    • VMware ESX Server Datacenter-Class Virtual Infrastructure for Mission-Critical Environments Copyright © 2005 VMware, Inc. All rights reserved.
    • VMware Mission
      • Transform industry standard server and desktop computing through virtualisation
      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
    • 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
    • What is Virtualisation? Copyright © 2005 VMware, Inc. All rights reserved. Hardware Application Operating System With Virtualisation Without Virtualisation
        • VMware provides hardware virtualisation that presents a complete x86 platform to the virtual machine
        • Allows multiple applications to run in isolation within virtual machines on the same physical machine
        • Virtualisation provides direct access to the hardware resources to give you much greater performance than software emulation
    • Three Key Properties of Virtualisation Copyright © 2005 VMware, Inc. All rights reserved.
      • Partitioning
      • Run multiple operating systems on one physical machine
      • Fully utilise server resources
      • Support high availability as shared data is cluster-ready for failover and redundancy
      • Encapsulation
      • Encapsulate the entire state of the virtual machine in hardware-independent files
      • Save the virtual machine state as a snapshot in time
      • Re-use or transfer whole virtual machines with a simple file copy
      • Isolation
      • Isolate faults and security at the hardware level
      • Dynamically control CPU, memory, disk and network resources per virtual machine
      • Guarantee service levels
    • VMware ESX Server Copyright © 2005 VMware, Inc. All rights reserved.
      • ESX Server is a virtual machine platform with a bare-metal architecture for highest possible performance
      • Lean virtualisation-centric VMkernel delivers complete control over hardware resources
      • Supports dynamic allocation of computing resources
      • Highly available, fault-tolerant and secure design
      • Supports both scale-up and scale-out strategies
      Datacenter-Class Virtual Infrastructure for Mission-Critical Environments
    • Bare-Metal vs. Hosted Virtualisation
      • Bare Metal
      • Hosted
      Copyright © 2005 VMware, Inc. All rights reserved.
      • Device support is inherited from host operating system for maximum hardware compatibility
      • Virtualisation installs like an application rather than like an operating system
      • Can run alongside conventional applications
      • Maximum performance with lowest overhead using certified hardware
      • Highly efficient direct I/O pass-through architecture for network and disk
      • Highly secure micro-kernel virtualisation layer— only 100Ks of lines of code versus 10–25 million lines of host operating system code
      • Advanced features like VMotion available
      (ESX Server) (Workstation, ACE & GSX Server)
    • ESX Server Components Copyright © 2005 VMware, Inc. All rights reserved. VMkernel Shared SAN Storage VMware Management Interface (MUI) & Remote Console
      • VMkernel
        • Manages all virtual machines
      • Service console
        • Linux-based bootstrap manager and administrative interface
      • VMware management interface (MUI)
        • Access to ESX Server admin
      • ESX Server remote console
        • Access to virtual machines
      • VMware Scripting API
        • Automate management & monitoring
    • ESX Server Remote Management Features Copyright © 2005 VMware, Inc. All rights reserved.
      • Web-based management interface
        • Create, modify, stop, start, suspend/resume virtual machines
        • Monitor CPU and memory usage
        • Access from any browser
      • Remote console
        • Windows and Linux versions
        • Create, configure & manage VMs
        • Full mouse and keyboard support
        • Remote full screen
        • Tabbed “quick switch” interface
        • Good low-bandwidth performance
      • SSL security
    • ESX Server is a Resource Multiplier with Very Granular Resource Management Copyright © 2005 VMware, Inc. All rights reserved.
      • All physical resources are shared by virtual machines resulting in a multiplier effect
        • The goal is to maximise hardware utilisation for greatest ROI while providing isolation
      • ESX Server provides very granular resource allocation per virtual machine
        • Can establish minimum, maximum, and proportional share amounts per VM for CPU, memory, disk and network bandwidth and modify these allocations while they are running
        • Allows apps to use greater resources periodically without requiring a constant allocation
      Resource Physical Server Virtualisation CPU Memory Storage Network 4-Way Server 20–30 VMs 6GB Server 12GB VM Memory 2 HBAs (paired) 32 Virtual Disks 2 NICs (teamed) 16 Virtual NICs
    • VMware Virtual SMP
      • Add-on module for ESX Server
      • Allows single virtual machine to span two processors
      • Benefits
        • Increased virtual machine performance
        • Move more intensive workloads into virtual machines
        • Meet requirements of applications designed for 2-way systems
        • Develop and test applications in dual processor environments
      • Compatible with dual-core and hyperthreaded processors

    • Copyright © 2005 VMware, Inc. All rights reserved. Device Management for Hardware Virtualisation
      • VMkernel virtualises the physical hardware and presents each virtual machine with a standardised virtual device
      • This standardisation makes virtual machines uniform and portable across platforms
      1-4 Ports 1-4 Ports 1-2 Drives 1-4 Ethernet Adapters 1-4 SCSI Adapters 1-15 Devices Each Up to 2 CD-ROMs Up to 3.6GB RAM and 1 CPU or 2 CPUs with VMware Virtual SMP
    • Network Management for Network Virtualisation Copyright © 2005 VMware, Inc. All rights reserved.
      • VMs use virtual NICs mapped to one or more physical NICs through virtual switches
        • Each virtual NIC gets its own MAC address
        • Zero collisions occur for internal traffic
      • NIC Teaming groups 2-10 physical NICs to form a highly redundant network device
        • Statically load-balances traffic for all VMs
        • Traffic shaping can manage bandwidth per VM
        • Failover is offered transparently to all VMs
      • Extra Security available for virtual NICs
        • VMs on the same virtual switch cannot see each other’s traffic
        • Disallow MAC address changes by the OS
        • Disallow forged source MAC transmits
        • Disallow promiscuous mode
      Teamed Physical NICs
    • Access Management ESX Roles Allow Granular Management Control Copyright © 2005 VMware, Inc. All rights reserved.
      • ESX Server allows for four levels of privilege to control access to ESX Servers and their virtual machines
      • VirtualCenter extends the ESX Server access control by allowing staff to manage all ESX Servers from a central point with active directory domain integration
