The vCenter Server autorun.exe application includes links to install the following optional components:
vSphere Client Client application used to connect to an ESXi or legacy ESX host directly, or indirectly through a vCenter Server.
vSphere Web Client Server application that provides a browser-based alternative to the vSphere Client. You can use the vSphere Web Client to manage an ESXi host by Web browser through a vCenter Server.
vSphere Update Manager vCenter Server component that provides security monitoring and patching support for hosts and virtual machines.
vSphere ESXi Dump Collector vCenter Server support tool. You can configure ESXi to dump the vmkernel memory to a network server, rather than to a disk, when the system has encountered a critical failure. The Dump Collector ollects such memory dumps over the network.
vSphere Syslog Collector vCenter Server support tool that provides a unified architecture for system logging and enables network logging and combining of logs from multiple hosts.
vSphere Auto Deploy vCenter Server support tool that provisions and customizes physical hosts by loading the ESXi image directly into memory. Using Auto Deploy you can provision and reprovision hundreds of ESXi hosts very efficiently with vCenter Server.
vSphere Authentication Proxy vCenter Server support tool that enables ESXi hosts to join a domain without using Active Directory credentials. This tool enhances security for PXE-booted hosts and hosts that are provisioned using Auto Deploy, by removing the need to store Active Directory credentials in the host configuration.
