Release Note
This document has been modified from the original Nvidia Media Shield User’s Guide.
Some of the Nvidia screen captures may be different than your system.
Please Note: In order to access the RAID utility, press F10 repeatedly once the boot
screen appears.
Press Ctrl-X to exit the RAID utility, it will automatically save any changes.
There is not an option to exit without saving changes.
Windows Vista sees the RAID as a single logical drive, but it does not “color code” it as
a RAID storage solution in Administrative Tools. The RAID logical drive is color coded
the same as a single physical drive.
The RAID utility does not auto-rebuild a defective or replacement RAID HDD. The
rebuild process must be initiated in the RAID utility. The rebuild process may take
several hours depending on the size of the drives.
Here are some additional RAID definitions that may prove useful when configuring the
RAID array.
Striping = RAID 0
Mirroring = RAID 1
Stripe Mirroring = RAID 0+1
RAID 5 = RAID 5
Spanning = JBOD

ABOUT NVIDIA RAID
NVIDIA brings Redundant Array of Independent Disks (RAID) technology—which is
used by the world’s leading businesses—to the common PC desktop. This technology
uses multiple drives to either increase total disk space or to offer data protection.
RAID techniques were first published in 1988 by a multivendor consortium—the RAID
Advisory Board. RAID techniques were divided into different categories or levels.
Originally, RAID levels focused on improving resiliency or data availability. As
additional RAID levels were defined, one was introduced for improving performance. For
all levels, RAID techniques optimize storage solutions by using multiple disks grouped
This chapter describes NVIDIA RAID in the following sections:
• “System Requirements” on page 2.
• “RAID Arrays” on page 3 describes the RAID levels supported by NVIDIA RAID.
• “NVIDIA RAID Features” on page 9 describes additional features offered by NVIDIA
RAID.

CHAPTER 1
About NVIDIA RAID
RAID Arrays
This section describes the following types of RAID arrays that MediaShield supports:
• RAID 0
many applications.
• RAID 1
RAID 1 defines techniques for mirroring data.
RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays.
1
• RAID 5
RAID 5 provides fault tolerance and better utilization of disk capacity.
• JBOD
JBOD provides a method for combining drives of different sizes into one large disk.
Note: Not all nForce platforms provide support for all the RAID levels listed.
1. RAID 5 is supported on select boards only. Please check with your motherboard manufacturer to deter-
mine whether RAID 5 is supported for the type and model of your motherboard.

CHAPTER 1
About NVIDIA RAID
RAID 0
How RAID 0 Works
In a RAID 0 array, the controller ʺstripesʺ data across multiple drives in the RAID
subsystem. RAID 0 breaks up a large file into smaller blocks and then performs disk reads
and writes across multiple drives in parallel. The size of each block is determined by the
stripe size parameter, which you set during the creation of the RAID 0 set. Performance of
applications running with a RAID 0 can vary greatly depending on the stripe size
configured when creating the array. The default stripe size is 64K, but 32K or 16K may be
more efficient if the application issues many smaller I/O operations. Some amount of trial
and error may be appropriate to find the optimum stripe size.
Figure 1.1 RAID 0 Array Diagram
RAID 0 is ideal for applications that require high bandwidth but do not require fault
tolerance. RAID 0 has the best performance and capacity of any RAID level, but the lowest
availability (no fault tolerance). If one drive fails, the entire array fails because part of the
data is missing with no way to recover it other than restoring from a backup.
Summary of Features and Benefits
• Benefits: Provides increased data throughput, especially for large files.
• Drawbacks: No fault tolerance—all data is lost if any drive in the array fails.
• Uses: Intended for non-critical data requiring high data throughput, or any
environment that does not require fault tolerance.
• Drives: Minimum: 1. Maximum: Up to 8, depending on the platform.
• Fault Tolerance: No.

