Smartphone App; Hard Disks For 2-Bay Models; Hard Disks For 1-Bay Models - ZyXEL Communications NSA325 User Manual

Chapter 1 Getting to Know Your NSA
Place the NSA behind a firewall and/or IDP (Intrusion Detection and Prevention) device to protect it
from attacks from the Internet.
Note: See Chapter 21 on page 365
Refer to the Quick Start Guide for hardware connections and how to install hard drives.
Note: Turn off and disconnect the NSA before you install or remove the internal hard disk
or disks.
• The NSA325 is a 2-bay model.
• At the time of writing no 1-bay models support the firmware version documented in this User's
Guide.

1.1.1 Smartphone App

Use ZyXEL's zMedia app to play files and manage the NSA from your iOS version 3 or later device or
Android version 2.1 or later smartphone.

1.1.2 Hard Disks for 2-Bay Models

The 2-bay NSA models have two internal hard disk bays. Install one or two SATA (Serial Advanced
Technology Attachment) hard disks. Note that both SATA hard disks are treated as internal or SATA
volumes in the Storage > Volume screen
the USB port(s) is considered an external or USB volume.

1.1.3 Hard Disks for 1-Bay Models

The 1-bay NSA models have one internal hard disk bay and one external SATA (eSATA) port. This
allows you to connect one internal SATA (Serial Advanced Technology Attachment) hard disk and
one eSATA hard disk (optional).
Initializing the internal hard disk configures it as a JBOD volume by default. JBOD stands for Just a
Bunch Of Disk and in this storage method, all disk space is used for your data - none is used for
backup. If you are not using an eSATA hard disk, JBOD is the only storage method you can use.
If you attach an eSATA (external SATA) hard disk, you can create a RAID 1 volume. RAID 1 allows
data recovery in case your hard disk fails. To create a RAID 1 volume on the NSA, you must delete
the JBOD volume created by the firmware. Refer to
where you can create the RAID 1 volume.
The eSATA hard disk can also be configured as a JBOD or a PC Compatible Volume. See
8.1.1 on page 157
