2
Virtualisation technologies

• Virtual Networks
• Virtual Storage as provided by a SAN
• Virtual Desktops
• Grid Computing
• Java Virtual Machines
• Virtual Machines

3
What is a Virtual Machine?

• A virtual machine, loosely defined, is a
  framework or methodology of dividing the physical
  resources of a single computer into multiple
  execution environments

4
Enterprise Virtual Machine solutions

• VM on mainframe
• Clustering technologies (virtual host)
• Egenera BladeFrame
• Sun Microsystems Domains and Zoning
• MS Virtual PC, Virtual Server
• Intel Virtualisation Technology (Vanderpool)
• Xen Virtual Machine Monitor
• VMware workstation, GSX, ESX

5
VM on Mainframe

• Virtual Machines are not new
• Late 1990s companies finding new uses for their
  Mainframes via Virtual Machines.
• Linux now widely run on Mainframes in Virtual
  Machines

6
Clustering technologies

• Load balancing
• Oracle 9i RAC
• Microsoft SQL Server 2000
• Microsoft Cluster
• Sun Cluster
• Veritas Cluster

7
Egenera BladeFramehttp//www.egenera.com

• Egenera Incorporated March 2000, first BladeFrame
  release in April 2001
• Unique Processing Area Network (PAN) architecture
• Provides up to 24 two-way and/or four-way Intel
  SMP processing resources (Egenera Processing
  Blade)
• Redundant central controllers (Egenera Control
  Blade)
• Redundant integrated switches (Egenera Switch
  Blade)
• Redundant, high speed, low latency interconnets
  (Egenera BladePlane)

8
Egenera BladeFrame

• Processing Blades have no personality
• Control Blades run Linux with virtualisation
  software (Pan Manager)
• As few as eight cables required to connect
  redundantly to SAN storage and the IP network
• A virtual machine is allocated to a processing
  blade

Egenera BladeFrame
BladePlane 2.5 Gigabits/sec over a switched
fabric interconnect Provides Processing blade
I/O, network communication and power distribution
10
Sun Microsystems

• WABI and SunPC allowed Microsoft applications to
  run on Solaris
• Solaris Domains have been available for some time
  on high end servers.
• A single physical system can run multiple Solaris
  instances
• /kernel is shared between zones, all else is
  independent

11
Solaris Containers

• New feature of Solaris 10
• Based on same concepts as FreeBSD Jails
• Up to 8191 virtual views of the same run time
  environment can be created.
• Applications can be partitioned from each other
  on the same system but still have the same
  underlying operating system

12
MS Virtual PC 2004, Virtual Server 2005

• Microsoft has included virtualization as a key
  component of its server offerings for the
  Enterprise with the acquisition of Connectix in
  early 2003
• All Microsoft virtual machine products require a
  Microsoft host operating system
• Only supports Microsoft operating systems as
  guests
• Virtual Server standard edition supports up to 4
  processors on the host
• Virtual Server Enterprise Edition supports up to
  32 processors
• Physical to Virtual tool in development

13
Intel Virtualisation Technology

• Vanderpool Technology (VT) is a set of hardware
  enhancements to Intel server and client platforms
  that can improve virtualisation solutions.
• VT will provide a foundation for widely-deployed
  virtualisation solutions
• Provides headroom for more robust hardware
  assisted virtualisation solutions
• Intel platforms supporting VT will ship in 2005
  for desktop and Intel Itanium Processor based
  servers- 2006 for mobile platforms and Intel
  Xeon processor based servers and workstations

14
Xen Virtual Machine Monitor

• Xen is a virtual machine monitor (VMM) for
  x86-compatible computers. Xen can securely
  execute multiple virtual machines, each running
  its own OS, on a single physical system with
  close-to-native performance.
• Xen currently only runs on Linux host systems
• Guest operating systems currently require porting
• To be incorporated into Linux 2.6 kernel

15
VMware

• Producing Intel based virtual machine technology
  since 1998
• Workstation and GSX products require a host
  operating system
• Released ESX Server product runs on the bare
  metal
• Virtual SMP module
• P2V (Physical to Virtual) utility and Platespin
  PowerP2V
• VirtualCentre allows centralised management of
  servers and Virtual Machines
• VMware ACE provides secure, standardized PC
  desktop environments

16
x86 Architecture with VMware
17
VMware Virtual Machine Technology

• Allows each Virtual Machine (VM) to be managed as
  a unit
• Presents a virtual view of hardware to each VM
• Manages access to physical hardware
• Allows sharing of resources
• Ensures isolation of each VM
• Is not emulation

18
Key Benefits of a Virtual Machine

• Compatibility
• Guest OS sees a standard Intel x86-based PC
• Isolation
• A VMs state is unaffected by the state of other
  VMs
• Totally separate OS, registry, applications and
  data files
• Encapsulation
• State of a VM can be captured
• Files representing a VM are portable
• Hardware-independence
• Virtual hardware can be configured identically
  regardless of underlying physical hardware

19
Comparing the Server Products
VMware GSX Server
VMware ESX Server

• Hosted on Windows or Linux
• Maximum hardware compatibility
• Up to 64 VMs per GSX Server
• Lower price point
• Up to 3.6GB RAM per VM
• Supports VirtualCenter

• Runs natively
• Maximum scalability and performance
• Up to 80 VMs per ESX Server
• SMP support
• Advanced memory management
• Dynamic resource allocation
• Up to 3.6GB RAM per VM
• Supports VirtualCenter

20
Main reasons for distributed systems
virtualisation

• Disaster recovery solution
• Consolidate workloads of under-utilised systems
• Support the need to run legacy applications
• Maintain SLAs by guaranteeing resources
• Moving from a test or development environment to
  production becomes an easy task
• Increased ROI on hardware

21
Main Considerations when virtualising

• Licensing for operating systems and applications
• System profiling important if using for
  consolidation
• Is virtualisation suitable?
• Configuration management policy
• Networking infrastructure for Virtual machines is
  also virtualised
• Support for the operating systems running within
  the virtual machines
