4. Click Next. The Disk Selection page appears.
5.  Select the drive that you want to rebuild by clicking it from the list, then click Next.
The Completing the NVIDIA Rebuild Array page appears.
6. Click Finish. The array rebuilding starts after a few seconds, and a small pop-up
message appears towards the bottom right corner of the screen as shown in the
figure below.
During the rebuilding process, the NVRAID Management utility screen shows the
status under the System Tasks...

More About Rebuilding Arrays
• Rebuilding Occurs in the Background
The rebuilding process is very slow (it can take up to a day) and occurs in the
background so as not to affect the performance of the system.
• Rebuilding Applies Only to RAID 1 or RAID 0+1 Arrays
Rebuilding an array works only when using RAID1 and/or RAID 0+1. Rebuilding does
not apply to RAID 0 and JBOD arrays.
• You Can Use Any Available Free Disk
You can rebuild a mirrored array using any available Free Disk...

MSI Reminds You...
All the information/volumes listed in your system might differ from the
illustrations in this appendix. Silicon Image’s SATARAID5
TM software provides Serial ATA RAID 0
(Striping), RAID 1 (Mirroring), RAID 5 (Parity RAID), RAID 10 (Striping and
Mirroring), and JBOD (just a bunch of disks) functionality to enhance the
industry’s leading PCI-to-SATA host controller...

Introduction
RAID - Redundant Array of Independent Disks
RAID technology manages multiple disk drives to enhance I/O performance
and provide redundancy in order to withstand the failure of any individual member,
without loss of data. SATA RAID provides two RAID Set types, Striping (RAID 0)
and Mirroring (RAID 1).
RAID 0 (Striping)
Striping is a performance-oriented, non-redundant data mapping technique.
While Striping is discussed as a RAID Set type, it actually does not provide...

Silicon Image SATARAID5TM Introduction
The data is written to RAID Group A, which is striped (RAID 0). This allows
maximum speed. The data is then mirrored to another RAID 0 striped set, which is
Set B in the figure above. This provides data redundancy (RAID 1), and thus
increased data security. Under certain circumstances, a RAID 10 set can sustain
multiple simultaneous drive failures.
RAID 5 (Parity RAID)
Parity or RAID 5 adds fault tolerance to Disk Striping by including parity information
with...

Creating and Deleting Legacy RAID Groups with BIOS Utility
Legacy RAID sets and JBOD can be created and managed by either the BIOS utility
or the SATARAID5 GUI. New RAID groups must be created and managed by the
SATARAID5 GUI.
During boot up, a screen similar to that below will appear for about 5 seconds.
Press CTRL+S or the F4 key to enter the BIOS RAID utility.
The RAID Utility menu screen will be displayed. A brief description of each section
is presented on...

Create RAID Group is used to create a new legacy RAID Set or for allocating
legacy spare drives.
Delete RAID Group is used to delete a legacy RAID Set or to deallocate a legacy
spare drive.
Rebuild RAID 1 Set is used to initiate the rebuild of a RAID 1 set after, for
example, a drive in the Group has been replaced.
Resolve Conflicts is used to automatically find the member drives of a RAID set
which has been disrupted (physical drives
swapped around, for example) and restore the...

Creating RAID Groups
As previously discussed, the Silicon Image SATA host adapter supports RAID 0, 1,
5, 10, and JBOD configurations. The selection of the RAID level to be used should
be based upon factors including performance, data security, and number of
drives available. It is best to carefully consider the long-term role of the system
and plan the data storage strategy appropriately.Silicon Image has made the
creation of RAID sets very simple. They can be...

4. If manual configuration is selected, the chunk size of Striped Sets can be
selected.
5. If auto configuration is selected, BIOS will select RAID member drives
automatically.
6. Select RAID set size with    and    keys.
7. After the RAID set size is set, the message “Are You Sure?” will display before
completing the configuration. Answer “N” to abort the creation of the new RAID
set, or “Y” to proceed with the RAID set creation.
8. RAID sets can be created in both BIOS and in...
