7. blog.eardley.org.uk SharePoint – How does it use SQL? Most Service Applications utilise at least one database Service Applications At least one database per Web Application Each site collection can have a database Content Databases Multiple Databases My Sites Databases should not exceed 200GB in size With the exception of Records Centre databases

8. blog.eardley.org.uk Planning – How many databases does it need? Types of Database –Administration –Content –Service Applications How many databases will be required? How large do they need to be? How fast will they grow?

Because of this requirement, it is usually best not to have the Administration and Crawl databases located on the same server.Medium10GB The factors that influence growth include the number of best bets, the number of content sources and crawl rules, the security descriptions for the corpus, and how much traffic.50/50Mostly Up Search_Service_Application_Analy ticsReportingStoreDB_ None Medium to Large Write-intensive during analytics update90/10 Scale out by creating additional Analytics Reporting database using a split operation when the main database becomes >200 GB.

Search_Service_Application_LinkS toreDB_ We recommend that if you have sites that have heavy traffic, the Link database should use separate spindles from other databases Medium to Large The Link database grows on disk by 1 GB per 1 million documents fed. The click through data grows linearly with query traffic, 1 GB per million queries.30/70 Scale out by creating additional Link database per every 60 million documents crawled. Also add additional Link database per 100 million expected queries per year.
