<h1 class="topictitle1">Benefits of virtual storage</h1>
<div><p>Virtual storage can help eliminate media errors and user intervention
and can increase system availability.</p>
<p>Virtual storage also provides the following advantages:</p>
<div class="section"><h4 class="sectiontitle">Electronic distribution</h4><p>You can use virtual storage
to simplify software and data distribution by creating tape, CD or DVD images
on your server. You can distribute these images electronically using file
transfer protocol (FTP, FTP SSL) or other electronic methods. On the server
that receives the images, you can mount the images in a virtual device for
easy access. You can also receive or distribute programming temporary fixes
(PTFs) electronically.</p>
</div>
<div class="section"><h4 class="sectiontitle">Object signing</h4><p>You can secure a virtual image by
giving it a digital signature, i5/OS™ provides support for using digital
certificates to digitally sign objects. A digital signature on an object is
created by using a form of cryptography and is like a personal signature on
a written document. You need to create a digital signature to use object signing
and signature verification.</p>
</div>
<div class="section"><h4 class="sectiontitle">CD, DVD, and tape creation</h4><p>You can use virtual storage
to create actual media using the DUPOPT and DUPTAP commands to duplicate the
virtual images to physical media.</p>
