<h1 class="topictitle1">Integrated file system</h1>
|
||
|
|
<div><p>The integrated file system is a part of i5/OS™ that supports stream input/output
|
||
|
|
and storage management similar to personal computer and UNIX<sup>®</sup> operating
|
||
|
|
systems, while providing an integrating structure over all information stored
|
||
|
|
in your server. </p>
|
||
|
|
<div class="p">The integrated file system comprises 11 file systems, each with its own
|
||
|
|
set of logical structures and rules for interacting with information in storage.
|
||
|
|
Key features of the integrated file system include the following: <ul><li>Support for storing information in stream files that can 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. 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
|
||
|
|
similar to common PC file structures. A path specified through the directories
|
||
|
|
to an object accesses the object.</li>
|
||
|
|
<li>A common interface that allows users and applications to access not only
|
||
|
|
the stream files but also database files, documents, and other objects that
|
||
|
|
are stored in your server.</li>
|
||
|
|
<li>A common view of stream files that are stored locally on your server,
|
||
|
|
Integrated xSeries<sup>®</sup> Server
|
||
|
|
for iSeries™,
|
||
|
|
or a remote Windows NT<sup>®</sup> server. Stream files can also be stored
|
||
|
|
remotely on a local area network (LAN) server, a Novell NetWare server, another
|
||
|
|
remote iSeries server,
|
||
|
|
or a Network File System server.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The integrated file system enhances the already extensive data management
|
||
|
|
capabilities of i5/OS with
|
||
|
|
additional capabilities to better support emerging and future forms of information
|
||
|
|
processing, such as client/server, open systems, and multimedia. </p>
|
||
|
|
<div class="p">The integrated file system enables you to do the following: <ul><li>Attain fast access to i5/OS data, especially for applications such as iSeries Access
|
||
|
|
that use the i5/OS file
|
||
|
|
server.</li>
|
||
|
|
<li>Handle types of stream data, such as images, audio, and video more efficiently.</li>
|
||
|
|
<li>Use a file system base and a directory base for supporting UNIX-based
|
||
|
|
open system standards, such as Portable Operating System Interface for Computer
|
||
|
|
Environments (POSIX) and XPG. This file structure and this directory structure
|
||
|
|
also provides a familiar environment for users of PC operating systems such
|
||
|
|
as Disk Operating System (DOS), and Windows<sup>®</sup> operating systems.</li>
|
||
|
|
<li>Gain access to file support with unique capabilities (such as record-oriented
|
||
|
|
database files, UNIX-based stream files, and file serving) to be handled as
|
||
|
|
separate file systems, while allowing them all to be managed through a common
|
||
|
|
interface.</li>
|
||
|
|
</ul>
|
||
|
|

|

<p>LAN-attached optical devices do not support this interface. </p>
