3.2Configuration Strategies

You have two choices when creating a RAID array.

Maximizing Fault Tolerance

You can maximize fault tolerance to protect against loss of data by using mirroring. Use mirror configuration (RAID 1) to attain this objective.

Maximizing Logical Drive Performance

You can maximize logical drive performance by using striping. Select striping configuration (RAID 0) to attain this objective.

RAID 10 combines both striping and mirroring to provide high data transfer rates and data redundancy.

3.3Assigning RAID Levels

Only one RAID level can be assigned to each array. Table 3.1 displays the drives required per RAID level.
