Why Embedded Linux
Compact in Size
Based on embedded Linux, QNAP’s NASWare was developed to
an extremely compact size - only about 9MB. Compared to other
operation systems, which are usually over 1GB and stored on the
hard drives, the Linux based OS offers both better performance
and stability. All QNAP NASWare can be stored on a 32MB  ash
ROM, ensuring that all Linux resources are ef ciently utilized, and
hardware overheads absolutely minimized.
Stability
When choosing a NAS device, stability is the most important
thing of all. Embedded Linux Technology provides a reliable and
exclusive storage platform, allowing NAS servers to conduct a
uniform performance under non-stop operations.
Performance
Under the devotion of QNAP’s R&D team, Embedded Linux has
been intelligently developed to a compact size to improve the
system performance without having to be accessed through hard
drives.
Flexibility
Embedded Linux can be customized according to customers
speci c requirements
DDNS (Dynamic Domain Name Service)
With DDNS, even without a  xed IP address and domain
name, users are able to build up a personal or company
website. Depending on region or territory, when using ADSL
or Cable Modem to connect to the Internet, the IP address
assigned by the ISP may be different every time. They are
able to automatically renew an dynamic IP address, allowing
authorized users on the Internet to easily access the NAS
storage server via an assigned dynamic domain name.

Why use DDNS (Dynamic Domain Name Service)?
Cost-effectiveness
1. No need to pay extra license fee
2. Free lifetime software downloads providing free downloads of
the most up-dated versions of NASWare.
System Security
Having the OS installed on the Flash ensures that the system
continues running even in the event of a hard drive failure, and
with warning messages sent to notify system administrators
through e-mails.
1. NAS will notify DDNS
Server of the renewed IP
address when NAS dynamic
IP changes
4. Once the remote
client receives the
dynamic mapping IP
address, it can access
the remote router NAS
3. DDNS Server will reply to the remote
client with the renewed IP address of roter
NAS
2. Whever the remote client enters the URL: A_product.dyndns.org
in the web browser, the message will be transferred to DDNS Server
looking for NAS current IP address
QNAP Router NAS
Only available on QNAP Router NAS
The bene t of storing OS and Data in
separate places:
Storing the OS and Data in different places reduces the risk
of system downtime due to hard drive failures, and improves
system performance. The use of OS on Flash greatly reduces
repetitive data access of hard drives on the same disk area,
extends the lifespan of hard drives and minimizes power
consumption. Therefore, Embedded Linux is able to offer
better performance and stability than other available OS.
How does DDNS work with QNAP Router NAS?
Vendor-A , adopting a dynamic IP address, applies for a dynamic
domain name _product.dyndns.org from the DDNS service
provider in order to provide product information, catalogues, and
image download services to its customers. With the regisered
DDNS information stored in QNAP Router NAS, all customers
will be able to connect to Http://A_product.dyndns.org// and
downloads the needed products information, catalogues, and
images via the Internet anytime and anywhere.
