Windows Server 2008 Editions
Windows Server 2008 Editions
The purpose of this page is to help you choose the best version of Microsoft Windows
Server 2008 for your circumstances.
Quick Question: Which version should I buy? Quick Answer: Windows Server 2008 Enterprise edition
(64bit).
My point is that if you are unsure, make the Windows Server 2008 Enterprise
edition your default choice. Another way to make sense of Microsoft's many
versions is to start with the Enterprise version, assess what it has to offer; then use that
knowledge as a
baseline to evaluate the other versions.
Note: for the purpose of this article,
I will use the terms 'edition' and 'version' interchangeably.
Microsoft's Windows Server 2008 Versions
Windows Server 2008 Standard
Windows Server 2008 Enterprise Edition (Recommended)
Windows Server 2008 Datacenter
Other considerations before you order a Windows Server 2008 edition are,
firstly, do you want a 32bit version, or do you have 64bit hardware waiting to install
your server? Secondly, would like to try the new Hyper-V technology?
Alternatively, do
you need to save money and buy a version without Hyper-V.
One new feature shared by Server 2008 and Vista is that Microsoft supply just one
DVD for all 64bit editions; consequently it's the Product Key that determines
which edition you install.
There is sister DVD for all 32bit versions. Incidentally, Windows
Server 2008 is the last Microsoft Operating system to have a 32bit version.
Three Specialist Editions of Server 2008
Web - Very restricted, dedicated for one specialist role
HPC (High Performance Computing) - For clustering
Itanium-based. These CPUs execute more instructions per clock cycle than x64 processors.
Two minor points, Core Server
is not available as installation option for Itanium-based systems. Also
there is no storage manager for SANs.
Windows Server Catalog (Hardware Compatibility List)
Two minutes of checking your hardware against the WSC (Windows Server Catalog), will save you a lifetime of grief dealing
with incompatibilities. Because server hardware is relatively cheap, if
you are installing Server 2008 on a production server,
don't coble something together. It's just not worth risking nearly-incompatible kit, sooner or later the mismatched
component will come back and bite you.
The best answer is treat yourself to new kit which is plastered
with the Logo - 'Certified for Windows Server 2008 hardware'. Don't accept
imitations, even at knock down prices.
Worth a look: check out the free Microsoft
Assessment and Planning Solution Accelerator. What this utility does
is assess your present hardware, then produces an Excel report on the fitness of
your machines to run Windows Server 2008.

Guy's Quick
Edition Check List
Nobody gets the sack for ordering the Enterprise Edition. If you try
and save money by purchasing the Standard Edition, you only need to slip-up on
one of the many 'banana skins' to nullify your savings. For example, with the Standard
Version you cannot deploy Hyper-V* or Terminal Services* in a big way. You
cannot install the Enterprise Edition of Exchange, neither can you create a cluster server.
My other rational for recommending Enterprise Edition is that compared with
the Standard Edition, it makes you future-proof. In two years you're going
to want to do extra 'stuff', if you install the Standard Edition you could be
constrained.
If you are considering the Datacenter, HPC, or Itanium-based Editions, they
you are going to need professional advice, thus contact a recognised Microsoft
partner and quiz their salesmen.
* You can install Hyper-V and Terminal Service on the Standard Edition, but
their restrictions will hurt all but the smallest organizations.
Licensing Your Windows Server 2008 Edition
You can bet that with Microsoft's Windows Server licensing, the past will not
equal the future. Each successive version of the Server (NT -> W2K -> W2K3
-> Server 2008) brings new licensing rules.
The biggest shock for newcomers is that in addition to spending $1,000 on a
server license, they are going to need Client Access Licenses (CALs). No ordinary mortal understands the
rules of one-time licenses, Enterprise Agreements (EAs) and Software Assurance
(SA).
If you need to grapple with Microsoft's Licensing then
speak with an expert. It's best to phone your local Microsoft Support line
and listen for the Licensing option. Servers are more complex to licence than Vista or XP, because you
also need to check the configuration, for example, per user, per device or per
server.
Then there is Terminal Server, and its licensing rules, I say again, phone
Microsoft and least ask them to explain their rules for your configuration.
To end with a piece of good news, Microsoft are going to 'liberalise' their
licensing for Windows Server 2008 Web edition. I think means that licenses
will be cheaper than for W2K3 Web server. Microsoft's rational is to take
some of the Apache web servers' market share.
Summary of Windows Server 2008 Editions
Before you purchase a Windows Server 2008 product key, review the various
options. One mistake to avoid is buying a 32bit DVD when you have
64bit hardware. If you are in doubt install the Enterprise edition or
version. Unfortunately, choosing the edition is only the start, you also
need to research the best licensing option for your users.
Train Signal has just released their
New Windows Server 2008 Training Course. As an MCT
trainer, I am a huge advocate of Train Signals products. What impresses is me is that they demonstrate everything that they teach and they stay away from traditional 'lecture-style' training. If
you are looking for a complete DETAILED coverage of Windows Server 2008, then I highly recommend that you give this course a try. I have reviewed their
6 hours plus of videos myself, and I guarantee that you will
not be disappointed!
