Installing the Controller and Drives

Why build a RAID 5?

This array level is supported by your controller. It provides a
versatile combination of performance and redundancy on a
minimum of three drives. Because RAID 5 uses parity, it is the
safest, and most recoverable, of all RAID levels.

What if I prefer a different array level?

That’s no problem. Once you build your array and install your
operating system, you can change array levels (see

Array Level

Migration on page 1-8

) or expand the capacity of the array (see

Online Capacity Expansion on page 1-8

) to suit your needs.
