When the system is Windows Server 2008 32-bit (x86) Edition
Required partition size
Size required to install OS
Paging file size (recommended) = Installed memory size x 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.
The maximum paging file size which can be set on one partition is
4095MB. If the above paging file size exceeds 4095MB, specify
4095MB for the paging file size.
The maximum dump file size for the system with more than 2GB
memory mounted is '2048MB + 300MB'.
If you install any application program or the like, add necessary
space to the partition to install these programs.
Example:
The partition size required for a system with an installed memory size of 512 MB and a full
installation of the operating system:
6,300MB + (512MB x 1.5) + 512MB + 300MB + application size
= 7,880MB + application size.
If the partition where the operating system is installed is smaller than that required to install the OS
and paging file, expand the partition size or utilize a larger disk. If your system does not have a
sufficient dump file size, divide the required file space into multiple disks by performing the steps
below:
1.
Set the partition size to a size sufficient to install the OS and paging file.
2.
See "Setting for Solving Problems" to write the debug information of the dump file on to
another disk.
If there is not enough disk space to write the debug information, add another disk for the dump file.
Installing the Operating System with Express Setup 5-7
= size required to install OS + paging file size + dump
file size + application size
= 6,300MB (Full Installation)
or
= 2,200MB (Server Core Installation)
= Installed memory size + 300MB
= Required size
