Using Custom Conguration: RAID 5

RAID 5 uses disk striping at the block level and parity. In RAID 5, the parity

information is written to all drives. It is best suited for networks that perform a

lot of small input/output (I/O) transactions simultaneously. RAID 5 provides data

redundancy, high read rates, and good performance in most environments. It also

provides redundancy with lowest loss of capacity.

RAID 5 provides high data throughput. RAID 5 is useful for transaction processing

applications because each drive can read and write independently. If a drive fails,

the RAID controller uses the parity drive to recreate all missing information. You

can use RAID 5 for ofce automation and online customer service that require

fault tolerance. In addition, RAID 5 is good for any application that has high read

request rates but low write request rates.

When you select Custom Conguration and click Next, the Disk Group Denition

screen appears. You use this screen to select physical drives to create disk groups

(arrays).

1. Hold <Ctrl> while you select at least

three ready physical drives in the

Physical Drives window on the left.

2. Click Accept DG to move the

drives to a proposed disk group

conguration in the Disk Groups

window on the right, as shown in

the right gure.

If you need to undo the changes,

click the Back button.