CHAPTER 1
About NVIDIA RAID
RAID 1
How RAID 1 Works
In a RAID 1 array, every read and write is carried out in parallel across two disk drives.
The mirrored—or backup—copy of the data can reside on the same disk or on a second
redundant drive in the array. RAID 1 provides a hot-standby copy of data if the active
volume or drive is corrupted or becomes unavailable due to a hardware failure. RAID 1
techniques can be applied for high-availability solutions, or as a form of automatic backup
that eliminates tedious manual backups to more expensive and less reliable media.
Figure 1.2 RAID 1 Array Diagram
RAID 1 provides complete data redundancy, but at the cost of doubling the required data
storage capacity, resulting in 50% capacity utilization. Performance is roughly the same as
for a single drive, although in some instances the dual write may be somewhat slower.
Summary of Features and Benefits
• Benefits: Provides 100% data redundancy. Should one drive fail, the controller
switches to the other drive.
• Drawbacks: Requires two drives for the storage space of one drive. Performance is
impaired during drive rebuilds.
• Uses: RAID 1 is ideal for small databases or any other application that requires fault
tolerance and minimal capacity.
• Drives: Minimum, 2. Maximum, 2.
• Fault Tolerance: Yes

CHAPTER 1
About NVIDIA RAID
RAID 0+1
How RAID 0+1 Works
RAID 0 drives can be mirrored using RAID 1 techniques, resulting in a RAID 0+1 solution
for improved performance plus resiliency.
Figure 1.3 RAID 0+1 Array Diagram
The controller combines the performance of data striping (RAID 0) and the fault tolerance
of disk mirroring (RAID 1). Data is striped across multiple drives and duplicated on
another set of drives.
Summary of Features and Benefits
• Benefits: Optimizes for both fault tolerance and performance, allowing for automatic
redundancy. May be simultaneously used with other RAID levels in an array, and
allows for spare disks.
• Drawbacks: Requires twice the available disk space for data redundancy, the same as
RAID level 1.
• Drives: Minimum: 4. Maximum: 6 or 8, depending on the platform.
• Fault Tolerance: Yes

CHAPTER 1
About NVIDIA RAID
RAID 5
How RAID 5 Works
RAID 5 stripes both data and parity information across three or more drives. It writes data
and parity blocks across all the drives in the array. Fault tolerance is maintained by
ensuring that the parity information for any given block of data is placed on a different
drive from those used to store the data itself.
Figure 1.4 RAID 5 Array Diagram
Summary of Features and Benefits
• Benefits: An ideal combination of good performance, good fault tolerance, and high
capacity and storage efficiency.
• Drawbacks: Individual block data transfer rate same as a single disk. Write
performance can be CPU intensive.
• Uses: RAID 5 is recommended for transaction processing and general purpose service.
• Drives: Minimum, 3
• Fault Tolerance: Yes

CHAPTER 1
About NVIDIA RAID
JBOD
How JBOD Works
JBOD stands for “Just a Bunch of Disks”. Each drive is accessed as if it were on a standard
SCSI host bus adapter. This is useful when a single drive configuration is needed, but it
offers no speed improvement or fault tolerance.
Figure 1.5 JBOD Array Diagram
Summary of Features and Benefits
• Benefits: JBOD provides the ability to combine odd size drives using all of the capacity
of the drives.
• Drawbacks: No additional fault tolerance or performance relative to individual disks.
• Uses: JBOD works best if you have odd sized drives and you want to combine them to
make one big drive.
• Fault Tolerance: No

In Figure 2.9, 1.0. means the hard drive is attached to Adapter 1, Channel 0.
The location, disk model and capacity fields should allow you to identify disks. It may be
useful to try attaching a SATA hard drive to the ports provided with your platform and
determine which location IDs are associated with SATA ports on your motherboard.
Using the Define a New Array Screen
If necessary, press the tab key to move from field to field until the appropriate field is
highlighted.
• Selecting the RAID Mode
By default, this is set to Mirroring. To change to a different RAID mode, press the down
arrow key until the mode that you want appears in the RAID Mode box—either
Mirroring, Striping, Spanning, Stripe Mirroring or RAID 5.
Note: Not all RAID levels are supported on all platforms.
• Selecting the Striping Block Size
Striping block size is given in kilobytes, and affects how data is arranged on the disk. It
is recommended to leave this value at the default Optimal, which is 64KB, but the
values can be between 4 KB and 128 KB (4, 8, 16, 32, 64, and 128 KB)
