Configuring Arrays
Organize the physical disk drives in arrays after the drives are connected to IDE software RAID. And array can consist of one to four physical disk drives, depending on the RAID level.
Configuration Strategies
The most important factors in RAID array configuration are drive availability (fault tolerance), and drive performance.
Maximizing Drive Availability - You can maximize the drive availability by increasing fault tolerance. Use RAID 1 or mirror configuration to maximize availability.
Maximizing Drive Performance - You can optimize drive performance by using striping. Select RAID 0 or striping to configure an array for optimal performance.
Performance and Availability - You can achieve both drive performance and availability. Select RAID 10 for this configuration. You will need four drives to configure RAID 10.
Assigning RAID Levels
Only one RAID level can be assigned to each array. The drives required per RAID level is
RAID | Minimum Number of Drives | Maximum Number of Drives |
Level |

0 | One | Four |
|

1 | Two | Two |
