There are two types of RAID, hardware and software RAID:
■
Hardware RAID
- A host bus adapter (HBA) manages the array and presents the volumes
to the OS as simple disks. Hardware RAID unburdens the OS, and is more robust than
software RAID.
The Oracle Storage 12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16-Port on your
server supports hardware RAID. For instructions, see “Configure RAID on Oracle Storage
12 Gb SAS PCIe RAID Host Bus Adapter, Internal 16 Port” on page 92 .
■
Software RAID - The OS manages the array, which is created and configured using
an OS. In a typical use case, you boot an OS on one device to create a software RAID
volume on a different device. For details, refer to the instructions in your operating system
documentation.
Note the following conditions:
■
Your server might have other storage devices where you can install an OS as well. These
might or might not support or require RAID; however, if you do configure a RAID volume
on these devices, you must do so before installing an OS. For instructions, refer to the
documentation for the device, and Oracle Server X8-8 Operating Systems Installation
Guide .
■
The UEFI BIOS utility in your server does not display items in the boot list until after an
OS is installed on the storage device and then the server is booted. This is unlike older BIOS
utilities that display devices where you can install an OS.
To see devices where you can install an OS, you have to use an OS installation program.
