Your server may have been shipped with an internal host bus adapter (HBA) card installed. To learn more about the internal HBA card, see the Oracle Storage 12 Gb SAS PCIe RAID HBA, internal: 16 port and 2 GB memory Internal Installation Guide at http://docs.oracle.com/cd/E52363_01/index.html.
Use the following guidelines to determine how to configure storage drives.
If your server comes with a RAID internal HBA card installed and any amount of HDDs or SDDs, then the system is shipped with each HDD or SSD as part of its own RAID 0 configuration.
To install an OS, ensure that the drive where you want to install the OS is visible to the system.
To install and boot an OS, you need to create a RAID volume on the drive.
If you do not want to use a RAID array, configure a drive as a RAID 0 volume.
You can use the BIOS RAID configuration utilities to configure RAID on the internal HBA card. See Configuring RAID.
The following table lists the disk requirements for each supported RAID level:
After you create a bootable RAID volume, install the OS. For details, refer to the operating system installation guide in http://www.oracle.com/goto/x7-2/docs or http://www.oracle.com/goto/x7-2l/docs.
