- Virtualization lets you run multiple virtual machines on a single physical machine, with each virtual machine sharing the resources of that one physical computer across multiple environments.
- Different virtual machines can run different operating systems and multiple applications on the same physical computer.
- VMware virtualization works by inserting a thin layer of software directly on the computer hardware or on a host operating system.
- Safely run several operating systems and applications at the same time on a single computer, with each having access to the resources it needs when it needs them.
VMware vSphere
VMware vSphere, the industry-leading virtualization platform for building cloud infrastructures, enables you to run business critical applications with confidence and respond to the business faster. vSphere accelerates the shift to cloud computing for existing datacenters and underpins compatible public cloud o"erings, forming the foundation for the industry's only hybrid cloud model.
VMware vSphere 5.0 has finally arrived and includes several new unique features - such as Storage DRS and Autodeploy - that deliver unprecedented value to VMware customers. Unlike prior versions, vSphere 5 supports only the ESXi hypervisor architecture, the only thin purpose-built hypervisor that does not depend on a general purpose operating system.
ESXi and ESX Architectures Compared
VMware ESXi is VMware’s most advanced hypervisor architecture. Learn about the differences with the previous generation architecture, VMware ESX:
| Capability | ESX 4.1 | ESXi 4.1 | ESXi 5.0 |
|---|---|---|---|
| Service Console | Present | Removed | Removed |
| Admin/config CLIs | COS + vCLI | PowerCLI + vCLI | PowerCLI + vCLI (enhanced) |
| Advanced Troubleshooting | COS | Tech Support Mode | ESXi Shell |
| Scripted Installation | Supported | Supported | Supported |
| Boot from SAN | Supported | Supported | Supported |
| SNMP | Supported | Supported (limited) | Supported |
| Active Directory | Integrated | Integrated | Integrated |
| HW Monitoring | 3rd party agents in COS | CIM providers | CIM providers |
| Serial Port Connectivity | Supported | Not Supported | Supported |
| Jumbo Frames | Supported | Supported | Supported |
| Rapid deployment and central management of hosts via Auto Deploy | Not Supported | Not Supported | Supported |
| Custom image creation and management | Not Supported | Not Supported | Supported |
| Secure syslog | Not Supported | Not Supported | Supported |
