    That'll require half an article to explain from start to finish. Any specifics you want clearing up?

    As Gail indicated, that's a pretty large topic to cover without more details about what it is you're after. In my humble opinion, Kimberly Tripp is the reigning expert at explaining how page splits work and how they can impact performance. Do an internet search on her name, SQLSkills, Paul Randal and page splits and you'll come up with a lot of good information.

    They also put together a series of MCM videos that you can access here: http://www.sqlskills.com/sql-server-resources/sql-server-mcm-training-videos/. It's pretty advanced stuff but should give you an idea of what page splits are and how they can lead to index fragmentation and performance problems. Specifically, look at the ones on internals and indexes.

    And if you can afford it, Pluralsight has many more great training videos and no DBA or DB Developer should be without a copy of the SQL Server internals book that Kalen Delaney puts out.

    http://technet.microsoft.com/en-us/sqlserver/gg508878.aspx

    I don't offhand know of any articles specifically on page splits and I'm sure you can google as well as I can.
