<h1 class="topictitle1">Determine which systems to use for logical replication</h1>
|
|
<div><p>When you are determining which systems to use for logical replication,
|
|
there are several key considerations.</p>
|
|
<p>These considerations are:</p>
|
|
<ul><li>Performance capacity</li>
|
|
<li>Disk capacity</li>
|
|
<li>Critical data</li>
|
|
<li>Disaster prevention</li>
|
|
</ul>
|
|
<p>If your system fails over, you need to know what data and applications
|
|
you have running on your primary system and your backup system. You want to
|
|
put the critical data on the system that is most capable of handling the workload
|
|
in case it fails over. You do not want to run out of disk space. If your primary
|
|
system runs out of space and fails over, it is highly likely that your backup
|
|
system is also going to fail over due to lack of disk space. To ensure your
|
|
data center is not completely destroyed in case of a natural disaster, such
|
|
as a flood, tornado, or hurricane, you should locate the replicated system
|
|
in a remote location.</p>
