Ok experts, whats the deal with Windows 2003 Sever Datacenter Edition. What are the big differences that I should know about before moving from the Enterprise Edition. Pros and Cons..
Watch Question

Overview here:


Differences in the versions is here:


Sys requirements:


For this, the main thing is it needs to be at least an 8-way proc box

Basically Datacenter edition is for serious high end applications that require lots of processing power.  it supports alot more processors and RAM.

This article can explain the benefits of it:


All that said, your "move" to Datacenter edition means going through an OEM (IBM, HP, etc.).  They are the only ones that can sell you Datacenter edition, and it has to come preinstalled on their hardware.  You buy the licensing from them.

Data Center is so specialized, I believe that you have to work with Microsoft directly to deploy this.  I believe that will replicate your environment to verify compatibility with your application and Microsoft datacenter.  You have to run Data Center on special hardware certified by MS.  I don't know of anyone using this...but this is what I have heard about the product.

Anyone using datacenter out there?

 How do I obtain Windows Server 2003 R2 Datacenter Edition?
A. Windows Server 2003 R2 Datacenter Edition is only available through qualified original equipment manufacturers (OEMs).
Q. How do I license Windows Server 2003 R2 Datacenter Edition?
A. The Server/Client Access Licensing (CAL) model applies to Windows Server 2003 R2 Datacenter Edition. However, the server license component differs for Datacenter Edition, in comparison to Standard or Enterprise Edition, in that the cost of the server license varies with the number of processors installed on the Datacenter server. For further detail, see Licensing Windows Server 2003 R2 Datacenter Edition.
Q. Do I need to acquire Windows CALs to access servers running Datacenter Edition?
A. Yes. If the Datacenter server is being accessed or used, a CAL is required for every user or device, unless the access is anonymous and gained through the Internet.


So I take it that this is why HP is pushing new stuff on us? REVENUE!

To the author:

I don't think HP really pushes DataCenter.  Very few companies run it overall.

You can't simply upgrade to it.  You have to purchase a purpose built server with it pre-installed, and these servers aren't cheap.

I remember my last company buying an HP/Compaq server with DataCenter on it, and the total costs for the server were around $300,000.

The idea is that you are buying something that will never go down...with redundant everything, and processing power like mad.
