1.5.3 ESD precautions
In order to avoid damage to uNAS/tNAS, please ensure you are grounded before opening the system or
the ESD package that contains uNAS/tNAS. Using grounding straps or mats is the best way to ensure this
safety. If you don’t have grounding equipment handy, please make sure you are grounded before working
with uNAS/tNAS, for instance, by touching a heater.
• Avoid unnecessary touching of the components inside the PC,
• Please touch uNAS/tNAS only on the edges.
2 Features
2.1 What is NAS?
NAS ( Network Attached Storage ) solutions are defined as storage systems that are directly hooked up to a
network infrastructure. Also, they operate independently and do not have to be connected to a server via a
controller or host adapter. The term “storage” here generally refers to all systems that either provide data
storage or actually store or organize data. Currently, data storage is the most common and most
widespread type of NAS systems.
NAS solutions are based on a separate operating system (and often also on special hardware), which
operates independently from the servers on a network. Typically, this operating system is software that is
optimized for providing data (file server). NAS solutions allow users to add additional storage to existing
networks quickly, easily, and cost-efficiently.
2.2 Description of the functions
To begin working with uNAS/tNAS, all you need to do is assign an IP address to the NAS server – either
automatically through an existing DHCP server or by assigning it manually. All other settings are handled
via a web front-end which can be easily accessed through the IP address of uNAS/tNAS using the
encrypted https protocol.
uNAS/tNAS allows users to create so-called shares (i.e., resources within a network that numerous users
or user groups have certain access too). The access rights to the shares are controlled through the user
and user group settings.
Within a few minutes, you will have up to several hundred gigabytes available on your network – without
much effort and any downtime.
2.3 RAID types
This manual is not intended to explain the raid function in detail. But we want to provide you with an
overview of common RAID types so that you can make an informed decision on which type to choose.
Depending on whom you ask, RAID means either Redundant Array of Independent Disks or Redundant
Array of Inexpensive Disks. Both are correct. In essence, you combine the capacity, speed and security of
several disks into one.
RAID 0 forms one large hard disk by concatenating stripes from each member drive.
