The next release of Microsoft SharePoint will leave 32-bitness behind. Microsoft dropped the news that SharePoint 2010 will be 64-bit only in its blog and at a TechEd 2009 session. The new SharePoint will also require 64-bit Windows Server 2008 R2 and 64-bit SQL Server 2008 or 64-bit SQL Server 2005.
The Community Technology Preview of Office 2010 promised for July will not include SharePoint 2010, Tom Rizzo told TechEd attendees that the CTP will focus on the client applications.
In his day one keynote, Windows Server general manager Iain McDonald outlined the 64-bit-only future for Windows Server as well:
“I saw someone tweeted yesterday on Twitter, that they were surprised that Windows Server 2008 R2 is 64-bit only. It is 64-bit only. Get over it. You couldn’t buy a 32-bit system for a long while. That’s where we’re going, that’s where we’re investing.”
When Microsoft made the 64-bit leap with Exchange Server a few years back, there was considerable pushback. We’ll see if that holds true again.
