Pages and Extents Architecture Guide

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 guide describes the data structures that are used to manage pages and extents in all versions of SQL Server. Understanding the architecture of pages and extents is important for designing and developing databases that perform efficiently.

Pages and Extents

The fundamental unit of data storage in SQL Server is the page. The disk space allocated to a data file (.mdf or .ndf) in a database is logically divided into pages numbered contiguously from 0 to n. Disk I/O operations are performed at the page level. That is, SQL Server reads or writes whole data pages.

Extents are a collection of eight physically contiguous pages and are used to efficiently manage the pages. All pages are organized into extents.


Take a regular book: all content in it is written on pages. Similar to a book, in SQL Server all the data rows are written on pages. In a book, all pages are the same physical size. Similarly, in SQL Server all data pages are the same size – 8 kilobytes. In a book most pages contain the data – the main content of the book – and some pages contain metadata about the content – for example table of contents and index. Again, SQL Server is not different: most pages contain actual rows of data which were stored by users; these are called Data pages and text/image pages (for special cases). The Index pages contain index references about where the data is and finally there are system pages that store variety of metadata about the organization of the data (PFS, GAM, SGAM, IAM, DCM, BCM pages). See table below for page types and their description.

As mentioned, in SQL Server, the page size is 8-KB. This means SQL Server databases have 128 pages per megabyte. Each page begins with a 96-byte header that is used to store system information about the page. This information includes the page number, page type, the amount of free space on the page, and the allocation unit ID of the object that owns the page.

The following table shows the page types used in the data files of a SQL Server database.

Page type Contents
Data Data rows with all data, except text, ntext, image, nvarchar(max), varchar(max), varbinary(max), and xml data, when text in row is set to ON.
Index Index entries.
Text/Image Large object data types: (text, ntext, image, nvarchar(max), varchar(max), varbinary(max), and xml data)
Variable length columns when the data row exceeds 8 KB: (varchar, nvarchar, varbinary, and sql_variant)
Global Allocation Map, Shared Global Allocation Map Information about whether extents are allocated.
Page Free Space (PFS) Information about page allocation and free space available on pages.
Index Allocation Map Information about extents used by a table or index per allocation unit.
Bulk Changed Map Information about extents modified by bulk operations since the last BACKUP LOG statement per allocation unit.
Differential Changed Map Information about extents that have changed since the last BACKUP DATABASE statement per allocation unit.


Log files do not contain pages; they contain a series of log records.

Data rows are put on the page serially, starting immediately after the header. A row offset table starts at the end of the page, and each row offset table contains one entry for each row on the page. Each row offset entry records how far the first byte of the row is from the start of the page. Thus, the function of the row offset table is to help SQL Server locate rows on a page very quickly. The entries in the row offset table are in reverse sequence from the sequence of the rows on the page.


Large Row Support

Rows cannot span pages, however portions of the row may be moved off the row’s page so that the row can actually be very large. The maximum amount of data and overhead that is contained in a single row on a page is 8,060 bytes (8-KB). However, this does not include the data stored in the Text/Image page type.

This restriction is relaxed for tables that contain varchar, nvarchar, varbinary, or sql_variant columns. When the total row size of all fixed and variable columns in a table exceeds the 8,060-byte limitation, SQL Server dynamically moves one or more variable length columns to pages in the ROW_OVERFLOW_DATA allocation unit, starting with the column with the largest width.

This is done whenever an insert or update operation increases the total size of the row beyond the 8,060-byte limit. When a column is moved to a page in the ROW_OVERFLOW_DATA allocation unit, a 24-byte pointer on the original page in the IN_ROW_DATA allocation unit is maintained. If a subsequent operation reduces the row size, SQL Server dynamically moves the columns back to the original data page.

