1.3 RAID Concepts

he 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. Five

types of array architectures, RAID 1 through RAID 5, were originally defined; each provides disk faulttolerance with different compromises in features and performance. In addition to these five redundant array architectures, it has become popular to refer to a non-redundant array of disk drives as a RAID 0 arrays.

Disk Striping

Fundamental to RAID technology is striping. This is a method of combining multiple drives into one logical storage unit. Striping partitions the storage space of each drive into stripes, which can be as small as one sector (512 bytes) or as large as several megabytes. These stripes are then interleaved in a rotating sequence, so that the combined space is composed alternately of stripes from each drive. The specific type of operating environment determines whether large or small stripes should be used.

Most operating systems today support concurrent disk I/O operations across multiple drives. However, in order to maximize throughput for the disk subsystem, the I/O load must be balanced across all the drives so that each drive can be kept busy as much as possible. In a multiple drive system without striping, the disk I/O load is never perfectly balanced. Some drives will contain data files that are frequently accessed and some drives will rarely be accessed.

By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives. This keeps all drives in the array busy during heavy load situations. This situation allows all drives to work concurrently on different I/O operations, and thus maximize the number of simultaneous I/O operations that can be performed by the array.

Insta

llation and Configuration Manual

Definition of RAID Levels

RAID 0 is typically defined as a group of

striped disk drives without parity or data redundancy. RAID 0 arrays can be configured with large stripes for multi-user environments or small stripes for single-user systems that access long sequential records. RAID 0 arrays deliver the best data storage efficiency and performance of any array type. The disadvantage is that if one drive in a RAID 0 array fails, the entire array fails.

RAID 1, also known as disk mirroring, is simply a pair of disk drives that store duplicate data but appear to the computer as a single drive. Although striping is not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a single large array consisting of pairs of mirrored drives. All writes must go to both drives of a mirrored pair so that the information on the drives is kept identical. However, each individual drive can perform simultaneous, independent read operations. Mirroring thus doubles the read performance

of a single non-mirrored drive and while the write performance is unchanged. RAID 1 delivers the best performance of any redundant array type. In addition, there is less performance degradation during drive failure than in RAID 5 arrays.

Dual-level RAID achieves a balance between the increased data availability inherent in RAID 1 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 10.

RAID 3 sector-stripes data across groups of

drives, but one drive in the group is dedicated

to storing parity information. RAID 3 relies on

the embedded ECC in each sector for error

detection. In the case of drive failure, data

recovery is accomplished by calculating the

exclusive OR (XOR) of the information

recorded on the remaining drives. Records

typically span all drives, which optimizes the

disk transfer rate. Because each I/O request

accesses every drive in the array, RAID 3

arrays can satisfy only one I/O request at a

time. RAID 3 delivers the best performance

SATA II-to-SATA II Internal RAID Subsystem

Ins

tallation and Configuration Manual

for single-user, single-tasking environments with long records. Synchronized-spindle drives are required for RAID 3 arrays in order to avoid performance degradation with short records. RAID 5 arrays with small stripes can yield similar performance to RAID 3 arrays.

Under

RAID 5 parity information

is distributed across all the drives. Since there is no dedicated parity drive, all drives contain data and read operations can be overlapped on every drive in the array. Write operations will typically access one data drive and one parity drive. However,

because different records store their parity on different drives, write operations can usually be overlapped.

RAID Management

The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below.

RAID Level Description Min. # of Drives

Block striping is provided and yields higher performance than with individual drives. There is no redundancy.

Drives are paired and mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant.

LARGE

Large is similar to RAID 0 in that it combines the capacity of all member drives (based on smallest drive capacity). The data is written linearly from first disk drive. When first disk drive becomes full, the next disk drive is used. Large can have 2 or more disk drives. There is no data redundancy.

CLONE

Clone provides multiple copies of data in a disk drive. Clone can have 2 or more disk drives.

Data is striped across several physical drives. Parity protection is used for data redundancy.

Combination of RAID levels 1 and 0. This level provides striping and redundancy through mirroring.

Chapter 2 Getting Started

This section describes the physical locations of the hard drives supported by the subsystem and give instructions on installing a hard drive. The subsystem supports hot-swapping allowing you to install or replace a hard drive while the subsystem is running.

This also discusses on how to power-on the subsystem in preparation for operation.

2.1 Installing Hard Drives

a. Push the tray latch to release a disk tray.

b. Then pull out an empty disk tray.

c. Place the hard drive in the disk tray. Make sure the holes of the disk tray align

with the holes of the hard drive.

d. Install the mounting screws on the bottom part to secure the drive in the disk

tray.

e. Slide the tray into a slot until it reaches a full stop.

f. Press the lever in until you hear the latch click into place.

2.2 Preparing the RAID Subsystem

Here are the steps to prepare the RAID subsystem for use.

1. Shutdown the host system.

2. Install the Internal RAID Box into the host system and secure it by using screws on the sides.

3. Connect the SATA cable from RAID subsystem to the SATA port on the host system.

4. Connect two 4-pin power connectors to the two power sockets.

5. Power on the host system.

Chapter 3 Configuration Utility

The subsystem has a setup configuration utility containing important information about the configuration as well as settings for various optional functions in the subsystem. This chapter explains how to use and make changes to the setup utility.

Configuration Method

The RAID subsystem can be configured using the Application Program provided with the subsystem. There are three versions: Microsoft Windows version, Linux version, and Mac OS version.

IMPORTANT: The RAID subsystem must be connected to the Host system in order to configure the RAID subsystem. If the RAID subsystem is not connected to the Host system, the Application Program will show “No disks or RAID!”

NOTE: At least disk drive must be inserted in the RAID subsystem. If there is no disk drive in the RAID subsystem, the Application Program will show “No disks or RAID!”
