3.9.1 Connecting External USB Hard Drives

The easiest way to increase the NSA's storage capacity is to connect an external USB hard
drive. External USB hard drives are great for providing storage capacity for scheduled
backups and snapshots of internal volumes. (External volumes can be the destination for a
scheduled backup or snapshot, but only an internal volume can be the source.) Use the
following procedure.
1 Connect the external USB hard drive to USB1 or USB2 on the NSA's front panel.

2 Click Storage > External Volumes and make sure the USB drive displays with a
healthy status.

The NSA automatically creates volumes for the USB drive. You just need to configure sharing
settings (Chapter 8 on page

3.9.2 Adding an Internal Hard Drive to an Existing Disk Array

If you do not already have four disks installed, you can install more. You can add a new disk to
an existing JBOD array or three-disk RAID 5 array. When you add a new disk to an existing
array, you do not have to create new volumes and sharing settings.
For optimal performance and RAID storage capacity, use hard drives of the same speed and
capacity.
