Provide additional capabilities and features to vCenter Server. Generally,
additional modules (sometimes called plug-ins) are released separately, install
on top of vCenter Server, and can be upgraded independently. You can install
additional modules on the same computer as the vCenter Server system or on
a separate one. After the additional module is installed, you can activate the
module's client component, which enhances the vSphere Client with user
interface (UI) options. Additional modules include vCenter Update Manager,
vCenter Converter, and vCenter Guided Consolidation Service.
Installs on a Windows machine and is the primary method of interaction with
VMware vSphere. The vSphere Client acts as a console to operate virtual
machines and as an administration interface into the vCenter Server systems
and ESX hosts.
The vSphere Client is downloadable from the vCenter Server system and ESX
hosts. The vSphere Client includes documentation for administrators and
console users.
A browser-based interface for system administrators who need to access virtual
machines remotely or without a vSphere Client. vSphere Web Access is also
for people who use virtual machines as remote desktops.
Organize all the configuration data for the VMware vSphere environment. For
small deployments, the bundled Microsoft SQL Server 2005 Express database
lets you set up to 5 hosts and 50 virtual machines. vCenter Server supports
other database products for larger deployments. vCenter Update Manager also
requires a database. VMware recommends that you use separate databases for
vCenter Server and vCenter Update Manager.
