Unconfigured capacity
1. To create a new array from unconfigured capacity select the first option from Figure 8-43,
and click Next.The options for Free capacity will be grayed out.
2. Decide whether to select the drives automatically or manually. First we will choose
Automatic (Figure 8-44). Click Next.
Note: We always recommend you to use this Automatic wizard. This usually ensures the
most optimal balance between capacity, performance and redundancy. A manual
configuration will typically not have the most optimal settings.

1. Select the RAID level that you want for the array. The wizard will propose some
configurations depending on the RAID level chosen (Figure 8-45). Each configuration
indicates whether it offers enclosure loss protection or not. Enclosure loss protection is
when all array members are in different DS3000 and EXP3000 enclosures. We
recommend choosing a configuration with enclosure loss protection because it provides
higher availability.
You can choose between RAID 0, 1, 3, or 5 - if you pick RAID 1 and select four or more
drives, then RAID 10 (striping and mirroring) will be automically used on the array.
