  QNAP TS-439U-RP/ SP is the new generation 1U rackmount model
of the worldwide award-winning Turbo NAS Series, providing superior performance for
massive data sharing, powerful all-in-one business server features, advanced RAID data
protection, built-in iSCSI target service, AES 256-bit volume-based encryption, and
rock-solid hot-swappable hard drive design for business. The newly-designed HDD tray for
2.5-inch and 3.5-inch HDD dual support is also equipped in TS-439U series, which gives
users more choices to deploy the hard drives.
Superior Performance and Advanced RAID Redundancy
The TS-439U-RP/ SP is featured with Intel® Atom 1.6 GHz CPU and 1GB DDRII memory. It
supports RAID 0/ 1/ 5/ 6/ 5+ hot spare, JBOD, Online RAID Capacity Expansion, and Online
RAID Level Migration.
Flexible iSCSI
and Virtual Disk Solution
The TS-439U-RP/ SP can serve as a NAS, an iSCSI target server or an iSCSI initiator. The
built-in iSCSI target feature provides an affordable IP-SAN (Storage Area Network)
alternative for business. You can set up the NAS to expand the storage capacity of the
existing application servers, such as database server and mail server in an economic way.
Moreover, the VDD (Virtual Disk Drive) feature is supported on the TS-439U-RP that you can
use the built-in iSCSI initiator to connect to other iSCSI targets on the network to
expand the storage capacity of the NAS.
Redundant Power Supply for Higher Reliability
The TS-439U-RP is designed with two 150W power supply units which prevent the TS-439U-RP
from downtime, in the event of a short circuit of one power supply. Even if one of the
power supplies fails, the other one will take over to supply the full power and the
TS-439U-RP can operate as usual.
Secure Data Protection by AES 256-bit Volume-based Encryption
The TS-439U-RP/ SP’s dominant "volume-based encryption" feature secures the
server data by AES 256-bit encryption. Even if the hard drives were stolen, there is no
need to fear the confidential data would be leaked since the data can only be accessed by
an authorized password.
Versatile Applications for Business and Corporation
The TS-439U-RP/ SP supports file sharing across Linux, UNIX, Mac, and Windows platforms.
Versatile business are supported, e.g. file server, FTP server with encryption, printer
server, PHP/MySQL supported web server, encrypted remote replication, Windows AD (Active
Directory) SSH login and web page SSL login.
High Performance NAS for Business
Benefits of Dual Gigabit LAN Deployment
Failover
The dual LAN ports can be configured as failover which allows the NAS server to sustain
the failure of one network port to provide continuous services.
Load Balancing
The two LAN ports of the NAS can be configured as load balancing mode for bandwidth
aggregation to boost the file transfer speed (works with managed Ethernet switch with
802.3ad configured).
Multi-IP Setting
The TS-439U-RP/ SP can be deployed with two IP settings for sharing among different
workgroups in two different subnets.
High Reliability, Disaster-proof NAS for Business
DOM Architecture with Embedded Fail-safe Dual OS
All the OS and applications are embedded on the DOM. The NAS allows system booting without
accessing the physical disk sectors and that avoids unsuccessful system startup caused by
bad block sectors or file errors on the hard drives. Two operating systems are built on
the DOM for system booting alternatively upon every system startup. When one fails, the
other one will be used to boot up instead, and the failed OS is recoverable from the other
healthy OS.
Advanced RAID Management with How-swap Design
The NAS offers advanced RAID 0, 1, 5, 6, 5 + hot spare, Single, and JBOD disk
configurations. It also supports hot-swap design that a failed drive can be replaced by
hot swapping without turning off the server. Besides, the best-in-class RAID on the NAS
brings users a higher level of data security by allowing one more hard drive failure than
other NAS of the same level.
Online RAID Capacity
Expansion
The storage capacity of a RAID configuration can be expanded by replacing the hard drives
with larger ones. All the data will be kept and seamlessly moved to the newly installed
hard drives. There is no need to turn off the server during the process.
Online RAID Level Migration
You can upgrade the disk configuration to higher RAID level with the data retained. There
is no need to turn off the server during the process.
Virtual Disk Drive
(VDD) adds flexibility to storage expansion along with ease of management
The unique "Virtual Disk Drive" adds flexibility to expand the capacity of NAS.
By using the built-in iSCSI initiator, the NAS can connect to other iSCSI targets on the
network and turn them into virtual disks, which become multiple single volumes on the NAS.
Up to 8 virtual disks can be stacked. The NAS serves as the storage stack chaining master.
The user only needs to connect to this single entry (QNAP NAS) and is able to reach and
use all the iSCSI target storages on the network.
Built-in iSCSI
Target Service
The TS-439U-RP/ SP can act as a NAS and iSCSI target server at the same time. It provides
a cost-efficient iSCSI solution to set up an IP-SAN. You can make use of the built-in
iSCSI target service to add up to 8 iSCSI devices. Different iSCSI Target LUNs (Logical
Unit Number) can be defined as storage expansion or backup destination of the existing
application servers, such as database servers and mail servers.
Furthermore, the "Virtual Space Allocation" (Thin Provisioning) feature is
provided which allows you to flexibly allocate the capacity of iSCSI LUN (Logical Unit
Number) at the beginning stage without the limitation of the volume space. When the
physical storage capacity of the volume is going to be full, you can easily expand the
storage capacity by "online RAID capacity expansion", or adjust/ remove the
current unused volume space according to the demands.
Smart Power Management
Redundant Power Supply
The TS-439U-RP can be equipped with two power supply units, each of which is capable of
supplying the power for the NAS independently. If one of the units fails, the other one
will take over to supply the power. You can replace the failed power supply unit without
turning off the server.
Hard Disk Standby
The hard disks can be configured to enter standby mode if there is no disk access within
the specified period.
Schedule Power on/ off
The flexible schedule power on/off feature is provided on the NAS for you to manage the
NAS server's up time according to the working hours.
UPS Support
The TS-439U-RP/ SP supports the majority of USB UPS devices which enables the users to
store the data in time and avoid critical data loss when power outage occurs during data
transfer. It also supports advanced stand-by mode setting that you can set the time for
the server to enter standby mode when an abnormal AC power supply is detected. When the
power resumes, the server resumes to the operation status before the power outage.
Auto Power on After Power Loss
You can configure the NAS to turn on/ off when the AC power resumes after a power loss.
High Manageability NAS for Business
Sharing Files across Windows, Mac, Linux, and UNIX
The NAS is designed for users to share the files across Windows, Mac, Linux, and UNIX
environment.
Windows AD
The Windows AD feature enables you to import user accounts from AD domain to NAS to reduce
the time and effort for account setup, and the users can use the same set of login name
and password.
Web File Manager
The TS-439U-RP/ SP provides Web File Manager for you to easily download, upload, and
manage the files on the server by web browser.
Ease of User and Share Folder Management
The TS-439U-RP/ SP supports batch creation of users and share folders to save your time
and effort in account and folder creation. For the security of Windows network
environment, you can hide or show network share folders.

port range setup is also supported.
- Write-only access right on FTP server: The third party partners are allowed to upload
data to the NAS but not able to read or edit the data on FTP server.
Policy-based Automatic IP Blocking
To prevent the NAS from malicious attacks, you can create an IP filter policy to allow,
deny, or auto-block the IP address or network domain which attempts to connect to the NAS
via SSH/ Telnet/ HTTP(S)/ FTP/ samba/ AFP.
Powerful System Management Tools
