Your NSA has a single bay for a SATA (Serial Advanced Technology Attachment) hard disk. The
firmware installed during hard disk initialization (Chapter 3 on page 31) automatically creates a
JBOD volume on your SATA hard disk. JBOD is the default storage method if you are using a single
hard disk for your NSA.
This JBOD volume shows up in the Storage > Volume screen (Section 8.2 on page 162) as
follows.
When you attach an eSATA hard disk to your NSA, you can configure this volume as: 1) a backup to
your SATA hard disk (RAID 1); or 2) as a separate storage drive (either another JBOD or a PC
Compatible Volume).
5.7.1 Creating a RAID 1 Volume
This storage method allows recovery of data if your hard disk fails. To create a RAID 1 volume, you
must connect an eSATA hard disk to your NSA. There are two ways to create a RAID 1 volume:
• Click the Migrate button - This is a quick way to create a RAID 1 volume. Use this to
automatically synchronize data in the internal hard disk to the eSATA hard disk.
• Click the Create a SATA volume button - Use this if there are no existing volumes in your NSA.
5.7.2 Migrate Button
Do the following steps to create a RAID 1 volume.
1 Once you attach the eSATA hard disk to the NSA, the Storage > Volume screen shows the
Migrate button.
