TS-439 Pro Turbo NAS

Overview

QNAP TS-439 Pro is the new generation 4-bay model of the worldwide
award-winning Turbo NAS Series designed to deliver high performance and
reliable server features such as advanced RAID protection, built-in iSCSI
target service, and AES 256-bit volume-based encryption for small business.

Powered by Intel 1.6 GHz CPU and 1GB DDRII memory, the TS-439 Pro

The TS-439 Pro can serve as a NAS and an iSCSI target server. The built-in
iSCSI target feature provides an affordable IP-SAN (Storage Area Network)
alternative. Also, 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.
supports RAID 0/ 1/ 5/ 6/ 5+Spare, JBOD, Online RAID Capacity Expansion,
and Online RAID Level Migration. To meet the demand for high security data
protection of the business users, the TS-439 Pro supports AES 256-bit
volume-based encryption. The encrypted disk volumes of the NAS must be
unlocked by the encryption password to be accessed, which eliminates the

Moreover, the TS-439 Pro supports file sharing across Linux, UNIX, Mac, and

Windows. It provides numerous applications, e.g. file server, FTP server, printer

server, web server (with phpMyAdmin, MySQL, SQLite, Joomla!). The TS-439

Pro is an ideal storage solution for your office network.
fear of confidential data leakage if the hard drives or the NAS were stolen.

Advanced RAID Management Flexible Built-in iSCSI Solution

Advanced RAID Management with How-swap Design

The NAS offers advanced RAID 0, 1, 5, 6, 5 + 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.

Built-in iSCSI Target Service

For small 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-439 Pro 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.

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”.

AES 256-bit Volume-based Data Encryption

The TS-439 Pro’s dominant “volume-based encryption” 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.

Benefits of Dual LAN Deployment

Primary Network Connection

Secondary Network Connection

1. Data flow from clients

2. Data traffic evenly distributed
to balance network loading

Support access of multiple IP from different LAN areas

Network Failover

Failover allows the NAS to
sustain the failure of one
network port to provide
continuous services.

Load-Balancing

Bandwidth aggregation is
supported to boost the file
transfer speed (works with
managed Ethernet switch
with 802.3ad configured).

Multi-IP Setting

The NAS can be deployed
with two different IP settings
for sharing among different
workgroups in two different
subnets.

Touch-N-Go PC-less Installation

You can use the handy LCD to finish the first time installation in 3 simple steps. The
TS-439 Pro will automatically complete the hard disk formatting and RAID building.

DOM Architecture and Fail-Safe Dual OS Protection

All the OS and applications are embedded on the DOM of the TS-439 Pro to
allow system booting without accessing the physical disk sectors, which
prevents 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.
