</p>
<p>
This setting is required to create a Multi-AZ DB cluster.
</p>
<p>
When specified for a Multi-AZ DB cluster, a value for the <code>Iops</code> parameter is required.
</p>
<p>
Valid for Cluster Type: Aurora DB clusters and Multi-AZ DB clusters
</p>
<p>
Valid Values:
</p>
<ul>
<li>
<p>
Aurora DB clusters - <code>aurora | aurora-iopt1</code>
</p>
</li>
<li>
<p>
Multi-AZ DB clusters - <code>io1 | io2 | gp3</code>
</p>
</li>
</ul>
<p>
Default:
</p>
<ul>
<li>
<p>
Aurora DB clusters - <code>aurora</code>
</p>
</li>
<li>
<p>
Multi-AZ DB clusters - <code>io1</code>
</p>
</li>
</ul>
<note>
<p>
When you create an Aurora DB cluster with the storage type set to <code>aurora-iopt1</code>, the storage type is
returned in the response. The storage type isn't returned when you set it to <code>aurora</code>.
