Infrastructure is whatconnects resources to yourbusiness
Virtual infrastructureis adynamic mapping of yourresources to your business
Result: decreased costsand increased efficienciesand responsiveness
What is Virtual Infrastructure?
VMware technology provides a thin virtualisation layer thatencapsulates operating systems and applications
into portable virtual machines

What is Virtualisation?
VMware provides hardware virtualisation that presents a completex86 platform to the virtual machine
Allows multiple applications to run in isolation within virtual machineson the same physical machine
Virtualisation provides direct access to the hardware resources togive you much greater performance than software emulation

Three Key Properties of Virtualisation
Partitioning Run multiple operating
systems on one physical
machine
Fully utilise server resources
Support high availability asshared data is cluster-readyfor failover and redundancy
Encapsulation Encapsulate the entire state
of the virtual machine in
hardware-independent files
Save the virtual machine stateas a snapshot in time
Re-use or transfer whole virtualmachines with a simple file copy
Isolation Isolate faults and security at
the hardware level
Dynamically control CPU,memory, disk and networkresources per virtualmachine
Guarantee service levels

ESX Server is a virtualmachine platform with abare-metal architecture forhighest possible performance
Lean virtualisation-centric
VMkernel delivers completecontrol over hardwareresources
Supports dynamic allocationof computing resources
Highly available, fault-tolerantand secure design
Supports both scale-up andscale-out strategies

Bare-Metal vs. Hosted Virtualisation
Bare MetalHosted
Device support is inherited from hostoperating system for maximum hardwarecompatibility
Virtualisation installs like an applicationrather than like an operating system
Can run alongside conventionalapplications
Maximum performance with lowest overhead usingcertified hardware
Highly efficient direct I/O pass-through architecturefor network and disk
Highly secure micro-kernel virtualisation layeronly 100Ks of lines of code versus 1025 millionlines of host operating system code
Advanced features like VMotion available

ESX Server is a Resource Multiplierwith Very Granular Resource Management
All physical resources are shared by virtual machines resulting in amultiplier 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

VMware Virtual SMP
Add-on module for ESX Server
Allows single virtual machine tospan two processors
Benefits
Increased virtual machine performance
Move more intensive workloads intovirtual machines
Meet requirements of applicationsdesigned for 2-way systems
Develop and test applications in dual
processor environments Compatible with dual-core and
hyperthreaded processors

Network Managementfor Network Virtualisation
VMs use virtual NICs mapped to one ormore 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 toform 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 others traffic Disallow MAC address changes by the OS
Disallow forged source MAC transmits
Disallow promiscuous mode
Teamed Physical NICs

Access ManagementESX Roles Allow Granular Management Control
ESX Server allows for fourlevels of privilege to controlaccess to ESX Servers andtheir virtual machines
VirtualCenter extends theESX Server access controlby allowing staff to manageall ESX Servers from acentral point with active
directory domain integration
