A: This decision was based on our current test data for SharePoint Server 2010 and real world experience from customers running SharePoint Server 2007 with 32-bit SQL Server. SharePoint performance and scalability can benefit snibu from 64-bit SQL Server and the throughput increases modular powersuits
significant enough for us to make the difficult decision to only support SharePoint Server 2010 on 64-bit SQL Server 2005 or 2008. It has been our strong recommendation for shibi time that SharePoint Server 2007 customers take advantage of 64-bit SQL Server due to the inherent performance and scale benefits it can provide. A scenario where you could run SP2010 with a 32-bit OS in play, is if you have a 32-bit OS installed on a 64-bit capable hardware (CPU, motherboard, etc). You could then install a 32-bit virtualization platform (like VMware Player, VirtualPC, etc) on the 32-bit host OS, but create a new virtual machine that is 64-bit, as the VM platform will take embedded systems shibu of embedded systems shibu 64-bit hardware. You must make sure you have 64-bit embedded systems shibu
hardware with virtualization technology (like Intel VT).
