Media Such As Dat; Partition Size - NEC 140He User Manual

Media such as DAT

During the operating system installation, do not attach unnecessary media for operating system installation to the
system, such as DAT.

Partition Size

The size for the partition that the system is to be installed can be calculated from the following formula.
Size necessary to install the system + Paging File Size + Dump File Size + Application Size
Size necessary to install the system = 4100 MB
Paging File Size (Recommended) = Mounted 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 the paging file size large enough for
the entire system.
The dump file size for the system with more than 2 GB memory mounted is '2048 MB +
1 MB'.
If you install any application program, add necessary space to the partition to install
these programs.
For example, if the mounted memory size is 512 MB, the partition size will be calculated by the above formula as
follows:
4100 MB + (512 MB * 1.5) + (512 MB + 1 MB) + Application Size
= 5381 MB + Application Size
Dividing into the partition of the recommended size into multiple disks as written below will solve problem that it
cannot be reserved in one disk.
1.
Set the "Size required for installation + Paging file size".
2.
See Chapter 5 and set that debugging information (equivalent to the dump file size) is to be written to a
separate disk.
(If the disk does not have enough free space to enable the file size to be written, then after installing the
system using the "Size required for installation + Paging file size," install an additional new disk.)
= Mounted Memory Size + 1 MB
= Required Size
