<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>
