TS-439U Series Turbo NAS

Slow

Overview

QNAP TS-439U Series 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.

Superior Performance and Advanced RAID Redundancy

The TS-439U Series 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 series 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 series 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 server 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 Series’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

The TS-439U Series 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.

(TS-439U-RP only)

Advanced RAID Management

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.

Virtual Space Allocation (Thin Provisioning)

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 regardless of the physical volume capacity. When the physical storage
capacity of the volume is going to be full, you can easily expand the storage
capacity of the NAS by “Online RAID Capacity Expansion”.

Flexible Built-in iSCSI Solution

For business, a high-performance and flexible storage expansion solution for the
existing application servers is required. However, DAS (Direct Attached Storage) is
not an efficient solution and a Fiber Channel SAN is too expensive and
complicated to implement.

The TS-439U Series 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.

AES 256-bit Volume-based Data Encryption

The encrypted file system feature enables you to build encrypted disk volumes on
the NAS for the first time installation. The disk volume is securely protected by
AES 256-bit encryption. An encryption key is required to unlock the encrypted
volume to access the server data. This prevents data leakage if the server or the
hard drives were stolen.

Volume 2

Virtual Disk Expansion

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.
