INFODOC ID: 15933 
STATUS: Issued 

SYNOPSIS: Maximum file and file system sizes of SunOS/Solaris 
DETAIL DESCRIPTION: 

This Infodoc lists the maximum single file and file system size of 4.1.x
and 
Solaris 2.x up to 2.6. 

OS RELEASE              SINGLE FILE             FILE SYSTEM 
===============         ===========             =========== 
4.1.x                      2 GB                     2 GB 
4.1.x + ODS                2 GB                     1 TB 
Solaris 2.0-2.5.1          2 GB                     1 TB 
Solaris 2 + SDS            2 GB                     1 TB 
Solaris 2.6                ~800 GB                  1 TB 

A single file of Solaris 2.6 is limited to "about" 800 GB because the 
file MUST fit inside a file system. The file system is nominally 1 TB, 
but in fact one must create enough overhead in such a large file
system 
that the largest single file ends up being "about" 800 GB. 
(part of this is a bug, but even if bug-free a single file can't be 1 TB) 

Note that in Solaris 2.6, the swap and tmpfs file system are still
limited 
to 2 GB.  Also note that the root file system is limited to ~2 GB on 
all but Ultras due to an OBP limitation (~1 GB on systems with OBP 
versions 1.0->2.6).
