HDD/SSD enclosures

TS-439 Pro Turbo NAS QNAP TS-439 Pro is the new generation 4-bay 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.

Powered by Intel 1.6 GHz CPU, 1GB DDRII memory, the TS-439 Pro delivers superior performance for multiple business applications. Advanced RAID configurations, including RAID 0/ 1/ 5/ 6/ 5+Spare, JBOD, Online RAID Capacity Expansion, and Online RAID Level Migration are all supported.

Feature-rich Applications for Business
The TS-439 Pro supports file sharing across Linux, UNIX, Mac, and Windows platforms. Different applications are supported, e.g. file server, FTP server, printer server, web server, and encrypted remote replication. Also, windows AD (Active Directory) is supported to help create an easy-to-access environment and lower the maintenance cost. SSH login and web page SSL login enable users to transfer, store, and share data securely.

The Most Affordable and Flexible iSCSI Solution
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 for SMB. You can set up the NAS to expand the storage capacity for existing application servers, such as database server and mail server in an economic way. Moreover, 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.

Secure Data Protection by AES 256-bit Volume-based Encryption
The TS-439 Pro'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 that the confidential data would be leaked since the data can only be accessed by an authorized password.

*Note: Data encryption functions may not be available in accordance to legislative restrictions of some countries.

Easy Setup and Low-cost Maintenance
The handy LCD display on the NAS provides a speedy and easy approach to initialize the NAS and set up the RAID configuration without using any computer. The system information and settings are also displayed for easy management. The schedule power on/off feature is available on the NAS for you to flexibly manage the NAS server's up time according to the working hours. Also, the smart Wake on LAN is supported for convenient remote wakeup of the NAS in the local network.

Easy Setup for RAID Configuration

Touch-N-Go PC-less Installation
You can use the handy LCD to finish the first time installation in 3 simple steps. The NAS will automatically complete the hard disk formatting and RAID building.

Benefits of Dual Gigabit LAN Deployment

Failover Supported for Network Reliability
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.

Better Performance with 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 for Serving Two Different Subnets
The NAS 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 Hot-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.

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-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.

Furthermore, the "Virtual Space Allocation" (Thin Provisioning) feature is provided which allows you to flexibly allocate the capacity of iSCSI LUN (Logical Unit Number). 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.
