VMware ESX Server offers a datacenter-class virtual infrastructure designed for mission-critical environments, providing substantial cost reductions (40% in hardware/software costs and 70% in operational costs) and enhanced reliability. The technology utilizes a thin virtualization layer that allows multiple operating systems and applications to run efficiently on shared hardware, improving resource utilization and business continuity. Key features include granular resource management, support for various guest operating systems, and advanced capabilities like VMotion for dynamic resource allocation.

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

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)

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

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
