<div><p>If your server uses mirroring or an implementation of a RAID-5
|
|
technique on the disk units in the system ASP, your installation time can
|
|
be longer. </p>
|
|
<p>This amount of time will vary depending on your configuration, but if the
|
|
disk units are protected with RAID-5, the total installation time <span>(for
|
|
Licensed Internal Code, the <span class="keyword">i5/OS™</span> operating
|
|
system, and licensed programs)</span> will be approximately 15 percent longer.
|
|
If the disk units are mirror protected, the total installation time will be
|
|
approximately 10 percent longer. Mirroring and implementations of the RAID-5
|
|
techniques do not affect the duration of save operations.</p>
|
|
<p>Using the percents given, include a time estimate for your server in <a href="estimatetimeupgrade.htm#estimatetimeupgrade">Checklist: Estimating installation time</a>.</p>
