RAID Background
R
User's Manual 11
2 RAID Background
RAID (Redundant Array of Inexpensive Disks) was originally conceived at the University of
California at Berkeley in 1987 by David A. Patterson, Garth Gibson, and Randy H. Katz. The
focus of their research was to improve storage subsystem performance and reliability. As a result
of their findings, they proposed five levels of RAID (RAID 0 – RAID 5) to provide a balance of
performance and data protection. Each RAID level is designed for speed, data protection, or a
combination of both. Patterson, Gibson, and Katz published their findings in a document titled “A
Case for Redundant Arrays of Inexpensive Disks (RAID).” This document is archived at the
University of California, Berkeley:
http://sunsite.berkeley.edu/TechRepPages/CSD-87-391
RAID was designed to improve the way computers manage and access mass storage of data by
providing an independent and redundant system of disks. Instead of writing to one Single Large
Expensive Disk (SLED), RAID writes to multiple independent disks.

RAID 0 (Striping)
R
User's Manual 13
3 RAID 0 (Striping)
RAID 0 leverages the read/write capabilities of two or more hard drives working in unison to
maximize the storage performance of a computer system. Data in a RAID 0 array is arranged into
blocks that are interleaved among the disks so that reads and writes can be performed in parallel
(see below diagram). This technique, known as “striping”, is the fastest of all of the RAID levels,
especially for reading and writing large sequential files. Real world usage models where RAID 0
can be of particular benefit include loading large files into an image editing application such as
Adobe* Photoshop*, saving large movie files in a video editing application such as Adobe*
Premiere*, or creating CD or DVD images with a CD/DVD authoring package such as Roxio*
Easy CD Creator*.
The hard drives in a RAID 0 array are combined to form one volume which appears as a single
virtual drive to the operating system. For example, two 40 GB hard drives in a RAID 0 array will
appear as a single 80 GB hard drive to the operating system.
No redundancy information is stored in a RAID 0 array. This means that if one hard drive fails,
all data on both drives is lost. This lack of redundancy is also reflected by the RAID level 0,
which indicates no redundancy. RAID 0 is not recommended for use in servers or other
environments where data redundancy is a primary goal.
Figure 1. RAID 0
Minimum Disks: 2
Advantage: Highest transfer rates
Redundancy: None – if one disk fails all data will be lost
Application: Typically used in desktops and workstations for maximum performance for temporary
data and high I/O rate

RAID 1 (Mirroring)
R
User's Manual 15
4 RAID 1 (Mirroring)
A RAID 1 array contains two hard drives where the data between the two is mirrored in real time.
Since all of the data is duplicated, the operating system treats the usable space of a RAID 1 array
as the maximum size of one hard drive in the array. For example, two 40 GB hard drives in a
RAID 1 array will appear as a single 40 GB hard drive to the operating system.
The primary benefit of RAID 1 mirroring is that it provides good data reliability in the case of a
single disk failure. When one disk drive fails, all data is immediately available on the other
without any impact to the data integrity. In the case of a disk failure, the computer system will
remain fully operational to ensure maximum productivity.
The performance of a RAID 1 array is greater than that of a single drive since data can be read
from multiple disks simultaneously, although disk writes do not realize the same benefit as is the
case with RAID 0.
Figure 2. RAID 1
Minimum Disks: 2
Advantage: 100% redundancy of data. One disk may fail, but data will continue to be
accessible. A rebuild to a new disk is recommended to maintain data
redundancy.
Redundancy: Excellent - disk mirroring means that all data on one disk is duplicated on
another disk.
Application: Typically used for smaller systems where capacity of one disk is sufficient
and for any application(s) requiring very high availability.

RAID Migration Feature
R
User's Manual 17
5 RAID Migration Feature
The RAID migration feature in the Intel® Application Accelerator RAID Edition is an advanced
software technology that enables a properly configured PC, known as a “RAID Ready” system, to
be easily converted into a high-performance RAID 0 or RAID 1configuration by simply adding a
Serial ATA hard drive to the system and invoking the RAID migration process from within
Windows*.
The migration to a RAID 0 or RAID 1 configuration is performed without the traditional
requirements of an operating system re-install. All applications and data remain intact.
The migration process itself can take up to several hours depending on the size of the hard drives
being converted, but the system is still fully functional while the migration is being performed – it
is possible to conduct other activities such as surf the Web and/or run productivity applications
while the system is being migrated. The only limitation is that some disk intensive tasks may
experience slower performance during a RAID migration.
The RAID migration feature also features advanced safety algorithms to ensure that an interrupted
migration does not result in data loss or corruption. If the migration process is interrupted via a
power loss or system reset, the migration will resume from the point of it’s most recent progress
upon the next system reboot.

6 Intel Application Accelerator RAID
Edition
6.1 Description
The Intel Application Accelerator RAID Edition is the software package that enables high-
performance RAID 0 arrays and redundant RAID 1 arrays in Windows* XP and Windows 2000.
The Intel Application Accelerator RAID Edition contains the following key features:
• Serial ATA RAID core driver for Windows XP and Windows 2000
• Intel Application Accelerator RAID Edition utility
• Migration Feature
6.2 Do You Need the Intel Application Accelerator RAID
Edition?
The Intel Application Accelerator RAID Edition reduces the storage sub-system bottleneck,
enabling the processor and other system level hardware to be more productive and efficient. It is a
requirement in order for Intel® RAID Technology to work properly. It is not a requirement for
stand-alone Serial ATA hard drive(s) to work properly (e.g. not configured for RAID).
To use the Intel Application Accelerator RAID Edition, your system must meet ALL of the
following requirements:
• A supported Intel chipset
http://support.intel.com/support/chipsets/iaa_raid/suppchip.htm
• A supported operating system
http://support.intel.com/support/chipsets/iaa_raid/supported.htm
To take advantage of increased storage subsystem performance and overall system performance,
your system must meet the following requirement:
• A Serial ATA device (e.g. hard drive that supports Generation 1 transfers)
Warning: Serial ATA has specific requirements. Please refer to the Appendix C.3 for more information.
