Configuring arrays

Configure the physical disk drives in arrays. An array can consist of one
to four physical disk drives, depending on the RAID level. A RAID 0
array can consist of one to four physical drives, while a RAID 1 array
consists of two.

Configuration 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.

Assigning RAID levels

Only one RAID level can be assigned to each array. The table below
displays the drives required per RAID level.
