1. RAID and RAS CIS 485 SAU SUJA SOLOMON TIFFANY STACIE

2. 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

3. 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

4. Levels of RAID RAID 0 RAID 1 RAID 4 RAID 5 RAID 10

5. RAID 0 Data blocks are split based on stripe size

6. RAID 1 When one hard disk fails, all data is immediately available

7. RAID 1 cont. Disk Duplexing

8. RAID 4 The controller calculates the parity bit, which is stored in a separate hard disk

9. RAID 5 RAID 5 is similar to RAID 4. it delivers a balanced throughput.

10. RAID 10 Combination of RAID 0 and 1.

11. Requirements SCSI hard drives RAID Controller board RAID driver

12. 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

13. Installation procedure cont. Zero-channel RAID controller board:

14. Replace the riser board, with the RAID controller board in it Power on the server and press +

17. Select the host drive type

18. Set the bios boot order: Set up the following boot order: Removable Devices ATAPI CD-ROM Drive Hard Drive Intel (R) Boot Agent

19. RAS What is RAS? RAS= Remote Access Server The ability to get access to a computer or a network from a remote distance
