Install Windows Server 2003 Standard x64 or Server 2003 Enterprise x86?
Posted on 2008-10-29
Hello - We will be installing a new server in our office for a new line of business application we have purchased. We will be installing MS SQL Server 2005 Standard for this application to use as well. This will be a pretty resource demanding application. The server we have purchased is a Dell PowerEdge 2950 with Dual Quad-Core E5405 Xeon's (2.0GHz, 2x6MB Cache) and has 8GB of RAM and SAD RAID-5.
Since Windows Server 2003 Standard x86 (32-bit) does not support more than 4GB of RAM, we have to go with an O/S that does. This is merely a question of budget. I have an unused copy of Windows Server 2003 Enterprise Edition x86 and an unused copy of Windows Server 2003 Standard Edition x64. Given the demanding hardware requirements of the application, and the fact it runs on MS SQL Server 2005, which version of Windows do you think we would achieve the best performance with? I think that Enterprise x86 has to use PAE to address the memory beyond 4GB, but from what I understand an x64 version does not. I am not sure if that makes a difference or not. I also have read that Enterprise does better with multiple processors and has other features that I don't need like clustering and hot-add RAM. The application is not yet certified for Windows Server 2008 so the choices are 2003 Standard x64 or 2003 Enterprise x86. Thoughts anyone? Thanks in advance!
