What Makes QNAP NAS Different?
Embedded Linux
The embedded Linux kernel - developed in-house by QNAP’s
team of dedicated software engineers - on QNAP’s NAS solutions
provides an extremely stable and efcient platform. QNAP’s
proprietary NASWare OS is stored on ash disks rather than hard
drives, thus preventing virus infection or HDD damage to the system
itself. Even in the worst case of all hard drives failing simultaneously,
the NASWare OS will work as usual and send out warning
messages allowing the administrator the opportunity to minimize the
damage.
Cross Platform
All of QNAP’s storage products support different network le
protocols, so whether the users are working on a Windows,
Mac, Unix/Linux or Novell Netware OS environment or indeed
a combination thereof - the same data storage platform can be
shared.
Remote Data Access
Wherever the user is over the world, QNAP’s NAS can be accessed
through either web browser (HTTP) or FTP client software (FTP).
This offers the user the opportunity to administrate or even access
les and data remotely.
Hot-swappable Hard Disks & Data Auto-rebuild
Under the disk conguration of RAID 5 or RAID 1, users can replace
a new hard disk in the event that one should fail, without shutting
down the system (NAS-4000P or above). NASWare OS will then
start rebuilding the data back to the new hard disk automatically.
Hot-swappable & Redundant Power Protection
QNAP also includes in some of its range industrial grade hot-
swappable and redundant power supplies, which keep the system
running normally should any power supply fail.
RAID Level Disk Congurations + Hot Spare
Multiple disk congurations, including JBOD, RAID 0, 1, 5 and single
disk, offer the user the most complete options for data protection.
Under RAID 5 conguration, QNAP also provides another option -
Hot Spare: In the event of a hard drive failure, the system will start
rebuilding data on to the hot spare disk without needing to rst
replace the faulty drive.
Data Backup & Remote Replication
Combining backup software and NAS, users can easily backup
all or part of their critical data and/or les to the NAS server, and
QNAP also offers some models with the option of backing up data
from one QNAP NAS server to another or even to a tape drive. The
user interface is simple, clear and user-friendly. The backup source
can be local or remote les, whereas backup destinations can be
any number of NAS servers. Furthermore, backup jobs can be
scheduled for multitasking, and can be done within the intranet or
through the Internet.
LCD Display
All of QNAP NAS devices are equipped with an LCD display,
allowing the user to immediately see the status, IP address and
various other important pieces of information.
Router & Firewall
QNAP has developed a series of router storages combine NAS with
a Cable/DSL router which the user then connects up to the modem.
Featured with routing tables, virtual servers, DMZ and NAT, these
units offer true multi-functionality, whilst allowing multiple users
simultaneous access to the Internet, all with rewall protection.
Built-in DNS & DDNS Support
QNAP’s family of storage routers is equipped with a DNS server,
which simplies network and domain administration. With dynamic
DNS (DDNS) support, users can also own a unique domain by a
low-cost dynamic IP.
Web Page Management
All upgrades and administration can be completed simply via a
user-friendly web browser, either locally or remotely.
User Quota
The administrator has the authority to set up user’s storage limit
or quota. Thus power users who require larger amounts of data
storage space can be allocated additional capacity.
SNMP Management & E-mail Warning
SNMP management and E-mail warning provide updated system
status and real-time monitoring to keep the administrator informed
at all times as to what is happening in the unit.
WINS Server
This function maps Windows computer names to IP addresses,
building a dynamic database. Not only does it increase speed
for computer name resolutions, but it also effectively lessens the
network trafc load.
Flexible OS
NASWare is developed by QNAP’s dedicated team of software
engineers in-house, and is based on open-sourced Linux. The
exibility offered by the Linux-based kernel makes it easier to keep
NASWare updated with advanced or customized functions.
Backup/Restore User’s Setting
User’s setting can be easily backup and stored. When a new NAS
needs to be set up or if the original system is damaged, user ID’s,
passwords and other settings can be restored in very short period.
System Upgrade
Updated versions of QNAP’s NASWare OS (rmware) can be
downloaded from http://www.nasgenie.com, and free upgrade
service is available.
Journaling File System
Not only can the Journaling File System ensure the consistency but
it also reduces the time to boot up/shut down. Should the system
experience abnormal shutdowns or bootups, it can additionally help
the system reboot itself and return to normal operation.
Some features only available on certain models.
