# Choosing between Express and Custom configuration

In the Configuration wizard, you can choose from two paths to configure your integrated RAID controller subsystem:

- Click Express configuration for a quick and easy path for you to automatically configure your integrated RAID controller.

  Express configuration does the following:

  - Creates an array by grouping together the first two physical drives that appear in the ServeRAID Manager tree.
  - Creates a RAID level-1 logical drive.

  Note: If you click Express, you will have the opportunity to review and approve the configuration before the ServeRAID Manager applies the configuration. If you need to modify the configuration, you can do so from the configuration summary.

- Click Custom configuration for a path that lets you to manually configure your integrated RAID controller. Choose this path to do any of the following:
  - Configure your controller manually.
  - Select the two physical drives that you want to configure.
  - Create a hot-spare drive.
  - Preserve data on a mirror primary drive.
  Using this path, you can:
  - Select the physical drives that you want to include in the array and that you want to use as a hot-spare drive.
  - Review the configuration summary.

After you choose your path, click Next.
