Section 1 - Product Overview
The D-Link DNS-321 2-Bay Network Storage Enclosure shares your documents, photos, music, and videos across
the network and on the Internet (via FTP server) so family members, friends, or employees can access them. This
enclosure, which can hold two 3.5” SATA hard drives of any capacity1, creates a central network point for backing up
valuable files. The built-in RAID 12mirroring technology protects these files from drive failure. Other options such as
Standard, JBOD, and RAID 0 are also available.
The DNS-321 shares files over the Internet via the built-in FTP server3. Users and groups can be created and assigned
to folders with either read or read/write permissions. Quotas can be set per user or group to restrict space usage.
In addition, the DNS-321 can be used to stream photos, music, and videos to UPnP AV compatible network media
players4.
The included CD contains D-Link’s Easy Search Utility. This utility allows you to locate the DNS-321 on the network
and map drives to your computer. Backup software is also included on the CD. This software allows you to backup your
files from a computer to the DNS-321 manually, by a schedule, or in real-time. Real-time backups are a great way to
safeguard against unfortunate accidents that may result in the loss of important files.
Combining ease of use with practical and high performance features, the DNS-321 is an organized solution for any
network. Free up drive space on computers and centralize data on your network with the DNS-321 2-Bay Network
Storage Enclosure!
