<div><p>Learn about the file server, including file server programs and
how it works with the integrated file system.</p>
<p>The integrated file system is a part of the base iSeries™ server operating system that
supports stream input/output and storage management, similar to personal computer
and UNIX<sup>®</sup> operating
systems. The integrated file system also integrates all information that is
stored on the iSeries server. iSeries servers
can support several different file systems with similar interfaces. A file
system allows users and applications to access specific segments of storage
that are organized as file, directory, library, and object logical units.</p>
<p>The file server allows clients to store and access information, such as
files and programs, located on the iSeries server. The file sever interfaces
with the integrated file system and allows clients to use their own interface
to interact with the file systems, rather than using the integrated file system
user interfaces and APIs. The file server can give clients access to all of
the iSeries file
systems or just the Document Library Services File System (QDLS), depending
on the support provided by the client product.</p>
<p>The key features of the integrated file system are the following:</p>
<ul><li>Support for storing information in stream files, which are files that
contain long, continuous strings of data. These strings of data might be,
for example, the text of a document or the picture elements in a picture.
Documents that are stored in iSeries folders are stream files. Other examples
of stream files are PC files and the files in UNIX systems. The stream file support is
designed for efficient use in client/server applications.</li>
<li>A hierarchical directory structure that allows objects to be organized
like branches of a tree. To access an object, specify the path from the directories
to the object.</li>
<li>A common interface that allows users and applications to access stream
files, database files, documents, and other objects that are stored on the iSeries server.</li>
</ul>
<p>For a list of iSeries file
systems, see the Work with file systems topic collection. For more information
about the integrated file system, see the Integrated file system topic collection.</p>
