file system
On an HP NonStop™ system, the Guardian file system for a node has a mount point 
and is a subset of the OSS virtual file system. The entire Guardian file system 
therefore could be viewed as a single fileset. However, each volume, and each 
process of subtype 30, within the Guardian file system is actually a separate fileset.
The term “file system” is often used interchangeably with “fileset” in UNIX publications. 
file system. In the Open System Services (OSS) environment, a collection of files and file 
attributes. A file system provides the namespace for the file serial numbers that 
uniquely identify its files. Open System Services provides a file system (see also 
ISO/IEC IS 9945-1:1990 [ANSI/IEEE Std. 1003.1-1990], Clause 2.2.2.38); the 
Guardian application program interface (API) provides a file system; and OSS Network 
File System (NFS) provides a file system. (OSS NFS filenames and pathnames are 
governed by slightly different rules than OSS filenames and pathnames.) Within the 
OSS and OSS NFS file systems, filesets exist as manageable objects.
On an HP NonStop™ system, the Guardian file system for a node is a subset of the 
OSS virtual file system. Traditionally, the API for file access in the Guardian 
environment is referred to as the “Guardian file system.”
In some UNIX and NFS implementations, the term “file system” means the same thing 
as “fileset.” That is, a file system is a logical grouping of files that, except for the root of 
the file system, can be contained only by directories within the file system. See also 
fileset.
File Transfer, Access, and Management (FTAM). The Open Systems Interconnection 
(OSI) standard developed by the International Organization for Standardization (ISO) 
for network file exchange and management services.
file transfer protocol (FTP). (1) The Internet-standard, high-level protocol for transferring 
files from one machine to another. The server side requires the client to supply a logon 
identifier and password before it honors requests. FTP makes no assumptions about 
the file-naming structure of the source and destination systems, and it allows the file 
names of each system to be represented in the vernacular. (2) The application used to 
send complete files over Transmission Control Protocol/Internet Protocol (TCP/IP) 
services.
filler panel. A blank faceplate that is installed in place of a ServerNet adapter or plug-in 
card (PIC) to ensure proper ventilation.
fingerprint. A unique identifier calculated for a file and displayed in hexadecimal format.
FIPS. A Federal Information Processing Standard of the United States government.
FIPS 151-1. The Federal Information Processing Standard that specifies the requirements 
for conformance to an older draft of POSIX.1 (IEEE Std. 1003.1-1988) than the version 
adopted as ISO/IEC IS 9945-1:1990 and imposes some additional requirements.
