The preceding table shows how data is distributed for RAID 5. As you can see, each stripe has one block assigned to
track parity data. Parity data can be used to reconstruct the data on that stripe if one of the disks should fail. RAID 5
distributes parity information equally among all disk drives to equalize data I/O and achieve better overall
performance.
Setting Up the Arrays
To set up an array you need to define an array, set its parameters, and then initialize the array.
Define an Array
RAID arrays are defined using the Configuration Wizard. To define a RAID 5 array:
1. On the NetRAID Assistant’s menu bar click Configuration, then Wizard.
2. Select Custom in the dialog box and click Next.
The Configuration Wizard displays its Array Definition window.
