Manual IB-NAS4220-B
Introduction
What is NAS?
NAS is short for “Network attached Storage”, which is used to name a specialized device
that offers mass storage towards a data network. SOHO NAS like the ICY BOX IB-
NAS4220-B are small devices that simply share data from HDDs to an Ethernet. There
are many approaches; some are using custom shaped methods in offering the storage
space to the network participants. This approach needs special software to be installed
on the network clients and in most cases is limited to one particular operating system.
The ICY BOX IB-NAS4220-B has chosen to offer the HDD space in the way common
operating systems are expecting it. This means it uses the same principles (protocols) to
offer HDD-Storage as common file servers are doing it but with less noise, lower power
consumption and in a much simpler way. The main advantage is that, that special
software is unnecessary to access the storage provided, whilst maintaining the maximum
security features, as already offered within the operation system, such as user and group
based access control.
Samba (Windows)
Network
The samba server implemented in the ICY BOX IB-NAS4220-B offers storage in a way
regular Windows shares are doing it (commonly known as SMB or CIFS protocol). Even
operating systems like MAC OS and Linux are capable of using this kind of network
storage access. It provides a maximum of security by offering the opportunity to limit the
access on users or groups.

Manual IB-NAS4220-B
FTP
The FTP protocol is one of the oldest ways for file transfer in the internet. It is fast and
could easily be used to access the HDD even via the internet. A huge set of different
software clients exists even for exotic operating systems using this simple but fast
protocol. Most internet access routers used in small offices and at home offer a
mechanism called port forwarding (virtual server, etc.) which could be easily used to
expose the ICY BOX IB-NAS4220-B’s storage to the internet. The FTP protocol offers
access control based on user and groups.
NFS
In the Unix world the NFS protocol is common to share disk space via network. This
protocol could be used to mount natively network storage to all kinds of Unix operating
systems like Linux, Solaris, etc. The NFS protocol is fast but does not provide a User or
Group based access control server sided. Access control is limited to the definition of
singular or a set of IP-Addresses (host addresses).
More than a NAS
But the IB-NAS4220-B is more. You can print via Network or if you want to access to
your music, pictures or video files by using your network at home the UPnP-AV protocol
offers a communication mechanism for your network media player to access all media
files on the IB-NAS4220.

You can attach your printer via USB to your IB-NAS4220-B and use it with several other
PCs at the same time.

The included Twonky Media Server (30 days trial version) adapts this standard to as
many players as possible. The Twonky Media Server has been updated several times a

Manual IB-NAS4220-B
year so far to ensure compatibility to all new players. Therefore we have chosen to not
implement this software fix in the firmware of the IB-NAS4200-B but to give the user to
easily upgrade it when a new version is released. A permanent license can be purchased
from the Website of Twonky Media by following a link from the user interface of Twonky
Media.
Bonjour and iTunes Support
Network
The IB-NAS4220 is able to assign its services via Bonjour, so that MAC computer can
easily be connected to the server functions of the IB-NAS4220-B. Due to the iTunes
support, multimedia files can be accessed via iTunes from anywhere in the network.

Manual IB-NAS4220-B
BitTorrent protocol Support
The IB-NAS4220-B has an integrated BitTorrent protocol client. So you can download
data via the peer to peer Network without a running PC. The IB-NAS4220-B consumes
much less electricity compared to a conventional PC. This protects the environment and
saves money.
What is RAID?
RAID is short for “Random Array of Inexpensive Disks”. It names a way of using several
hard disks intelligently together, in order to improve security or speed or to combine
their disk space. RAID is divided in levels. These levels, designated by a number, are
indicating each a certain strategy to combine disk space. Each strategy has different
advantages for the user. The IB-NAS 4220-B offers the following RAID levels:
RAID 0 (Stripe Set)
RAID 0 writes data block wise alternating on the two disks. So two data blocks can be
written at the same time, which enhances speed. The disk space of the combined volume
is twice the smaller disk size. If one drive fails, all data is lost. In reality, this level grants

no speed increase on the IB-NAS4220-B because other limitation factors are responsible
for the network performance than the drive access.
RAID 1 (Mirroring)

Disc 2
Disc 1
In RAID 1 mode all data is written identically on both discs. So if one disc fails the other
contains all data again. This provides security against the failure of one disk at the cost
of the bigger disks space.
Attention: If you choose RAID 1, please mind, that it is not a good strategy
to use two hard discs of the same type and from the same
product line. If the machine which produced the hard discs was defect,
it is very likely that all hard discs produced by that machine are defect.
If both discs fail, all data will be lost, because RAID 1 does not help
against the simultaneous failure of both discs.

To be exact Spann is not a real RAID mode, but could be seen as one. In Spann Mode,
the space of the second disc is simply appended to the first disc. So the space of the two

Manual IB-NAS4220-B
disks are added to one big disk. Because RAID 0 does not offer a real speed increase
Spann should be preferred.
JBOD
JBOD is short for “Just a Bunch Of Disks”. Like Spann it is not really a RAID mode. This
means that both discs are integrated as separate hard drives with its own content,
independent from each other.
