Scalable Shared Databases

Updated: 5 December 2005

The scalable shared database feature, which is new in Microsoft SQL Server, allows you to scale out a read-only database built exclusively for reporting purposes (a reporting database). The reporting database must reside on a set of dedicated, read-only volumes whose primary purpose is hosting the database. Using commodity hardware for servers and volumes, you can scale out a reporting database that provides an identical view of the reporting data on multiple reporting servers. This feature also permits a smooth update path for the reporting database.
