RAID Configuration and Management RAID 1 (Mirror) RAID 1 is a RAID level that involves duplicating all data from one drive to a second drive (mirroring). RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity. You must have a minimum of two hard drives to support RAID 1. RAID 1+0 RAID 1+0 (also known as RAID 10) is a RAID level that provides both striping and mirroring capabilities. RAID 1+0 mirrors data from one drive to another and then stripes the data across a second set of drives. You must have four hard drives to support RAID 1+0 on the server. RAID 5 RAID 5 is not supported by the ProLiant ML330 Generation 3 server or the Integrated ATA RAID Configuration Utility. This RAID level stripes data and parity information across drives and requires a minimum of three hard drives. Spare The spare option in the utility assigns an extra, unused drive as a spare to be used in case of a drive failure. The spare drive will not be used during normal system operation, and provides no additional storage capacity. A pre-configured spare hard drive is brought into service only in the case of a RAID 1 failure. IMPORTANT: The spare option is applicable only in RAID 1 for the server. If a spare is not available, the failed drive must be replaced with a new drive so that the data on the failed drive can be rebuilt. The replacement drive capacity must be greater than or equal to the failed drive it replaces. 6-2 HP ProLiant ML330 Generation 3 Server Setup and Installation Guide

RAID Configuration and Management

RAID 1 (Mirror)

RAID 1 is a RAID level that involves duplicating all data from one drive to a second

drive (mirroring). RAID 1 provides complete data redundancy, but at the cost of

doubling the required data storage capacity. You must have a minimum of two hard

drives to support RAID 1.

RAID 1+0

RAID 1+0 (also known as RAID 10) is a RAID level that provides both striping and

mirroring capabilities. RAID 1+0 mirrors data from one drive to another and then

stripes the data across a second set of drives. You must have four hard drives to

support RAID 1+0 on the server.

RAID 5

RAID 5 is not supported by the ProLiant ML330 Generation 3 server or the

Integrated ATA RAID Configuration Utility. This RAID level stripes data and parity

information across drives and requires a minimum of three hard drives.

Spare

The spare option in the utility assigns an extra, unused drive as a spare to be used in

case of a drive failure. The spare drive will not be used during normal system

operation, and provides no additional storage capacity. A pre-configured spare hard

drive is brought into service only in the case of a RAID 1 failure.

IMPORTANT:

The spare option is applicable only in RAID 1 for the server. If a spare is not

available, the failed drive must be replaced with a new drive so that the data on the failed drive

can be rebuilt. The replacement drive capacity must be greater than or equal to the failed drive

it replaces.