Row-Overflow Considerations

As mentioned earlier, a row cannot reside on multiple pages and can overflow if the combined size of variable-length data-type fields exceeds the 8060-byte limit. To illustrate, a table may be created with two columns: one varchar(7000) and another varchar (2000). Individually neither column exceeds the 8060-byte, but combined they could do so, if the entire width of each column is filled. SQL Server may dynamically move the varchar(7000) variable length column to pages in the ROW_OVERFLOW_DATA allocation unit. When you combine varchar, nvarchar, varbinary, sql_variant, or CLR user-defined type columns that exceed 8,060 bytes per row, consider the following:

  • Moving large records to another page occurs dynamically as records are lengthened based on update operations. Update operations that shorten records may cause records to be moved back to the original page in the IN_ROW_DATA allocation unit. Querying and performing other select operations, such as sorts or joins on large records that contain row-overflow data slows processing time, because these records are processed synchronously instead of asynchronously.
    Therefore, when you design a table with multiple varchar, nvarchar, varbinary, sql_variant, or CLR user-defined type columns, consider the percentage of rows that are likely to flow over and the frequency with which this overflow data is likely to be queried. If there are likely to be frequent queries on many rows of row-overflow data, consider normalizing the table so that some columns are moved to another table. This can then be queried in an asynchronous JOIN operation.
  • The length of individual columns must still fall within the limit of 8,000 bytes for varchar, nvarchar, varbinary, sql_variant, and CLR user-defined type columns. Only their combined lengths can exceed the 8,060-byte row limit of a table.
  • The sum of other data type columns, including char and nchar data, must fall within the 8,060-byte row limit. Large object data is also exempt from the 8,060-byte row limit.
  • The index key of a clustered index cannot contain varchar columns that have existing data in the ROW_OVERFLOW_DATA allocation unit. If a clustered index is created on a varchar column and the existing data is in the IN_ROW_DATA allocation unit, subsequent insert or update actions on the column that would push the data off-row will fail. For more information about allocation units, see Table and Index Organization.
  • You can include columns that contain row-overflow data as key or nonkey columns of a nonclustered index.
  • The record-size limit for tables that use sparse columns is 8,018 bytes. When the converted data plus existing record data exceeds 8,018 bytes, MSSQLSERVER ERROR 576 is returned. When columns are converted between sparse and nonsparse types, Database Engine keeps a copy of the current record data. This temporarily doubles the storage that is required for the record.
  • To obtain information about tables or indexes that might contain row-overflow data, use the sys.dm_db_index_physical_stats dynamic management function.


Extents are the basic unit in which space is managed. An extent is eight physically contiguous pages, or 64 KB. This means SQL Server databases have 16 extents per megabyte.

SQL Server has two types of extents:

  • Uniform extents are owned by a single object; all eight pages in the extent can only be used by the owning object.
  • Mixed extents are shared by up to eight objects. Each of the eight pages in the extent can be owned by a different object.

Up to, and including, SQL Server 2014 (12.x), SQL Server does not allocate whole extents to tables with small amounts of data. A new table or index generally allocates pages from mixed extents. When the table or index grows to the point that it has eight pages, it then switches to use uniform extents for subsequent allocations. If you create an index on an existing table that has enough rows to generate eight pages in the index, all allocations to the index are in uniform extents. However, starting with SQL Server 2016 (13.x), the default for all allocations in the database is uniform extents.



Up to, and including, SQL Server 2014 (12.x), trace flag 1118 can be used to change the default allocation to always use uniform extents. For more information about this trace flag, see DBCC TRACEON – Trace Flags.

Starting with SQL Server 2016 (13.x), the functionality provided by TF 1118 is automatically enabled for TempDB. For user databases, this behavior is controlled by the SET MIXED_PAGE_ALLOCATION option of ALTER DATABASE, with the default value set to OFF, and trace flag 1118 has no effect. For more information, see ALTER DATABASE SET Options (Transact-SQL).

Managing Extent Allocations and Free Space

The SQL Server data structures that manage extent allocations and track free space have a relatively simple structure. This has the following benefits:

  • The free space information is densely packed, so relatively few pages contain this information.
    This increases speed by reducing the amount of disk reads that are required to retrieve allocation information. This also increases the chance that the allocation pages will remain in memory and not require more reads.
  • Most of the allocation information is not chained together. This simplifies the maintenance of the allocation information.
    Each page allocation or deallocation can be performed quickly. This decreases the contention between concurrent tasks having to allocate or deallocate pages.
