation Apps System Data = File Encapsulate entire system as simple files

10 Virtualization Concepts Core Virtualization Features 2. Hardware Independence Portability Across Different x86 Hardware Utilize Different hardware platforms Server can be transferred through Time and Space Time: Store Server in a file Space: Transfer Server over a network Rapid Server Provisioning Hardware Independence Run a virtual machine on any server without modification

11 Virtualization Concepts Core Virtualization Features 3. Isolation Each virtual machine is isolated from others Totally separate OS, registry, applications and data files Immune to guest OS crashes, viruses or corruption Fault, performance, and security isolation CPU, RAM, Disk, and Network resource controls* Guaranteed service levels* Isolation App OS Batch Job App OS DR Test App OS Virtual Infrastructure Each VM isolated from other VMs

12 Virtualization Concepts Core Virtualization Features 4. Partitioning Dynamically map computing resources VM based on business requirements Lower IT costs through increased efficiency, flexibility and responsiveness Provision new services and change the amount of resources dedicated to a software service Treat your Data Center as a single pool of processing, storage and networking power Partitioning % Utilization Run multiple VMs simultaneously on a single server

13 Virtualization Concepts Virtualization Building Blocks Logical Resource Pool

14 Virtualization Concepts Considering Virtualization? Keep the Following in Mind: Strategy (replace, expand) Which systems to virtualize Operating systems involved Hardware platforms Administrative issues Hardware reuse, replacement Licensing issues Legacy software considerations Additional infrastructure requirements Prototype testing Migration Commissioning

Once the vdisk is available, the target device no longer needs its local hard drive to operate; it boots directly across the network. Provisioning Server streams the contents of the vdisk to the target device on demand, in real time, and the target device behaves as if it is running from its local drive.
