Chapter 1 Getting to Know Your NSA
Media Server User’s Guide
18
Above is the NSA in a home network. Users back up and share data on the NSA. The media player 
plays the NSA’s media files on the TV. A USB hard drive provides extra storage space and files are 
copied directly from the USB mass storage device to the NSA.
Place the NSA behind a firewall and/or IDP (Intrusion Detection and Prevention) device to protect it 
from attacks from the Internet. 
Refer to the Quick Start Guide for hardware connections and how to install and remove hard drives 
from the disk trays. 
Note: Turn off and disconnect the NSA before you install or remove the internal hard disk 
or disks.  
1.1.1  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 (
). Any hard disk connected to 
the USB port(s) is considered an external or USB volume.
1.1.2  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 
 for thStorage screen 
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 
 for more information on these storage methods.
