TS-439U Series Turbo NAS

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

(TS-439U-RP only)

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.

Overview

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.

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”.

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.

AES 256-bit Volume-based Data Encryption

Virtual Disk Expansion

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.

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.

The fan rotation speed is automatically adjusted according to the server's temperature.

You can also define the system temperatures to trigger high speed or low speed rotation

of the fan. By manually setting the fan rotation speed, the fan will rotate at the defined

speed continuously.

S.M.A.R.T. & Advanced HDD Health Scanning (HHS)

The NAS supports Hard Disk Drive S.M.A.R.T. (Self-Monitoring Analysis and Reporting

Technology) for monitoring the HDD status. Moreover, the NAS is embedded with HHS

which supports disk checking and bad blocks scanning.

Flexible Built-in iSCSI Solution

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.

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.

RAID 1 Mirroring RAID 5 (3 HDD)

a. RAID 5 (4 HDD)

b. RAID 6 (4 HDD)

c. RAID 5 + spare (4 HDD)

Hard Disk Standby

The hard disks can be configured to enter standby mode if there is no disk access

within the specified period.

Redundant Power Supply

The TS-439U Series supports 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.

Schedule Power on/off

The flexible schedule power on/off feature is provided for you to manage the NAS

server’s up time according to the working hours.

UPS Support

The NAS supports the majority of USB UPS devices which enables you to store

the data in time and avoid critical data loss when power outage occurs during

data transfer.
