AMD RAID Configuration

The following are the RAID levels supported by RAIDXpert2.

RAID 0 (Striping) breaks the data into blocks which are written to separate hard drives. Spreading the hard drive I/O load across independent channels greatly improves I/O performance.
RAID 1 (Mirroring) provides data redundancy by mirroring data between the hard drives and provides enhanced read performance.
RAID 10 (Striped RAID1 Sets) uses four hard drives to create a combination of RAID 0 and 1 by forming a RAID 0 array from two RAID 1 arrays.
Volume (JBOD) provides the ability to link-together storage from one or several disks, regardless of the size of the space on those disks. Useful in scavenging space on disks unused by other disks in the array. Does not provide performance benefits or data redundancy.
RAIDABLE (also known as RAID Ready) allows the user to add more storage space or create a redundant array after a system is installed.

RAID level comparison

	RAID 0	RAID 1	RAID 10
Minimum # drives	2	2	4
Data protection	None	Excellent	Excellent
Read performance	Excellent	OK	OK
Write performance	Excellent	Good	Good
Capacity utilization	100%	50%	50%

Important: All the information/ volumes/ pictures listed in your system might differ from the illustrations in this appendix.

Enabling RAIDXpert2 Configuration Utility

To enter the RAIDXpert2 Configuration Utility menu

Power on and press Delete key to enter BIOS Setup menu.
Press F7 to switch to Advanced mode from EZ mode.
Go to BIOS > SETTINGS > Advanced > Integrated Peripherals > SATA Mode and change setting to RAID Mode.
Go to BIOS > SETTINGS > Advanced > Windows OS Configuration > BIOS UEFI/CSM Mode and change setting to UEFI.
Press F10 to save configuration and exit, and then reboot and press Delete key to enter BIOS Setup menu.
Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility sub-menu.

Initializing Disks

New disks and legacy disks must be initialized before they can be used to create an AMD-RAID array. Initialization writes AMD-RAID configuration information (metadata) to a disk.

Important

If a disk is part of an AMD-RAID array, the disk cannot be selected for initialization. To initial the disk anyway, delete the AMD-RAID array. Data on the disk is deleted during initialization so ensure the correct disks are chosen to initialize.
A legacy disk can contain valid data. When a legacy disk is initialized, all data on the disk is lost.

To initialize disks

As previously mentioned, enable RAIDXpert2 Configuration Utility.
Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Physical Disk Management > Select Physical Disk Operations > Initialize Disk sub-menu.
Select desired disks by changing the Physical Disk setting to Enabled.
Select OK, then press Enter.
Review the warning message, if you want to proceed, select YES, then press Enter.
Initialization takes 10 to 15 seconds per disk. During initialization, a complete rescan of all channels is done automatically.

Creating Arrays

Arrays can be created after the disks are initialized.

Important

For redundant arrays, the Create process is not started until after the operating system and AMD-RAID OS drivers have been installed and the system has booted to the operating system. However, the arrays are immediately available to use for either a bootable array or a data array.
Array numbers are valid only for a given boot and might be different in the RAIDXpert2 Configuration Utility and RAIDXpert2. If a permanent label is required, use the RAIDXpert2 Web GUI Array Naming feature.
At any point in the procedure, return to a prior window by pressing ESC.
If the system is booted from an AMD-RAID bootable array, the first array in the Arrays section must be the bootable array. The system boots only from the first array in the Arrays section.

To create an array

As previously mentioned, enable RAIDXpert2 Configuration Utility.
Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Array Management > Create Array sub-menu.
Select the RAID level from the Select RAID Level drop down menu.
Enter Select Physical Disks sub-menu, select member disks by changing the Physical Disk setting to Enabled.
Select Apply Changes, then press Enter to apply and go back to previous sub-menu.
Change the Select CacheTagSize, Read Cache Policy and Write Cache Policy settings according to your needs.
Select Create Array, then press Enter.

Deleting Arrays

Important

Deleting an array permanently destroys all data that is on the array. This action cannot be undone and it is very unlikely that the data can be recovered.
Do not delete the first array listed in the Arrays section, if it is the AMD-RAID bootable array. Doing this deletes the operating system and AMD-RAID files.

To delete an array

As previously mentioned, enable RAIDXpert2 Configuration Utility.
Go to BIOS > SETTINGS > Advanced > RAIDXpert2 Configuration Utility > Array Management > Delete Array sub-menu.
Select the desired array and change the setting to Enabled.
Enter Delete Array(s) sub-menu.
Review the warning message, if you want to proceed, Select Confirm and change the setting to Enabled.
Select YES then press Enter.

Setup Guide

To set up the MSI PRO-VDH WIFI ProSeries Motherboard B550M,

Start by unboxing and preparing all the components.
Mount the motherboard onto the case stand-offs and secure it with screws.
Connect the CPU, CPU cooler, and RAM to their respective slots.
Install the storage devices (HDD/SSD) into the SATA ports or M.2 slots.
Connect the power cables from the power supply unit to the motherboard.
Install the graphics card into the PCIe x16 slot if necessary.
Connect all front panel headers, USB ports, and other peripherals to their corresponding headers on the motherboard.
Boot up the system and enter the BIOS to configure settings as needed.

Installing RAID Driver

New Operating System Installation
The following details the installation of the drivers while installing operating system.

During the operating system installation, after selecting the location to install Windows click on Load driver button to install a third party RAID driver.
When prompted, insert the USB flash drive with AMD RAID Drivers and then click Browse.
- To make an AMD RAID Drivers USB flash drive. Insert the MSI Driver Disc into the optical drive. Copy all the contents in \\Storage\AMD\
Navigate to the directory containing the saved AMD RAID drivers, then click OK.
Select the (rcbottom.inf) driver, click Next.
When prompted, click OK.
Click Browse and navigate to the directory containing the saved AMD RAID drivers again, then click OK.
Select the (rcraid.inf) driver, click Next.
You have successfully installed the RAID driver, and Windows setup should continue.
Leave the disk/ USB drive in the computer until the system reboots itself. Windows setup will need to copy the files after the RAID volume is formatted, and Windows setup starts copying files.
