5-6 Installing the Operating System with Express Setup
About the System Partition Size
When the system is Windows Server 2008 32-bit (x86) Edition
Required partition size = size required to install OS + paging file size + dump file size + application size
Size required to install OS = 6,300MB (Full Installation)
or
= 2,200MB (Server Core Installation)
Paging file size (recommended) = Installed memory size x 1.5
Dump file size = Installed memory size + 300MB
Application size = Required 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 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 the one required to install the OS and paging file, expand
the partition size or use 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.
