By default, each physical drive on the server is configured as a RAID 0 volume. If you ordered the preinstalled Oracle Solaris, Oracle Linux, or Oracle VM Server operating system (OS), the OS was installed on one of these RAID 0 drives. You have the option of reconfiguring the server drives to suit your environment. However, reconfiguring the drives might erase the preinstalled OS and any other data on the drives.
