1.3 RAID Concepts

The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple

inexpensive disk drives into an array of disk drives to obtain performance, capacity and

reliability that exceeds that of a single large drive. The array of drives appears to the

host computer as a single logical drive.

The RAID subsystem provides data striping, mirroring, XOR calculation and data

verification. It supports RAID levels 0, 1, 3, 5, 10, LARGE and CLONE. All RAID levels’

capacity can exceed 2 Terabytes. The RAID subsystem behaves as a full 48-bit

addressing RAID drive and is 100% ATA compliance.

From (PC) host controller, each logical device (RAID volume) controlled by the RAID

system acts just the same as single regular hard disk although a RAID system generally

consists of more than one hard disk drives. Therefore, no extra BIOS, driver or software

is needed.

1.3.1 Definition of RAID Levels

Striping (RAID 0) for High Performance

Striping or RAID 0 is the segmentation of logically sequential

data, such as a single file, so that segment can be assigned to

multiple hard disks in a round-robin fashion and thus written

concurrently.

Advantage of RAID 0 is to achieve high performance by

accumulating each individual hard disk performance. However,

if any one hard disk gets defective, information stored in this

RAID 0 will become invalid.

The RAID subsystem will just make use of the same disk

space for each hard disk under RAID 0 condition. For example,

if a RAID 0 consists of 5 different size hard disks, the total

usable space of this RAID 0 will be [capacity of smallest size

hard disk] * [the number of hard disks in this RAID 0].

Mirror (RAID 1) for High Security

Mirror or RAID1 is the replication of data onto separate hard

disk in real time to ensure continuous availability. In a RAID 1

system with two hard disks, the data in one hard disk will be

exactly the same as the data in the other hard disk.

The RAID subsystem will also make use of same size disk

space in each hard disk in RAID 1. That is, the RAID controller

will write data to the same disk space in each hard disk. When

reading data, the RAID controller will read data from a

specified hard disk.

Failure in a hard disk will cause the RAID controller to enter

into degraded mode. The host controller can still read/write

data to the RAID without knowing any hard disk defect. Users

have to replace the hard disk then the RAID controller will

enter in on-line rebuild mode automatically.

Besides, if there is only partial defect in a hard disk, the RAID

controller will read data from the other healthy hard drive.

Stripe + Mirror (RAID 10) for High

Performance and High Security

RAID subsystem could be configured to

support Stripe and Mirror at the same

time, i.e. RAID 10. Take four hard

drives in RAID 10 as an example. Hard

drive 0 and hard drive 1 could act as

Mirror 1. Hard drive 2 and hard drive 3

act as Mirror 1 too. The RAID controller

then configures these two Mirrors as

Stripe.

At least two drives (either one in each

Mirror) can be allowed to fail without

any impact to RAID data access. If two

drives from the same Mirror are failed,

the RAID data is not accessible and

becomes invalid.

CLONE

Clone’s action is similar to RAID 1. However,

all of the hard disks will be the mirrors. For

example, in a four hard drives Clone

environment, data in each hard drive will be

the same. This mode is useful especially when

users would like to copy data from a hard

drive to several hard drives at the same time.

The number of allowed failed drives is the total

number of drives in the RAID minus one.

Concatenating (Large)

This mode is also named “Large”. In this mode,

the RAID controller will concatenate all of the hard

drives into a single hard drive with larger capacity.

For example, if three 500GB hard disks are

connected to the RAID subsystem in Large Mode,

user will get a single hard disk with capacity of

1,500GB.

If any one hard disk gets defective, information

stored in this LARGE RAID will become invalid.

Parity Protection (RAID 3 and RAID 5)

The XOR engine in the RAID controller

generates parity block. In RAID 3 mode,

parity block will be stored in the same hard

disk drive. In RAID 5 mode, parity block will

be spread over all of the different hard

drives.

The RAID controller will also make use of

the same size disk space in each hard disk

under RAID 3 / RAID 5 condition.

Failure in a hard disk will cause the RAID

controller to enter into degraded mode. Host

controller still could rear/write data thru the

RAID normally without knowing any defects.

Users have to replace the defective hard

disk. The RAID controller will then enter into

online-auto-rebuild mode automatically.
