VMware ESX Server provides a bare-metal virtualization platform for running multiple virtual machines on a single physical server. It allows for high utilization of server resources and isolation of virtual machines. ESX Server provides tools for granular management of CPU, memory, storage and network resources for virtual machines. It also includes features for remote management, availability, live migration of virtual machines, and support for many operating systems and hardware configurations.

VMware Mission Transform industry standard server and desktop computing through virtualisation Copyright © 2005 VMware, Inc. All rights reserved. Application OS Hardware Virtualisation Hardware App OS App OS 70% Reduction in Operating Costs 40% Reduction in Hardware and Software Costs Increased Reliability & Responsiveness Greatly Enhanced Business Continuity Increased Utilisation & Return on Assets Application OS Hardware
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)
ESX Server Components Copyright © 2005 VMware, Inc. All rights reserved. VMkernel 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
ESX Server Remote Management Features Copyright © 2005 VMware, Inc. All rights reserved. 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 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.
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
