WHY DO WE NEED RAID?
•
•
•
•
Redundant array of independent disk
RAID employs the technique of striping
Allow overlapped disk I/O across drives
To access information from several disks
at the same time
Levels of fault tolerance:
• Level 1
• Level 2
• Level 3 -also called duplicating the server
- One or more disk putting together
-concatenation of several hard disk
-RAID array drive
Levels of RAID
•RAID 0
•RAID 1
•RAID 4
•RAID 5
•RAID 10
RAID 0
Data blocks are split based on stripe size
RAID 1
• When one hard disk fails , all data is
immediately available
RAID 1 cont.
Disk duplexing
RAID 4
The controller calculates the parity bit, which is
stored in a separate hard disk
RAID 5
RAID 5 is similar to RAID 4. it delivers a balanced
throughput.
RAID 10
Combination of RAID 0 and 1.
Requirements
• SCSI hard drives
• RAID Controller board
• RAID driver
Installation procedure
Pre Installation:
1. boot the server from the RAID software
CDROM
2. Create a system disk for the OS
3. Turn off the sever
4. Disconnect the server from power
5. Remove the server cover
Installation procedure cont.
Zero-channel RAID controller board:
Replace the riser board, with the RAID controller
board in it
Power on the server and press <Ctrl> + <G>
Select the host drive type
Set the bios boot order:
Set up the following boot order:
Removable Devices
ATAPI CD-ROM Drive
Hard Drive
Intel (R) Boot Agent
RAS
What is RAS?
•RAS= Remote Access Server
•The ability to get access to a
computer or a network from a remote
distance
RAS Installation

Cont.
• Install NetBEUI protocol
