QNAP TS-439U-SP/4TB NAS/storage server Intel Atom® 1 GB DDR2

Specifications

Product Description

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. 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. 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 sa
