Newly installed vSphere 5.x hosts use VMFS5, an updated version of the

VMware File System for vSphere 5.x. Unlike earlier versions, ESXi 5.x does

not create VMFS partitions in second and successive disks.

Upgraded systems do not use GUID Partition Tables (GPT), but retain the

older MSDOS-based partition label.

VMware vCenter Server

Appliance

As an alternative to installing vCenter Server on a Windows machine,

vSphere 5.x provides the VMware vCenter Server Appliance. The vCenter

Server Appliance is a preconfigured Linux-based virtual machine optimized

for running vCenter Server and associated services.

vSphere Web Client

The vSphere Web Client is a server application that provides a browser-

based alternative to the deprecated vSphere Client. You can use a Web

browser to connect to the vSphere Web Client to manage an ESXi host

through a vCenter Server.

vCenter Single Sign-On

vSphere versions 5.1 and later include vCenter Single Sign-On as part of the

vCenter Server management infrastructure. This change affects vCenter

Server installation, upgrading, and operation. Authentication by vCenter

Single Sign-On makes the VMware cloud infrastructure platform more

secure by allowing the vSphere software components to communicate with

each other through a secure token exchange mechanism, instead of requiring

each component to authenticate a user separately with a directory service

like Active Directory. See “How vCenter Single Sign-On Affects vCenter

Server Upgrades,” on page 32

Differences Between vSphere Upgrades and Updates

vSphere products distinguish between upgrades, which make major changes to the software, and updates,

which make smaller changes to the software.

VMware product versions are numbered with two digits, for example, vSphere 5.1. A release that changes

either digit, for example, from 4.1 to 5.0, or from 5.0 to 5.1, involves major changes in the software, and

requires an upgrade from the previous version. A release that makes a smaller change, requiring only an

update, is indicated by an update number, for example, vSphere 5.1 Update 1.

When you upgrade an ESXi host, some host configuration information is preserved in the upgraded version,

and the upgraded host, after rebooting, can join a vCenter Server instance that has been upgraded to the

same level. Because updates and patches do not involve major changes to the software, host configuration is

not affected.
