Fujitsu ETERNUS DX S5 Series, Design Manual

Page: 185 / 335

Note
During the design phase
• The types of characters that can be used for the owner name and group name are alphanumeric
characters (or US-ASCII codes) and symbols from the space character (0x20) to the tilde "~" (0x7E). Note
that "?" (0x3F) and "\" (0x5C) cannot be used.
• The types of characters that can be used for CIFS Allowed Hosts, CIFS Denied Hosts, and NFS Allowed
Hosts are alphanumeric characters (or US-ASCII codes) and symbols from the space character (0x20) to
the tilde "~" (0x7E). Note that "?" (0x3F) and "\" (0x5C) cannot be used.
• The owner and group of a shared folder cannot be assigned with the character strings below because
they are reserved words. This applies even if the character strings are registered in the authentication
server.

Character Set
For the ETERNUS DX in a Unified configuration, UTF-8 is used as the character set.
File names and directory names are set with the UTF-8 character set.
Note
During the operation phase
•
Specifications for the character set and the length of the file name depends on the OS. File names must
be taken into consideration when sharing files.
- The following table shows the character set and the file name length for Windows and UNIX/Linux.
OS Character set File name length
Windows UTF-8 (Unicode) Up to 255 bytes
UNIX/Linux UTF-8 Up to 255 bytes
- Note that the following characters cannot be used for file names in Windows.
" (double quotation mark), * (asterisk), / (slash), : (colon), <, >, ?, \, |
•
The maximum length for a UNIX/Linux directory path name is 1,005 bytes.
Although UNIX/Linux allows up to 1,023 bytes for the directory path name, internal processes for the
ETERNUS DX uses 18 bytes so the maximum length for path names are reduced to 1,005 bytes.
