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


5/19


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 Remote Management Features


11/19


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

Device Managementfor Hardware Virtualisation

VMkernel virtualisesthe physical hardwareand presents eachvirtual machine with a

standardised virtualdevice

This standardisationmakes virtualmachines uniform andportable acrossplatforms

1-4 Ports 1-4 Ports

1-2 Drives

1-4 Ethernet Adapters

1-4 SCSI Adapters1-15 Devices Each

Up to 2CD-ROMs

Up to 3.6GB RAM and 1 CPUor 2 CPUs with VMware Virtual SMP


14/19


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
