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 thatencapsulates 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


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


• 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

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

Shared SAN Storage

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


• 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• Good low-bandwidth performance

• SSL security

ESX Server Remote Management Features


ESX Server is a Resource Multiplierwith 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

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


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 Adapters1-15 Devices Each

Up to 2 CD-ROMs

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


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


Access ManagementESX 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
