From msdn:

The page is the fundamental unit of data storage in SQL Server. An extent is a collection of eight physically contiguous pages. Extents help efficiently manage pages.

This section describes the data structures that are used to manage pages and extents. Understanding the architecture of pages and extents is important for designing and developing databases that perform efficiently.

So what commands/utilities are available to visualize the data pages on SQL Server ?

DBCC PAGE

Paul Randal also has lots of stuff about on-disk structures and articles "Anatomy of a (insert storage thing here)" (some overlap here of course)
