Configure NVMe RAID Using BRU

BRU on Oracle AMD Platforms
On Exadata Server X10M, BRU is employed in "Native" mode, which is based on
Linux RAID metadata version 1.2. Oracle AMD platforms do not support IMSM (Intel©
Matrix Storage Manager) containers and metadata, which are Intel VROC features.
Enabling/Disabling BRU
By default, BRU is disabled in UEFI. There is no BRU enable/disable switch in the
UEFI menus. BRU is enabled by modifying the UEFI configuration in Oracle ILOM
'expert mode'. You must stop the system to perform this procedure.
BRU (Boot RAID on UEFI) enables Exadata Server X10M to boot from NVMe RAID1
devices. BRU replaces the boot device discovery functionality provided by Intel©
VROC (Virtual RAID on CPU). Note that BRU is not a feature-for-feature replacement
of VROC. BRU does not provide RAID device configuration and management
capability. The RAID1 boot devices used by BRU are created with Linux mdadm utility.
The underlying RAID functionality is managed with Linux mdadm utility and md driver.
The Configure NVMe RAID1 Boot Devices procedure configures a RAID1 volume so
that you can install Oracle Linux. Boot RAID on UEFI (BRU), implements a UEFI driver
that identifies a bootable NVMe M.2 RAID1 volume in the UEFI environment.
OnExadata Server X10M, BRU uses native Linux RAID1 metadata (version 1.2) and is
fully compatible with mdadm utilities in Linux.
