3. What is Virtual Infrastructure?
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
VMware technology provides a thin virtualization layer that
encapsulates operating systems and applications
into portable virtual machines

4. What is Virtualization?
Without Virtualization With Virtualization
Application
Operating System
Hardware
• VMware provides hardware virtualization 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
• Virtualization provides direct access to the hardware resources to give
you much greater performance than software emulation

6. Three Key Properties of Virtualization
Partitioning Isolation Encapsulation
• Run multiple operating • Isolate faults and security at • Encapsulate the entire state
systems on one physical the hardware level of the virtual machine in
machine • Dynamically control CPU, hardware-independent files
• Fully utilize server resources memory, disk and network • Save the virtual machine state
• Support high availability as resources per virtual as a snapshot in time
shared data is cluster-ready machine • Re-use or transfer whole virtual
for failover and redundancy • Guarantee service levels machines with a simple file copy

7. VMware ESX Server
Datacenter-Class • ESX Server is a virtual
Virtual Infrastructure machine platform with a
for Mission-Critical Environments bare-metal architecture for
highest possible performance
• Lean virtualization-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 Virtualization
Hosted (Workstation, ACE
& GSX Server) Bare Metal (ESX Server)
• Device support is inherited from host • Maximum performance with lowest overhead using
operating system for maximum hardware certified hardware
compatibility • Highly efficient direct I/O pass-through architecture
• Virtualization installs like an application for network and disk
rather than like an operating system • Highly secure micro-kernel virtualization layer—
• Can run alongside conventional only 100Ks of lines of code versus 10–25 million
applications lines of host operating system code
• Advanced features like VMotion available

9. ESX Server Components
• VMkernel
• Manages all virtual machines
• Service console
• Linux-based bootstrap manager
VMkernel and administrative interface
• VMware management
interface (MUI)
• Access to ESX Server admin
• ESX Server remote console
• Access to virtual machines
• VMware Scripting API

10. ESX Server Remote Management Features
• 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

11. ESX Server is a Resource Multiplier
with Very Granular Resource Management
Resource Physical Server Virtualization
CPU 4-Way Server 20–30 VMs
Memory 6GB Server 12GB VM Memory
Storage 2 HBAs (paired) 32 Virtual Disks
Network 2 NICs (teamed) 16 Virtual NICs
• All physical resources are shared by virtual machines resulting in a
multiplier effect
• The goal is to maximize hardware utilization 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

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 Virtualization
1-4 Ports 1-4 Ports
Up to 2
CD-ROMs 1-2 Drives
• VMkernel virtualizes
the physical hardware
and presents each
virtual machine with a
standardized virtual
device
• This standardization
makes virtual
machines uniform and
1-4 Ethernet Adapters
portable across
1-4 SCSI Adapters platforms
1-15 Devices Each
Up to 3.6GB RAM and 1 CPU
or 2 CPUs with VMware Virtual SMP
Copyright © 2005 VMware, Inc. All rights reserved.

14. Network Management
for Network Virtualization
• 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 Teamed Physical NICs
• Disallow forged source MAC transmits
• Disallow promiscuous mode

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
