|
||
|
|
<p>A network server storage space (NWSSTG) represents a virtual disk drive
|
||
|
|
that the server uses. See <a href="rzahqscixsandixa.htm#rzahqscixapic">Figure 13</a> and <a href="rzahqscixsandixa.htm#ixsixaconf">Figure 14</a> .
|
||
|
|
Virtual disk drives can vary in size from 1 MB to 1000 GB each. Up to 64
|
||
|
|
virtual disk drives can be linked to a server, depending on the server configuration,
|
||
|
|
so the storage capacity of an integrated server can range from several gigabytes
|
||
|
|
to many terabytes. The virtual disk drives are first created as stand-alone
|
||
|
|
objects and then linked to the integrated server by identifying the NWSD of
|
||
|
|
the integrated server that uses them.</p>
|
||
|
|
<p>Each server will have at least 2 virtual disk drives that are automatically
|
||
|
|
created by the INSWNTSVR command, but can also have user-defined virtual disk
|
||
|
|
drives.</p>
|
||
|
|
<ul>
|
||
|
|
<li>The system drive (typically the C: drive) contains the Windows server
|
||
|
|
operating system (such as Windows Server 2003).</li>
|
||
|
|
<li>The install drive (typically the D: drive) contains a copy of the Windows
|
||
|
|
server installation media as well as the portion of the i5/OS™ Integrated
|
||
|
|
Server Support (product 5722-SS1 option 29) code that runs on the Windows
|
||
|
|
server. The install drive is used during the Windows installation process
|
||
|
|
and is also used every time the server is started to pass configuration information
|
||
|
|
from i5/OS to the server.</li>
|
||
|
|
<li>Additional user-defined drives are typically used for server applications
|
||
|
|
and data.</li></ul>
|
||
|
|
<p>The actual disk storage for the virtual disk drives is allocated from the i5/OS integrated file system (IFS). The virtual disk drives can be allocated
|
||
|
|
from the default system disk pool (also known as the system auxiliary storage
|
||
|
|
pool, or system ASP) or from a user defined disk pool or an independent disk
|
||
|
|
pool (IASP).</p>
|
||
|
|
<p>See <a href="rzahqasdpo.htm#rzahqasdpo">Manage storage</a> for more information about virtual disk drives.</p>

|

|
<ol type="1">
|
||
|
|
<li>Since virtual disk drives are objects in the i5/OS IFS, an entire virtual disk drive image
|
||
|
|
can be backed up and restored using the i5/OS Save (SAV) and Restore (RST) commands.
|
||
|
|
Files on a virtual disk drive can be backed up individually from i5/OS using file
|
||
|
|
level backup with the Network Client (QNTC) file system in the IFS or using
|
||
|
|
a native Windows backup application. See <a href="rzahqbkopo.htm#rzahqbkopo">Back up and recover integrated Windows servers</a> for more
|
||
|
|
information.</li>
|
||
|
|
<li>Even though storage spaces are allocated out of IFS, storage operations
|
||
|
|
are not performed by IFS while the integrated server is varied on. This means
|
||
|
|
that operations like journaling are not enabled.</li>
