Precautions for system partition size
The system partition size can be calculated by using the following way.
(OS size) + (paging file size) + (dump file size) + (application size)
Server with a GUI
OS size = 9,400MB
Paging file size (recommended) = installed memory size × 1.5
Dump file size = installed memory size + 400MB
Application size = as required by the application
Server Core installations
OS size = 6,300MB
Paging file size (recommended) = installed memory size × 1.5
Dump file size = installed memory size + 400MB
Application size = as required by the application
For example, if the installed memory size is 1 GB (1,024 MB) and Server with a GUI is selected,
the partition size is calculated as follows:
9,400MB + (1,024MB × 1.5) + 1,024MB+ 400MB+ application size
= 12,360MB + 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.
The following partition sizes are recommended.
Server with a GUI : 32,768MB(32GB) or more
Server Core installations : 32,768MB(32GB) or more
*1 GB = 1,024 MB
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 + 400 MB".
When installing other applications or other items, add the amount of
space needed by the application to the partition.
