The SQL Server Internals Viewer is an open source tool that provides insight into how SQL Server stores and organizes data physically. It integrates as an add-in with SQL Server Management Studio to display details like the physical layout of tables and indexes, transaction log contents, and different page types like data, index, and allocation pages. The tool can be downloaded from its Codeplex site and allows users to view how SQL Server handles storage tasks under the hood.
