<h1> Choosing
  between Express and Custom configuration</h1>
<p> In the Configuration wizard, you can choose from two paths to configure your
  controller:<br>
<ul>
  <li>Click <b>Express configuration</b> for a quick and easy path for you to
    automatically configure your controller. This path creates the most efficient
    configuration based on the number and capacity of the ready physical drives
    available in your system. If four or more ready drives of the same capacity
    are available, this choice also will define a <a href="ghsd.htm">hot-spare
    drive</a>.
    <p> Express configuration does the following:</p>
    <ul>
      <li>Creates one logical device, up to 256 terabytes (TB) (2 terabytes for HostRAID controllers) maximum, by grouping
        together same-sized physical drives. <br>
        <b><br>
        <img src="images/note.gif" width="15" height="17"> Note: </b> If the physical
        drive size exceeds 256 terabytes (TB) (2 terabytes for HostRAID controllers), Express configuration removes drives until the
        size is less than 256 terabytes (TB) (2 terabytes for HostRAID controllers). It creates an additional logical device with the
        left-over drive(s). <br>
        <br>
      </li>
      <li>Assigns a RAID level based on the number of available physical drives:<br>
        <br>
        <ul>
          <li>A logical device with a single physical drive is assigned RAID level-0.</li>
          <li>A logical device with two physical drives is assigned RAID level-1.
          </li>
          <li> A logical device with three physical drives is assigned RAID level-5.<br>
          </li>
        </ul>
        <br>
        <img src="images/hstraid1.gif" width="37" height="32">&nbsp;For HostRAID
        controllers, Express configuration creates a RAID level-1 logical device.<br>
        <br>
      </li>
      <li>Designates a hot-spare drive for the controller. If four or more ready
        drives are available, the largest drive will be designated the hot-spare
        drive. <br>
      </li>
    </ul>
    <p><b><img src="images/note.gif" width="15" height="17"> Note: </b>When you
      choose Express configuration, you have the opportunity to review and approve
      the configuration before the HP Storage Manager applies the configuration.
      If you need to modify the configuration, you can do it from the configuration
      summary.<br>
      <br>
    </p>
  </li>
  <li>Click <b> Custom configuration</b> for a path that lets you manually configure
    your controller. Choose this path to do any of the following:<br>
    <br>
    <ul>
      <li><a href="wselrdcc.htm">Define the RAID level</a> of the logical devices.<br>
      </li>
      <li>Select the <a href="wcfgldcc.htm">physical drives that you want to include
        for each logical device</a>.<br>
      </li>
      <li>Define the <a href="wcfgldcc.htm">number and size of the logical devices.</a><br>
      </li>
      <li><a href="wadvstcc.htm">Fine tune your configuration</a> for optimal
        performance<br>
      </li>
      <li>Review the <a href="wsummcc.htm">configuration summary</a>.</li>
    </ul>
  </li>
</ul>
<p>When you are ready to continue, click <strong>Next</strong>.<br>
