VMware Mission
Transform industry standard server and desktop computing through virtualisation
Copyright © 2005 VMware, Inc. All rights reserved.

What is Virtual Infrastructure? Copyright © 2005 VMware, Inc. All rights reserved. Infrastructure is what connects resources to your business Virtual infrastructure is a dynamic mapping of your resources to your business Result: d ecreased costs and increased efficiencies and responsiveness VMware technology provides a thin virtualisation layer that encapsulates operating systems and applications into portable virtual machines

What is Virtualisation? Copyright © 2005 VMware, Inc. All rights reserved. Hardware Application Operating System With Virtualisation Without 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 Copyright © 2005 VMware, Inc. All rights reserved.
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

VMware ESX Server Copyright © 2005 VMware, Inc. All rights reserved.
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
Datacenter-Class Virtual Infrastructure for Mission-Critical Environments

Bare-Metal vs. Hosted Virtualisation
Bare Metal
Hosted
Copyright © 2005 VMware, Inc. All rights reserved.
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)

Good low-bandwidth performance
SSL security

ESX Server is a Resource Multiplier with Very Granular Resource Management Copyright © 2005 VMware, Inc. All rights reserved.
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
Resource Physical Server Virtualisation CPU Memory Storage Network 4-Way Server 20–30 VMs 6GB Server 12GB VM Memory 2 HBAs (paired) 32 Virtual Disks 2 NICs (teamed) 16 Virtual NICs

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

Copyright © 2005 VMware, Inc. All rights reserved. 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

Network Management for Network Virtualisation Copyright © 2005 VMware, Inc. All rights reserved.
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 Management ESX Roles Allow Granular Management Control Copyright © 2005 VMware, Inc. All rights reserved.
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
