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 (Section 8.3 on page 165). 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 Section 8.3 on page 165 for the Storage 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 Section
8.1.1 on page 161 for more information on these storage methods.
