Specifications

Product Description

Modern business requires a secure, reliable, and high-performance data center to store important digital assets. To easily and securely back up, protect, and share the stored information are also essential to business productivity. QNAP TS-639 Pro is the new generation 6-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-639 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. The Most Affordable and Flexible iSCSI Solution The TS-639 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. The server managers 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 innovative "Virtual Space Allocation" (Thin Provisioning) feature is provided which allows the server managers to flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at the beginning regardless of the physical volume capacity. Feature-rich Applications for Business The TS-639 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. Secure Data Protection by AES 256-bit Volume-based Encryption The TS-639 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. Excellent Hardware Expandability The TS-639 Pro supports five USB 2.0 ports and two eSATA ports. The users can connect the external storage devices to the NAS for server data backup or expanding the capacity of the server. Easy Setup and Low-cost Maintenance The handy LCD display on the NAS provides a speedy and easy approach for IT administrators 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 IT administrators 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. Superior Performance NAS for Business The test results show that TS-639 Pro delivers superior performance (over 300Mbps when serving 16 clients), under single disk configuration. The throughput of other NAS brands of the same level only reaches a half or less than that of QNAP TS-639 Pro. It reflects the TS-639 Pro's capability as the best file server solution in a business environment. 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. 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. Onl
