QNAP TS-239 Pro Tower

QNAP TS-239 Pro is the new generation 2-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.

The TS-239 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 TS-239 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.

The TS-239 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.

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.

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).

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

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.

The Turbo NAS supports RAID 1 Mirroring for non-stop service and easy maintenance. When data crash occurs, the administrator can be alerted by e-mail alarm and LED indication. The hard disk drive can be replaced by hot swapping without turning off the server. The intelligent data rebuilding capability allows users to replace a failed drive by hot-swap. This enables automatic data rebuilding to the new drive without suffering from any system downtime.Powered by Intel 1.6 GHz CPU and 1GB DDRII memory, the TS-239 Pro is the 2-bay NAS with the best hardware specifications in the current market. The NAS comes with two Giga LAN ports which can be configured for network failover, load-balancing, and multi-IP setting. Advanced disk configurations such as RAID 0/ 1, JBOD, Online RAID Capacity Expansion and Online RAID Level Migration are supported.
The TS-239 Pro can serve as a NAS and an iSCSI target server. You can make use of the iSCSI target service to set up the NAS as a device for storage capacity expansion or a backup server of the existing servers on the local network. The “Virtual Space Allocation” (Thin Provisioning) feature is provided that you can flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at the beginning regardless of the physical volume capacity of the NAS.

To meet the demand for high security data protection of the business users, the TS-239 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 fear of confidential data leakage if the hard drives or the NAS were stolen. Moreover, the TS-239 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!). It is an ideal storage solution for your office network.
