3ware
®
9750 series RAID controllers, using software
and firmware version 10.0.
This guide assumes that you have already installed your 3ware RAID

The following conventions are used throughout this guide:
3BM refers to the 3ware BIOS Manager.
3DM and 3DM 2 both refer to the 3ware Disk Manager, version 2.
In the sections that describe using 3DM 2, current controller is used to
refer to the controller which is currently selected in the drop-down list.
Unit refers to one or more disks configured through 3ware to be treated by
the operating system as a single drive. Also known as an array. Array and
unit are used interchangeably throughout this manual.
Boldface is used for buttons, fields, and settings that appear on the screen.
Monospace font is used for code and to indicate things you type.
Screenshots
The screenshots in this documentation are examples only, and may not exactly
reflect the operating system and browser you are using. 3ware software works
on a number of different operating systems, including Mac OS X, Microsoft

Understanding RAID Concepts and Levels
www.lsi.com/channel/products 5
Understanding RAID Concepts and Levels
3ware RAID controllers use RAID (Redundant Array of Independent Disks)
to increase your storage system’s performance and provide fault tolerance
(protection against data loss).
This section organizes information about RAID concepts and configuration
levels into the following topics:
“RAID Concepts” on page 5
“Available RAID Configurations” on page 6
“Determining What RAID Level to Use” on page 11
RAID Concepts
The following concepts are important to understand when working with a
RAID controller:
Arrays and Units. In the storage industry, the term “array” is used to
describe two or more disk drives that appear to the operating system as a
single unit. When working with a 3ware RAID controller, “unit” is the
term used to refer to an array of disks that is configured and managed
through the 3ware software. Single-disk units can also be configured in
the 3ware software.
Mirroring. Mirrored arrays (RAID 1) write data to paired drives
simultaneously. If one drive fails, the data is preserved on the paired
drive. Mirroring provides data protection through redundancy. In
addition, mirroring using a 3ware RAID controller provides improved
performance because 3ware’s TwinStor® technology reads from both
drives simultaneously.
Striping. Striping across disks allows data to be written and accessed on
more than one drive, at the same time. Striping combines each drive’s
capacity into one large volume. Striped disk arrays (RAID 0) achieve
highest transfer rates and performance at the expense of fault tolerance.
Distributed Parity. Parity works in combination with striping on RAID 5,
RAID 6, and RAID 50. Parity information is written to each of the striped
drives, in rotation. Should a failure occur, the data on the failed drive can
be reconstructed from the data on the other drives.
Hot Swap. The process of exchanging a drive without having to shut
down the system. This is useful when you need to exchange a defective
drive in a redundant unit.
Array Roaming. The process of removing a unit from a controller and
putting it back later, either on the same controller, or a different one, and
having it recognized as a unit. The disks may be attached to different ports
than they were originally attached to, without harm to the data.
Introducing the LSI 3ware SATA+SAS RAID Controller Card
6 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0
Available RAID Configurations
RAID is a method of combining several hard drives into one unit. It can offer
fault tolerance and higher throughput levels than a single hard drive or group
of independent hard drives. LSI's 3ware controllers support RAID 0, 1, 5, 6,
10, 50, and Single Disk. The information below provides a more in-depth
explanation of the different RAID levels.
RAID 0
RAID 0 provides improved performance, but no fault tolerance. Since the
data is striped across more than one disk, RAID 0 disk arrays achieve high
transfer rates because they can read and write data on more than one drive
simultaneously. The stripe size is configurable during unit creation. RAID 0
requires a minimum of two drives.
When drives are configured in a striped disk array (see Figure 2), large files
are distributed across the multiple disks using RAID 0 techniques.
Striped disk arrays give exceptional performance, particularly for data
intensive applications such as video editing, computer-aided design and
geographical information systems.
RAID 0 arrays are not fault tolerant. The loss of any drive results in the loss of
all the data in that array, and can even cause a system hang, depending on
your operating system. RAID 0 arrays are not recommended for high
availability systems unless additional precautions are taken to prevent system
hangs and data loss.
Figure 2. RAID 0 Configuration Example
RAID 1
RAID 1 provides fault tolerance and a speed advantage over non-RAID disks.
RAID 1 is also known as a mirrored array. Mirroring is done on pairs of
drives. Mirrored disk arrays write the same data to two different drives using
RAID 1 algorithms (see Figure 3). This gives your system fault tolerance by
preserving the data on one drive if the other drive fails. Fault tolerance is a
basic requirement for critical systems like web and database servers.
3ware uses a patented technology, TwinStor
®
, on RAID 1 arrays for improved
performance during sequential read operations. With TwinStor technology,
Understanding RAID Concepts and Levels
www.lsi.com/channel/products 7
read performance is twice the speed of a single drive during sequential read
operation.
The adaptive algorithms in TwinStor technology boost performance by
distinguishing between random and sequential read requests. For the
sequential requests generated when accessing large files, both drives are used,
with the heads simultaneously reading alternating sections of the file. For the
smaller random transactions, the data is read from a single optimal drive head.
Figure 3. RAID 1 Configuration Example
RAID 5
RAID 5 provides performance, fault tolerance, high capacity, and storage
efficiency. It requires a minimum of three drives and combines striping data
with parity (exclusive OR) to restore data in case of a drive failure.
Performance and efficiency increase as the number of drives in a unit
increases.
Parity information is distributed across all of the drives in a unit rather than
being concentrated on a single disk (see Figure 4). This avoids throughput
loss due to contention for the parity drive.
RAID 5 is able to tolerate 1 drive failure in the unit.
Figure 4. RAID 5 Configuration Example
Introducing the LSI 3ware SATA+SAS RAID Controller Card
8 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0
RAID 6
RAID 6 provides greater redundancy and fault tolerance than RAID 5. It is
similar to RAID 5, but has two blocks of parity information (P+Q) distributed
across all the drives of a unit, instead of the single block of RAID 5.
Due to the two parities, a RAID 6 unit can tolerate two hard drives failing
simultaneously. This also means that a RAID 6 unit may be in two different
states at the same time. For example, one sub-unit can be degraded, while
another may be rebuilding, or one sub-unit may be initializing, while another
is verifying.
The 3ware implementation of RAID 6 requires a minimum of five drives.
Performance and storage efficiency also increase as the number of drives
increase.
Figure 5. RAID 6 Configuration Example
RAID 10
RAID 10 is a combination of striped and mirrored arrays for fault tolerance
and high performance.
When drives are configured as a striped mirrored array, the disks are
configured using both RAID 0 and RAID 1 techniques, thus the name RAID
10 (see Figure 6). A minimum of four drives are required to use this
technique. The first two drives are mirrored as a fault tolerant array using
RAID 1. The third and fourth drives are mirrored as a second fault tolerant
array using RAID 1. The two mirrored arrays are then grouped as a striped
