Chapter 1 Installing Windows
System partition size <Windows Server 2008 64-bit Edition>
The system partition size can be calculated by using the following formula.
Size required to install the OS + paging file size + dump file size + application size
Full installations
Size required to install the OS = 16,720 MB
(Windows Server 2008 + Service Pack 2 DVD-ROM)
= 12,300 MB
(Windows Server 2008 with Service Pack 2)
= 11,600 MB
(Windows Server 2008)
Paging file size (recommended) = installed memory size × 1.5
Dump file size = installed memory size + 300MB
Application size = as required by the application
Server Core installations
Size required to install the OS = 9,300 MB
(Windows Server 2008 + Service Pack 2 DVD-ROM)
= 12,300 MB
(Windows Server 2008 with Service Pack 2)
= 4,100 MB
(Windows Server 2008)
Paging file size (recommended) = installed memory size × 1.5
Dump file size = installed memory size + 300MB
Application size = as required by the application
For example, if the installed memory size is 1 GB (1,024 MB) and Full installations is selected, the
partition size is calculated as follows:
11,600 MB + (1,024MB × 1.5) + 1,024MB+ 300MB+ application size
= 14,460MB + application size
The above mentioned partition size is the minimum partition size required for system installation.
Ensure that the partition size is sufficient for system operations.
If the partition size for installing Windows is smaller than the recommended size, expand the
partition size or add another hard disk drive.
Note
 The above paging file sizes are recommended for collecting debug
information (dump file). The initial size of the Windows partition paging file
must be large enough to store dump files.
Make sure you set a sufficient paging file size. If the paging file is insufficient,
there will be a virtual memory shortage that may result in an inability to
collect correct debug information.
 Regardless of the sizes of internal memory and write debug information, the
maximum size of the dump file is "size of internal memory + 300 MB".
 When installing other applications or other items, add the amount of space
needed by the application to the partition.
