Scaling out SQL Server 2005 article
2006/05/05This article appeared just recently on MSDN:
Scaling Out SQL Server 2005
It's a relatively high level document which covers how to think about
the data before going with a scale out solution, what factors impact a
scale out solution (such as how often the data is updated), and what
the main options are.
