About the System Partition Size
The system partition size can be calculated from the following formula.
When the system is Windows Server 2008 64-bit (x64) Edition:
Required partition size
= Size required to install OS + paging file size + dump file size + application size
Size required to install OS
Paging file size (recommended) = Installed memory size * 1.5
Dump file size
Application size
IMPORTANT:
The above-mentioned paging file size is recommended for

collecting debug information (memory dump). The paging file with
initial size large enough to store the dump file in the boot drive is
required.
Correct debug information might not be able to be collected due to
virtual memory shortage when the paging file is insufficient, so set
an enough size of the paging file with the entire system.
Regardless of the size of the mounted memory, or the Write

debugging information (type of memory dump), the maximum size
of the dump file is 'The size of the mounted memory + 300MB'.
If you install any application program or the like, add necessary

space to the partition to install these programs.
