Chapter 1 Getting to Know Your NSA

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.

Note: See Chapter 20 on page 345 for a more detailed list of NSA features.

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 7.3 on page 155). 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 7.3 on page 155 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 7.1.1 on page 151 for more information on these storage methods.
