Large Files

[Kiran N. Mehta]

In what way is the OS kernel bit-width related to the largest file you can create?

[Andreas Voss]

I think the largest files size depends on the OS release and the typ/options of the filesystem where the file is going to create.

Hi

The kernel bit-width is mostly related to data transfer rate and the CPU clock speed.
File sizes are relatively dependent on inode and file kernel parameters.
The newer versions of HP O/S can support 128Gbyte of file size and disk storage capacity.

As mentioned before, the running kernel's bit size is not related to the size of files or filesystems. File sizes on dependent on the filesystem code, which in turn is tied to revisions of HP-UX. Here is a table that will help:

rev. file filesystem
10.01 2gb 4gb
10.10 2gb 128gb
10.20 128gb 128gb
11.0 1tb 1tb

These are tested and supported limits. The code may allow for much larger values to be used. For filesystems larger than 10-50 Gb, the preference is to use vxfs rather than hfs due to the length of time fsck will require to verify/fix a large filesystem.
