VMware Esx Short Presentation

  1. 1. VMware ESX Server Datacenter-Class Virtual Infrastructure for Mission-Critical Environments Copyright © 2005 VMware, Inc. All rights reserved.
  2. 2. VMware Mission <ul><li>Transform industry standard server and desktop computing through virtualisation </li></ul>Copyright © 2005 VMware, Inc. All rights reserved. Application OS Hardware Virtualisation Hardware App OS App OS 70% Reduction in Operating Costs 40% Reduction in Hardware and Software Costs Increased Reliability & Responsiveness Greatly Enhanced Business Continuity Increased Utilisation & Return on Assets Application OS Hardware
  3. 3. What is Virtual Infrastructure? Copyright © 2005 VMware, Inc. All rights reserved. Infrastructure is what connects resources to your business Virtual infrastructure is a dynamic mapping of your resources to your business Result: d ecreased costs and increased efficiencies and responsiveness VMware technology provides a thin virtualisation layer that encapsulates operating systems and applications into portable virtual machines
  4. 4. What is Virtualisation? Copyright © 2005 VMware, Inc. All rights reserved. Hardware Application Operating System With Virtualisation Without Virtualisation <ul><ul><li>VMware provides hardware virtualisation that presents a complete x86 platform to the virtual machine </li></ul></ul><ul><ul><li>Allows multiple applications to run in isolation within virtual machines on the same physical machine </li></ul></ul><ul><ul><li>Virtualisation provides direct access to the hardware resources to give you much greater performance than software emulation </li></ul></ul>
  5. 5. Three Key Properties of Virtualisation Copyright © 2005 VMware, Inc. All rights reserved. <ul><li>Partitioning </li></ul><ul><li>Run multiple operating systems on one physical machine </li></ul><ul><li>Fully utilise server resources </li></ul><ul><li>Support high availability as shared data is cluster-ready for failover and redundancy </li></ul><ul><li>Encapsulation </li></ul><ul><li>Encapsulate the entire state of the virtual machine in hardware-independent files </li></ul><ul><li>Save the virtual machine state as a snapshot in time </li></ul><ul><li>Re-use or transfer whole virtual machines with a simple file copy </li></ul><ul><li>Isolation </li></ul><ul><li>Isolate faults and security at the hardware level </li></ul><ul><li>Dynamically control CPU, memory, disk and network resources per virtual machine </li></ul><ul><li>Guarantee service levels </li></ul>
  6. 6. VMware ESX Server Copyright © 2005 VMware, Inc. All rights reserved. <ul><li>ESX Server is a virtual machine platform with a bare-metal architecture for highest possible performance </li></ul><ul><li>Lean virtualisation-centric VMkernel delivers complete control over hardware resources </li></ul><ul><li>Supports dynamic allocation of computing resources </li></ul><ul><li>Highly available, fault-tolerant and secure design </li></ul><ul><li>Supports both scale-up and scale-out strategies </li></ul>Datacenter-Class Virtual Infrastructure for Mission-Critical Environments
  7. 7. Bare-Metal vs. Hosted Virtualisation <ul><li>Bare Metal </li></ul><ul><li>Hosted </li></ul>Copyright © 2005 VMware, Inc. All rights reserved. <ul><li>Device support is inherited from host operating system for maximum hardware compatibility </li></ul><ul><li>Virtualisation installs like an application rather than like an operating system </li></ul><ul><li>Can run alongside conventional applications </li></ul><ul><li>Maximum performance with lowest overhead using certified hardware </li></ul><ul><li>Highly efficient direct I/O pass-through architecture for network and disk </li></ul><ul><li>Highly secure micro-kernel virtualisation layer— only 100Ks of lines of code versus 10–25 million lines of host operating system code </li></ul><ul><li>Advanced features like VMotion available </li></ul>(ESX Server) (Workstation, ACE & GSX Server)
