3. Infrastructure is what
connects resources to your
business
Virtual infrastructure is a
dynamic mapping of your
resources to your business
Result: decreased costs
and increased efficiencies
and responsiveness
What is Virtual Infrastructure?
VMware technology provides a thin virtualisation layer that
encapsulates operating systems and applications
into portable virtual machines

What is 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

5. Three Key Properties of Virtualisation
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

7. • 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

8. Bare-Metal vs. Hosted Virtualisation
Bare MetalHosted
• 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)

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

10. • Web-based management
interface

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 Remote Management Features

11. ESX Server is a Resource Multiplier
with Very Granular Resource Management
• 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

4-Way Server 20–30 VMs
6GB Server 12GB VM Memory
2 HBAs (paired) 32 Virtual Disks
2 NICs (teamed) 16 Virtual NICs

12. 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

13. 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

14. Network Management
for Network Virtualisation
• 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

15. Access Management
ESX Roles Allow Granular Management Control
• 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
