Upgrade Advantages
The following is a list of advantages that customers have cited as their main reasons for upgrading to vCloud Director 5.1. However, not all new features are available upon completing Phase I.

User/t
enant u
sability Improvements – The user/tenant usability improvements in vCloud Director
5.1 are targeted at enabling enterprises and service providers to appeal to less tech-savvy vCloud
consumers, and expand to users who may not necessarily work in traditional infrastructure management roles.
Elastic virtual datacenter
– Customers can purchase a virtual datacenter
of arbitrary size from a robust set of offerings and grow it at will. vCloud Director and vSphere intelligently manage capacity below a robust virtual datacenter
abstraction and prevent
virtual datacenter
s from hitting
boundaries unless physical capacity is exhausted.
Multiple classes of capacity – vApps can be deployed as multitier
applications with differing infrastructure performance requirements across different tiers (for example,
DB on fast storage, web tier on standard storage) within a single application construct.
New features enabled by upgrade to vCloud Director 5.1:

vSphere Storage DRS.
Storage profiles.

Virtual hardware version 9.
Windows 8 guest OS support.
Snapshot and revert.
Multi-interface vCloud Networking and Security
Edge supports
ten interfaces that can
be configured as either uplinks (e
xternal n
etworks) or i
nternal i
nterfaces (facing i
nternal networks).
Fast p
rovisioning support for more than eight
hosts.
Support for Google Chrome browser.
This is not an exhaustive list. Completion of all four upgrade phases is required to enable all new features.
