I’ve been working on a talk that I’ll be giving to the Dallas next month to the Dallas/Fort Worth User’s group (more on that in another post) and I ran across confirmation of something I’ve been telling students for over a year now. When you are buying new hardware for a SharePoint installation, you should ALWAYS buy 64-bit hardware. Yes, I know mixing and matching 64 and 32 bit servers in a SharePoint role isn’t recommended, but you should still try to make all new purchases 64-bit. Why? Because SharePoint makes extensive use of RAM for almost everything it does. The minimum SharePoint server I recommend anymore has 4GB RAM in it, and that’s the maximum for 32-bit hardware. But more importantly take a look at the following quote from the White Paper that Microsoft recommends everyone read BEFORE installing either SharePoint SP1 package.
“Windows SharePoint Services 3.0 and Office SharePoint Server 2007 are the last SharePoint Products and Technologies versions able to run on 32-bit hardware and operating systems.”
It’s now official. The next version of SharePoint will be 64-bit only. We’ve already seen this happen to Exchange and many have been predicting it would happen to SharePoint soon, but this is the first time I’ve seen it in print from an official Microsoft source.
